What do I need to begin?
Make an appointment with your eye doctor at least every 2 years.  Its very important that your eye health is monitored.  

When you get the prescription, your doctor might want you to purchase your glasses there.  You are not required to do so.

You pay your doctor to examine the health of your eyes, and to give you a prescription for your eyeglasses.  You may take that with you and shop wherever you desire.


How Do I Read My Prescription?
An eyeglass prescription is written in a standardized format however sometimes they can be hard to understand.   Here are what the numbers mean:

The letters OD (usually the top line of your prescription) and OS (usually the bottom line) in front of a prescription let us know which eye each row of numbers is for.

OD (Oculus Dexter) = right eye
OS (Oculus Sinister) = left eye
OU (Oculus Uterque, Oculus Unitas or Oculus Uniter) = both eyes.

(Note - PL = PLANO; a placeholder for the number zero)

SPH - Sphere or Spherical
The first number in the prescription is the Sphere (or Spherical) and it is the spherical refractive error (farsightedness or nearsightedness). When there is a minus sign in front of the SPH number, the patient is nearsighted (meaning they would need glasses to see things that were far away like the TV).  A plus sign would indicate someone who was farsighted (meaning they had trouble reading a menu or their watch). So then, People who are Nearsighted would need "distance" glasses, and people who are Farsighted would need "reading" glasses

CYL – Cylinder
The second number in the prescription is the Cylinder and it is used to indicate a correction for astigmatism. (An eye that is no longer round but more like an egg or football shape).  If there is no astigmatism, you may see a zero or the letters DS or SPH after the first number to let the optician know that the doctor didn’t just forget to write in the astigmatism.   (note:  -75 = -0.75   //  +125 = +1.25)  If your prescription does not have an astigmatism correction just choose zero

The last number in a basic prescription is the Axis or direction of the astigmatism. Astigmatism, a football-shaped eye, can be measured in any direction around the clock. The Axis numbers indicate the orientation of the football shape.  (note:  X = axis – sometimes written as X 80 or AXIS 080 - - - - the number "80" is just used for this example, your number will probably be different)

There may be additional numbers in a glasses prescription.  The ADD numbers denote the amount of power that gets added to the distance prescription (SPH) and is used to create your "reading-only" prescription for "readers" - or for the lower portion of bifocal and progressive lenses.  

Note:  Sometimes you might have a prescription that has "NV" on it.  This means it is for Near Vision – or in other words....for reading glasses or "readers".  This means that the SPH power and the ADD power have already been added together by your doctor for your readers.  

Otherwise it would be a "DV" prescription Distance Vision prescription and, if you wanted to make "readers" out of them, there would be an ADD number and our lab would do the addition to get reading glasses instead of distance glasses.

If there is only one ADD power on your prescription for bifocals, this means that the same ADD power is used for both eyes. If there is no ADD power given, leave this section blank when ordering.

A Prism correction is used to treat muscular imbalance or other conditions and the numbers are usually left blank on the prescription and not many people need this correction. Sometimes, if the basic prescription is followed by a small number with a superscript (1^) it indicates prism correction. There may be more than one set of prism numbers for each eye

NOTE ON ENTERING YOUR PRESCRIPTION INFO:   Very importantly, pay close attention to plus and minus sign as this will greatly affect the lens. If there is anything on the prescription you are not familiar, please call our Customer Service and we will be happy to assist you.

ALSO VERY IMPORTANT  - - When choosing frames for bifocal or progressive lenses, you must have a lens height of at least 28mm.  It is for this reason that our site blocks sizes smaller than 28mm so you cant make a mistake.

The following are a few examples of sample prescriptions:  
Note that each of the following examples is for the same eyeglasses prescription.  Also note that the ADD, which is for the reading portion of a bifocal or progressive lens is not in the last example because there is a separate NV or Near Vision portion for this prescription.

Here is some more detail on prescriptions if you like.........
On a typical prescription, you will see two sets of rows. Most of the time top portion is for your OD or right eye while the bottom portion is for your OS or left eye.

•    For Distance Correction, there should always be a value under Sphere and most of the time it is negative. Its abbreviation is 'D.V.' which stands for Distance Vision.
•    For Reading-only correction, there should always be a value under  Sphere and most of the time it is positive. If there is a value under Near Vision (N.V., N.V.O.) then enter the power in the BOTTOM half of the form and leave the ADD power blank or ("0.00").
•    For Astigmatism Correction, please note that that Cylinder (CYL) and Axis are always provided together. For any value of Cylinder there should always be a value for Axis. Some doctors use positive (+) cylinder and some uses negative (-), there is a big difference between the two so please pay close attention to the positive and negative signs. If you don't have astigmatism correction, doctors might just leave it blank or simply SPH or DS which means Sphere or Diopters Sphere. Axis should be from 1-180 degrees, if you see a value like '5' under axis, this is also the same as '005' or '5 degrees'. It should always be a whole number and there should no be decimal point on the axis.
•    For Bifocals and Progressive Lenses, please check with your eye doctor whether the Addition is for Bifocals or Progressive. Most of the time, compared to the Bifocal Addition, the Addition of the Progressive is higher by 0.25, so please verify. An indication to know if your prescription is for Progressive, is a PAL note written on the prescription. Only one ADD, means the addition for the Left and Right eyes are the same. Please be advised that we process a minimum of +1.00 and maximum of +3.00 for Addition powers.
•    Eye Doctors will sometimes leave out the decimal point on the Sphere, Cylinder and Addition. For example, -25 or +175, this is understood -0.25 and +1.75.

What is the PD (Pupillary Distance)?
PD, or pupillary distance, is the distance from the center of the pupil (the black spot in the eye) of one eye to the other. This measurement refines the positioning of your lenses within the frame you have chosen.

This measurement is necessary to ensure the correct positioning of your lenses within the frame you have chosen. It can be provided in minutes by your optician or doctor, and so we recommend that you ask for it when you have your vision checked. Or you may ask someone to measure it for you but advise them to be at about an arm's length away from you.

You can also have a friend measure or measure by yourself by facing a mirror. For single vision lenses, you may choose to use an average PD of 63mm, but for Bifocal or Progressive lenses, we still strongly recommend to get this information from your optician.

For your information, most adults' PD are between 55-65mm and most kids' PD's are between 42-54.

Why isn't the PD (Pupillary Distance) on my prescription?
The PD is part of the fitting process. Many doctors do not put it on your prescription because they assume you will come back to them to get the glasses or else you will get the measurement done wherever you buy them. They do measure it and you can call them and ask them.

If you are getting SINGLE VISION glasses (for distance or reading) then you can measure it yourself (see below). If you are getting MULTI-FOCAL glasses (for bifocal or progressives, you should CALL YOU DOCTOR and get the correct PD as it can really make a difference with these types of glasses.

Why do I have 2 numbers for my PD measurement?
Sometimes the PD is measured from one pupil to the other and sometimes it is measured from the center of your nose to each pupil.  If you have 2 numbers, you can add them together and you will get a numbers somewhere in the sixties (millimeters)

Sometimes you will have a Distance Vision PD (eg 64mm) and a Near Vision PD on the same prescription.  You can use the Distance (usually the larger one) unless there is more than a 5mm distance in which case you average – take the middle.  Example:  D=67 / N=61   use 64mm


What types of frames do you sell?
We offer a variety of plastic, metal, memory or flexlite (bendable frames that retain their shape), titanium, safety and sports frames. All of our eyeglasses come complete with complimentary case and cleaning cloth.

Do you have a retail store where we can fit your frames?
We currently don't have a retail store. Being a pure internet shop is what allows us to offer our customers such low prices.

For fitting, we recommend that you look at the interior sidebar (arm) of a frame you already own to see the dimensions that suit you best. You can compare this with the dimensions on the Details Page for the frame you are interested in getting.  

Note: Eyeglasses Dimensions are measured in millimeters: Lens width - Nose Bridge - Sidebars x Lens Height
50 - 14 - 135 X 24

I would just like the frames so can I get non-prescription lenses fit into the frames?
Absolutely, on the Details Page, under the section How Will You Use Your Glasses? please click on the 'Fashion only' box and we will send you the frames with non prescription lenses.

Do you offer children's frame?
Definitely!! Our children's frames are for children under 10 and children with small faces. For children in this age group, we still recommend them to have a consultation with an optometrist

Choosing A Frame

How To Determine The Right Frame For Your Face
In learning how to select eyeglass frames, there are steps that can be taken to avoid a sloppy purchase that results in poor fitting frames. For many people in the market to buy new frames, making a fashion statement can sometimes be as important to the consumer as quality of vision. However, it is important to remember that knowing how to select eyeglass frames is not strictly an enhancement of one’s beauty. Comfort also plays a vital role in determining whether or not a purchase is made.

If you are buying eyeglass frames for the first time, looking at frames in an optical store in a shopping center or at your optometrist's office is often a good place to start.  Be sure that you select eyeglass frames for comfort and write down measurements of some frames you like.
If you have already worn glasses before, then you can use those to help you size the frames.  Your current glasses will have measurements for the bridge (the part over the nose) the frame width (from the tip of temple to the tip of the other temple) and the arm length (from tip of the temple to the tip of the end of the arm)  If you measure your glasses with a millimeter ruler (better than inches because the resolution is smaller) then you can compare to the measurements we have for every pair of glasses on our site.  In this manner, you can compare several frames to yours and get an idea of what it would mean to have, for example, a lens height of 35mm versus one that is at 26mm.  Give it a try and you will find that its quite easy to do.
The Temple Arm Length can vary up to about 10mm from what is written on your frames as they are adjustable (you bend the "earpiece" to fit comfortably.  If you have worn glasses, you know that this is an easy thing to do.
The Bridge Measurement, aka DBL or Distance Between Lenses, (nose) can be easily adjusted by moving the nose pads. Typically, the bridge measurement is between 15 and 20 mm and so a variation in this from your glasses to a new pair will not make any difference.
The Frame Width is not adjustable in any way so it is important to stay about 5mm from the measurement on your glasses. 
The Lens Height and Width are provided to help you get an idea of how big the glasses will seem on your face.  Typically, if the Frame Width and Temple Arm Length are similar to yours, then the frame will be a suitable size for your face.  If you really like a frame and are not sure, simply measure the glasses you have (sunglasses will work too) and you will get an idea about how big they will be on your face.

Remember, every persons face is shaped slightly differently than the next and sometimes the face shape may change the shape of the frames you want to buy. There are a few tips that can be followed in looking for the perfect pair of frames. If you have plenty of facial hair, larger frames tend to mask certain features. Smaller cut frames may enhance a bearded look. Also, in knowing how to select eyeglass frames, try to avoid frames larger than your head. In other words, if you have a smaller shaped head smaller frames will not mask your features. More on this below.........................
Comfort and Fit 

A few tips to consider in knowing how to select eyeglass frames is to make sure your eyes are comfortably positioned with the middle of the lens. Again, if you currently have glasses that fit, you should not stray too far from the numbers on that frame.  Avoid large set frames if your eyes are set close together. When wearing the frames, your eyebrows should line up parallel with the top part of the frame of your glasses. Lastly, choose a frame set that appears different from the shape of your face. If you have a rounded face, your frames should probably be a shape other than round.

Very Strong Prescriptions and Minimizing Lens Thickness

We often are asked from customer with strong prescriptions, "I have a very strong prescription (greater than +/- 6.00).  What do you recommend as the most aesthetically pleasing lenses without breaking the bank?"

Answer:  In addition to order a higher index lens (1.61 or higher), the smallest frame possible that looks good on your face will help as well. I also recommend a frame that is fairly round or oval (no corners), where you look right through the center of each lens. These techniques minimize lens thickness.

Choosing Frames To Suit Your Face Shape

If you have been wearing glasses already, and chances are you have worn glasses of some kind before – even its been sunglasses – you probably have a good idea of what you like.  But sometimes its nice to hear how other people go about it.

Basically there are three things to think about when deciding on the right frame for your face.

• Shape - The shape of the frame should be in contrast with the shape of your face.
• Size: The size of the frame should be in scale with the size of your face.
• Color:  Its great when your frame highlights your best features.  Hair, eyes etc.

What Shape Is Your Face?

If you have been wearing glasses already, and chances are you have worn glasses of some kind before – even its been sunglasses – you probably have a good idea of what you like.  But sometimes its nice to hear how other people go about it.

 Basically there are three things to think about when deciding on the right frame for your face.

• Size: The size of the frame should be in scale with the size of your face.
• Color:  Its great when your frame highlights your best features.  Hair, eyes etc.

Seven Basic Face Shapes - What Shape Are You?  Print this page and ask a friend.

Of course everybody has a slightly different face shape, but faces tend to fall into one of these categories.  You may find that you fit into a couple of categories and thats OK, but ask a few people you know and see what they say.  There will most likely be a “winner”  - and that's you! Ha!

Still, you might not want to think of yourself in a category......who wants to think of themselves as a “square-head” or a “diamond-face”  but..........we have to have some way to describe your face so try not to get offended.  I have been called a “bone-head” before.......and I have no idea what frames go with that.

Basically, when people choose frames to go with a face shape, the idea is to compliment it.  Often they are used to balance the basic shape.  So a round face would use square or rectangle frames.  Square face shapes would use more round or oval frames to balance the strong lines.

If your head is as tall as it is wide, then you are in this shape category.  You might want to try shorter-lens frame styles, ones that have more width than height and possibly narrow ovals.  This will help to soften the features if that is what you want to do.

If your head is as tall as it is wide, but there are no angular features, then you are in this shape category.   Rectangular shapes would work well.

If your face is a little wider than round face shape. Try eyeglass frames that are about as wide as  the widest part of the face.  Make sure they are not too tall or too narrow.

If your face is longer than it is wide With no angular features, you are in this face shape category. To lessen the length, for balance, try frames that are a little wider than normal, and maybe have thicker arms and temples to counter-balance the length of the face

Triangle (Base-Down)
This face shape has a narrow forehead that gets wider in the cheek and chin areas. Try frames that are  accented with color or decoration on the top half.  Cat-eye shapes or semi-rim frames work well for this.

Triangle (Base-Up )
This face shape has a very wide top third and small bottom third. Try frames that are wider at the bottom.  Also, very light colors and materials such as metal or titanium as well as rimless frame styles work well.

These face shapes are narrow at the eye line and jaw line, and the cheekbones are often high . To soften the cheekbones, try rimless frames or oval and cat-eye shapes.

Color - What is best for you?

You probably have tried many colors of clothes and have an idea what suits you best.  Glasses are no different.  You want to look at the basic components of color that are already a part of you and look for colors that match. That would be your skin, eyes and hair color.

 Colors tones are referred to as “cool” - which include blue to black tones and “warm” which include the softer reds, yellows and oranges as well as creams and browns.

When you have figured out if your coloring is  "warm" or "cool," then you can find the eyeglass frame colors that will suit you the best.

Some frame colors which are best for warm coloring are: khaki, gold, peach, copper, orange, soft pink, cream, red, soft blue and light tortoise.

Some frame colors which are best for warm coloring are: brown, grayish-blue, dark purple, magenta, hot pink, dark-green, blue, dark tortoise and black

The "Go For It" Approach
As you can see from the information above, there are certainly some guidelines to follow which will help you to make sure your eyeglasses fit your face and coloring.  BUT............. do they fit your personality?  There certainly are times when we stretch out with our fashions, and at Greateyeglasses.com we are committed to providing you with quality eyewear at great prices so you can stretch out with your eyewear too. 
There definitely are enough celebrities with large, round faces that have large, round glasses and look great!!!  I'm sure you have seen people with long faces wearing rectangular glasses with blue lenses and they look great too!

So we say "Go for it!"  HAVE FUN!!!!

How does the Opti-Fit system work?
The Opti-Fit system is useful for seeing if a frame is suitable for your face.  Choose a model with a face shape that is similar to yours and you can see how the glasses might look on your face.  

If you choose to upload your picture to the site, just follow the instructions.  Typically, a jpeg picture that is not too big of a file size will work better as it just loads faster.  You can put up any size image though and you will be able to resize it by moving the arrows.  NOTE:  These frames are NOT TO SCALE – because we would have no idea what size you are making your picture right?  So keep that in mind.  YOU MUST MEASURE YOUR FRAMES USING THE COMPARISON METHOD DESCRIBED IN THE FITTING YOUR FRAME SECTION.


What types of lenses do you sell?

Different Types of Prescription Lenses
(depending on the needs of your eyes, the optician will use the following lenses)

Single vision lenses have only one viewing area throughout the lens. This corrected area can be for far distance, near distance or reading. Your glasses come with plastic high-index 1.56 lenses included. You can upgrade to a thinner and lighter lens for an additional charge.

High index lenses are used to make your lenses lighter and thinner.  It doesn't matter if they are single vision, bifocal or progressive.  They are compressed lenses that offer better optical viewing through them. For higher prescriptions they not only reduce the weight by up to 50% but also reduce the thickness by up to 60% making them more attractive cosmetically.

1.56 index, 1.59 index, 1.61 index and 1.67 index.The higher the index, the thinner and lighter the lenses. We also offer 1.60 index Water Repellent/Anti Fog Lenses if you will be using your prescription eyeglasses in this type of environment.

Polycarbonate lenses are thinner and lighter than traditional plastic eyeglass lenses. They also offer 100 percent ultraviolet (UV) protection and are up to 10 times more impact-resistant than regular plastic lenses. This combination of lightweight comfort, UV protection and impact resistance makes polycarbonate lenses an excellent choice for children's glasses, sports eyewear and safety glasses.

We highly recommend Polycarbonate Lenses for rimless glasses as they reduce the stress cracks that will eventually happen with these types of glasses.  


Polycarbonate lenses cannot be made with Sun Darkening lenses (transitional – darken outdoors).  

Polycarbonate lenses can come in tints (permanent color), but they are usually lighter (50% dark) compared with non-polycarbonate lenses (up to 90% dark).

I use my glasses for….
By telling us what you will use these glasses for helps us to make sure that your lenses are made correctly.

Choosing Distance means that you need your glasses to drive, watch the TV or, in some cases, in order to see your computer screen or the dashboard on your car.

Choosing Reading means that you need glasses to read a menu, book, newspaper or even see your watch clearly

Choosing Bifocal means that you have both Distance and Reading correction in the same pair of glasses.  The top portion of the lens is for Distance and the bottom is for the Reading portion.  

The size of the each section is determined by the SEG Height. (the "line" in "lined bifocals")  We only sell Bifocals that have lines.  If you want to get a multi-focal lens (with more than one correcction) and you don't want lines, you can choose a Progressive Lens.

Choosing Progressive - -  A Progressive lens is similar to a Bifocal Lens but has more than 2 corrections – and no lines.  As you look through the lens from the top to bottom, you can see far to near.  For example, you will be able to clearly see the freeway signs in the top, the dashboard in the middle, and the map through the bottom.

What are the lenses made of?
We use lightweight, high-index 1.56 plastic lenses.  We also offer 'thin-light' and 'super thin' lens upgrades, which are 1.61 and 1.67 high-index lenses as well as 1.74 in single vision glasses. We especially recommend that you upgrade to these lenses if your sphere is +/-2.50 and above. In addition to these, we also provide Polycarbonate Lenses, which are very durable and harder to break.
Our recommendations are as follows:
•    Sphere Power Index
•    +/- 0.25 to +/-2.50 = 1.56
•    +/-2.50 to +/-5.00 = 1.61
•    +/-5.00 and above = 1.67 or 1.74

All the lenses provided by Greateyeglasses.com include UV protection coating to protect your eyes against the Ultraviolet light from the sun and also scratch resistance coating to protect your glasses against scratches from your daily wear. 
For night time driving and a lot of computer uses we offer the Anti-reflection coating, which reduces the reflections of the light from oncoming traffic
You may select from a variety of coatings such as UV-coating and Tint for an additional charge. You may also choose bifocal lenses or progressive lenses with different thicknesses.  These choices can be made on the details page of your frame in the same area where you fill out your prescription.

Do you sell lenses alone?
Sorry but no, we offer our lenses with our frames as a whole package

Do you sell progressive and bi-focal lenses?
Yes we do.  They also known as Multi-Focal Lenses.  Here is a description of their differences.

Bifocal Lenses

Bifocals have two distinct viewing areas within the same lens; the distance area and the near area. The distance area in bifocals is designed like a single vision lens, while the near area contains the distance prescription and the additional amount of ADD power needed to see at a reading distance.

Bi-Focals have that light "line" just below the center-line of the lens that separate the distance upper part from the reading lower part of the lens. Bi- Focal lenses should have an absolute minimum of 27mm height, but we recommend a 32mm or greater lens height to make them comfortable.

What type of bifocal lens do you use?
Sorry but no, we offer our lenses with our frames as a whole package

Do you offer trifocal correction?
We do not offer segmented (three sections with lines dividing them) Trifocal corrective lenses.  We find that most people who move on from Bifocal prefer the Progressive Lenses

Progressive Lenses

Progressive Lenses correct vision for two or three different distances without the visible segment lines seen in bifocal or tri-focal lenses. Instead they have a graduated section in which the power of the lens progresses smoothly from one prescription to the other, allowing the wearer to see clearly at all distances.

Progressive, no-line bi-focal, lenses need to have an absolute minimum of 28mm height, but here again we recommend at least 32mm or higher lens for a more comfortable viewing area. Progressive glasses are the most sensitive to a correct PD so be sure to take an especially accurate PD measurement for this type of order.  If the measurement is off here by ±1.5mm it is still OK.

Segment Height (SEG)


Using a multi-focal lens means that you have Distance and Reading (Near) in the same pair of glasses.  The top portion of the lens is for Distance and the bottom is for the Reading portion. 

The size of the each section is determined by the SEG Height. (the "line" in "lined bifocals")  (See more about this in the "Bifocal and Progressive Lenses" help bubble.  In a progressive lens, the corrections changes from Distance to Reading as you look from the top to the bottom of the lens – however a SEG height is still used to define the reading portion.

This measurement has traditionally been determined at the Doctors office if you purchased your glasses there.  The Doctor would ask you where you want the line to be and then measure the distance from the bottom of the glasses to that line – and then give that to the lab. 

When buying glasses online, you don’t have a way to do that as all frames are different shapes and heights.  The way we take care of this is to take an average of the SEG height that most people use and then describe that as a percentage.

How do you divide the distance and reading portion on Bifocal or Progressive lenses?
Normally, the division is 70% of the lens height for distance and 30% of the lens height for reading. But of course, you are very much welcome to inform us your preference in division. Some people prefer to have a larger reading area (maybe 60/40).  This is called the SEG HEIGHT.

Technically, if your Optometrist is asking, we put the SEG at "the D line divided by two minus 2 mm".   
Please include a note in the comments box as you check out so that we know you would like the change.

Transition Zone is the area of progressive lenses where the distance vision curve gradually changes into the near-vision curve.

Is there an adaptation period to Progressive Lenses?
There is a short adaptation period when you are fitted with your first pair of progressive lenses, which can range from a few minutes to a few days. People with certain types of corrections, including strong plus (+) prescriptions (also called strong farsighted or high-hyperopic) prescriptions, tend to have more difficulty adapting to progressive lenses. These can be difficult to get right and, if you have never bought them before, you may want to get your first pair at a local store as you might have to go back for several fittings. I have used them for years and have had no problem getting additional pairs online.

Are there any frame-size limitations for Bifocals or Progressive lens?
Yes there are limitatiions. Not all frames are suitable for Bifocals or Progressive. Bifocal lenses must have a minimum lens height of 27mm and Progressive lenses must have a minimum lens height of 28mm.
We want to make it easier for you to identify which frame can or can't be done with Bifocal or Progressive by putting a check or cross mark on the description of the frame you are looking at. Also, if the curvature of the frame is too much, you will feel as though you are looking through a fun-house mirror. We aim to stay at a very average level of curvature for glasses in this category to help insure a good result.
If this is the first time you are getting Progressive lenses, you may want to go to an optician in your neighborhood. If you are used to wearing Progressives, then it is easier to get used to another pair. If you need more advise, please don't hesitate to contact our Customer Service Department.

Prism Lenses

What are Prism Lenses?
Innovative prism glasses can significantly improve the vision and the daily lives of patients with hemianopia, a condition that blinds half the visual field in both eyes resulting from damage to the optic pathways in the brain. Most commonly caused by strokes, it can also be the result of brain damage from tumors or trauma.

If you need to get Prism Lenses, please check the "I Have A Prism Correction" box in the "3. Enter Prescription And Pupillary Distance" section

You should have the number for your prism correction (.5, 1, 1.5, etc) and the Base Information (Base In, Base Out, Base Up or Base Down) on the prescription from your doctor

There is an additional $10 charge per each lens that requires a Prism Correction

Lens Color Tint

Tints are permanent and DO NOT change in the sun. They also cannot be changed (lighter or darker) once they are made.

You do not need to choose a tint if you have already chosen a lens which will darken in the sun. (Sun Darkening also known as Photochromic or Transitional Lenses)

Do you offer prescription sunglasses?
Oh Yeah we do! We suggest that you select of a frame of your choice and make sure to click on the 'Tint' option on the Details page. Currently, we offer yellow, purple, red, green and blue colors and light (10%), medium (50%), dark (90%). The 20% is the lightest and 80% is the darkest and most commonly used in sunglasses. With all these choices, you can really have some fun!!

NOTE – The thinner the lens, the harder it is to get the tint really dark. If you had a strong prescription for example, and you purchased a thinner lens, they would not be as dark as if you did not get the thinner lens – even with the same prescription strength

Do you offer the tint that changes color indoors to outdoors and vice versa?
Yes, they are called Photochromic lenses. We call them Sun Darkening and you might have heard the term "Transitions" which is a registered trademark of a particular brand. When you are indoors, the tint will be very light. And when you are outdoors, it will get dark depending on the direct exposure to sunlight. Please be advised that these lenses do not get as dark as a typical sunglasses and they also do not work in automobiles as they respond to Ultraviolet light, which is filtered out by the tint in automobile windows.

Can we have lenses both tinted and photochromic (sun-darkening)?
No. Lenses are either photochromic, where the degree of the tint changes, or constant tint, depending on what you wish to have. The two features therefore, are incompatible and can not be selected simultaneously.

What kind of tints do you have?
We have a large color selection of tints that include a Light, Medium and Dark density with a Solid or Gradiant (dark to light from top to bottom) shading.

The Darkest tint is similar to most sunglasses. With a UV coating, this is a good way to get glasses that are suitable for daily wear. We also provide a Polorized Brown or Polorized Grey lens, which is the same as is used in high quality sunglasses. These are better for sports and situations with extreme sun and reflective glare as the Polarizing Lenses filter the glare and provide UV protection as well.

The following Tint colors are available and this is approximately what the shading would look like in your lens

Polarized lenses are available in Brown, Gray and Grayish Green.


What kind of coatings do you have?

Anti-Scratch. Tuff Coat, and UV (Ultra-Violet)
We offer free Anti-Scratch and UV coating. You can upgrade that out our "Tuff Coat" Coating if you like. It is way more resistant to scratches and we would recommend that you get it if you are in situations that your glasses might become easily scratched (running through bushes for example)

Anti- Radiation, Anti Glare
You can also order an Anti-Radiation and an Anti-Glare coating. The Anti-Radiation coating is primarily for people who spend a lot of time at their computer. It is a 3-layer coating that combines UV, anti-scratch and anti-reflection coatings. For most people the included UV and anti-scratch coating is sufficient. There is an additional cost for the anti-radiation as the process is much more involved when applying all three.

The issue of Anti-Glare is a personal decision. Many people who need their glasses to drive at night find the anti-glare is very helpful as it reduces the halo effect around headlights, etc. Some anti-glare coatings really attract smudges, but that has not been the experience with our lenses.

Water-repellant and Anti-Fog Coating
These lenses have a special coating that helps to minimize the fog that forms on your glasses when going from cold to warm – outside to inside in the winter for example. It cannot be combined with color tints.



How can you charge such low prices?
Very simply, our frames prices are so incredibly low because we are 100% internet retailers. We have no retail costs to pass on to consumers. As soon as you place your order, we proceed to lens production and glasses assembly immediately, bypassing typical retail costs. This is why most other eyeglasses retailers have to mark up their prices so high.

Another reason why we have such low prices is that we do not carry "designer" frames. Typcially, the frames that are available to most optical stores are patterned after "designer" frames although they are not "knock-off" cheap frames like you sometimes see on the internet. Often, it is the other way around and "designers" simply choose already available frames from eyeglasses manufacturers and put their logo on them. Our mission is to provide quality, stylish and durable frames at a price that allows our customers to have many pairs. Put a pair by the bed, another in the car, a tinted pair in the boat, (a cool pair in the fridge? - yeesh! ). Maybe a blue pair to go with that great tie or red to go with that new dress?


What is the quality like with your eyeglasses?
Many sites sell cheap eyeglasses that fall apart, but at GreatEyeglasses.com we carry only top quality frames, with durable hinges and we use high quality lenses. We are not selling cheap eyeglasses - We are delivering a great value


How do I place an order?

When you see a frame that you like - click on the frame to see; a close-up of the frame, available colors and also check the measurements against your own glasses to make sure that they are in the right size range.

When you are ready to checkout, your prescription information is also going to be with your selections in the cart for your review. If you wish to change prescriptions on your next selection (perhaps you are buying for a child or as a gift) you simply change the numbers in the prescription box and it will be saved and available as you shop. Note: we do not keep prescription or credit card information in your profile once you complete your purchase and leave the site. We encourage you to keep your prescriptions up to date. At least every two years. Even if you feel that you can see well, its important to see your doctor in order to make sure your eyes are healthy. There are many issues that can come up regarding the health of your eyes - so please keep on top of that.

How do I obtain my prescription?
Your optician or eye doctor is required to provide you with your prescription. Be sure to ask for a clear and legible copy. Also make sure to ask for the PD (Pupillary Distance) as many doctors will not give that to you if you don't ask.

What if I get a pair of glasses and I cant see properly?
If you get a pair of glasses and you cannot see, then there are only 3 things that can cause it. Your doctor gave you an incorrect prescription, you entered the prescription info incorrectly on our site, or our lab made an error.

In order to fix it, IT IS EXTREMELY IMPORTANT that we determine where the error is so that the new pair wont have the same problem.

PLEASE EXAMINE YOUR RECEIPT AND COMPARE THE PRESCRIPTION INFO TO THE PRESCRIPTION PAPER FROM YOUR EYE DOCTOR. If you entered the info incorrectly, please let us know and we will send you a form for the return.

IF YOU ENTERED THE INFO CORRECTLY – You should bring the glasses to your doctor. If the doctor made the error, then you have the glasses right there with you to compare the prescription in your new glasses to the prescription that you received. The doctor can determine this in about 3 min and you usually don't need to make an appointment. Just give them a heads-up call.

IF THE DOCTOR FINDS OUT THAT THE ERROR IS OURS, then you can call us and we will have them replaced immediately.


What if my frames need adjustment after I receive them?
When you receive your glasses, they will probably need a little adjustment. Maybe the nosepieces are a little loose or tight. Maybe the ears are not bent right and they fall down your nose. Sometimes the arms on plastic frames seem a little "bowed". These are all natural because, even though we choose "average" sizes for you, everyone is a little different when it comes to fitting.

Know this........

Its very easy to adjust glasses. It may not be spot-on right away, but over a few days you will get them right. If you always bought glasses from your Optician before, then that person adjusts them and, for the most part, they probably get it right, but often times you have to go back or you just bend them as you see fit (pardon the pun) They use their fingers and sometimes a small pair of needle-nose pliers to work on metal frames, and a container full of warm, glass beads to heat up plastic so its flexible.

Adjusting Metal Frames

If you have metal glasses, the nose pieces can be opened or closed by using your hand. There is really no need to use a pair of pliers or anything kind of hard tool. The same applies to the part that goes over your ears. Just bend them with your fingers and try them until its comfortable.

Its probably obvious, but you want to make sure the nose piece is wide enough so the glasses sit on the place on your nose that you like. Then you can adjust the arms so that they don't fall off of your face if you lean forward. Don't try and get them to sit on your nose in the right place by adjusting the arms. Its really hard to get it right if you do it that way. Remember........nose first and arms second!

Adjusting Plastic Frames

With plastic frames you need a hair dryer or warm water to warm them up (do not use hot water as it can mess up the Anti-Reflection Coating if you have it).

The same approach applies as you would use to adjust metal frames. You want to bring the nose pieces together or apart until they sit on your nose at just the right place. Then you can adjust the ear pieces.


Sit down with a hair dryer held between your knees and have it facing away from you. (Duh! You will figure out why pretty fast if it's pointing towards you!)

Now warm up the bridge of the glasses a bit by putting the bridge (the piece between the lenses that sits on your nose) right up against the hair dryer. Maybe about 20 sec at first. Then feel it and see if it feels warm to hot. If not, then do it for another 10 sec or so. Now pull them away and hold them with both hands as though you are looking at them on someone else's face. Put your index fingers on the top of the frame and your thumb on the bottom like you were picking up something off of a table. Then bend them so that the bottom parts of the nose-piece part of the frame starts to come together. '

NOTE: You do NOT need very much adjustment to make a HUGE difference in how they feel, so just do it a little bit - not so that you can even see a difference. (although you cant see anyway because you don't have your glasses on!)

WARNING!! – the glasses will be HOT – so be careful when you put them on your face. (Remember.... We did warn you and are not responsible if you sear your beak by not testing them first to see how hot they are)

Now just do it a bit at a time. In front of the dryer for a little heat, a little flex, and then try it on.

BIG NOTE - - you do NOT want to flex the frame very much because you could pop the lens out.

When the glasses feel like they are sitting comfortably on your face, you can work on the arms.

Do the same thing with the arms – one at a time. If you set the glasses upside-down on a flat surface, so that the bent part of the arms are on the surface, you can see if the arms are hitting the surface in the same way. One may be raised a bit compared to the other. It could be OK as not all people's ears are the same height on both sides – but its a good way to check anyway if they feel like they are off but you can't tell why.

You can even bend the arms so that they bow in or out from your head depending on whether you have a round head or not.

We also suggest trying an optical center, in most places they will be happy to assist you free of charge. Your doctor is a good source as well because that office will want to retain you as a patient and making sure you see well should be their main focus (pardon the pun) and not just selling you glasses. You can also adjust them yourself.

You can also check out a video. Just click here or go to this tab and click on "Video: Adjusting Glasses" (NOTE – put link to videos here - "Video: Adjusting Glasses)
