Our frames

1. Metal:

a) Standard metal is generally lightweight.  Most metal frames are usually composed of a nickel/steel alloy. 

b) Stainless steel is lightweight and corrosion resistant.

c) Titanium frames are hypoallergenic, the lightest of metals, and are superior in resisting corrosion.  Titanium frames are the best choice for anyone that has experienced frame peeling in the past or whose frame has turned green in color around the nosepads.

d) Flexible or memory metal frames are made of a titanium alloy which allow for extreme flexing.  Frames made of this type of material are best in durability and require minimal adjustments.

2. Plastic:

Plastic frames are mainly composed of a zyl material which makes these frames a nice lightweight choice.  Plastic frames usually have no nosepads which may appeal to those who take on and off their glasses frequently.

3. Rimless and Semi-rimless:

Rimless consists of no frame on the front of the glasses.  The glasses are supported by either metal or plastic temples, “frame arms”, which are drilled into the lenses. 

Semi-rimless implies half the glasses are supported with a frame and the other half (usually the bottom) is without a frame.

4. Spring hinge/Flexible hinge:

Spring hinges can be used in all types of frame materials.  These pieces allow frames to flex where the temples “frame arms” meet the frame front.  This feature helps relieve stress from everyday wear and tear.

About our Lenses

All of MyGlasses.com premium lens packages (good, better, and best) automatically come with a built in scratch resistant coating and 100% UV protection.

Lens Styles

1. Single vision lenses are used for one area of focus (distance, near, intermediate or computer).

2. Progressive or multifocal lenses are used for multiple viewing tasks.  The distance prescription is on the top of the lenses which progressively changes to the reading prescription as you move from the top of the lenses to the bottom.  These lenses have no visible lines and appear as a single vision lenses. 

3. Bifocal lenses consist of two areas of focus separated by a visible line.  The top   portion of the lenses typically provides a distance viewing correction, and the   bottom segment corrects for near vision. Occasionally, your doctor may prescribe the top portion of the bifocal as intermediate vision and the bottom as near vision.  

Plastic

Conventional Plastic (BASIC)

Conventional plastic also known as hard resin or CR -39 is a lightweight but thick lens material.  We no longer recommend this material because so many superior lens options are available today with very little difference in cost.  If this remains your lens of choice, we recommend only standard eyeglass prescriptions, (those with + or – 2.00 diopters) anything above this will result in too thick of lenses. 

Polycarbonate (GOOD)

Polycarbonate lenses are both lightweight and impact resistant.  This material is recommended for children’s and sports eyewear.  Polycarbonate lenses are an ideal choice for prescriptions within a range of + or – 4.00 diopters.  All polycarbonate lenses provide 100% UV coverage.

Aspheric Polycarbonate (BETTER)

Aspheric Polycarbonate lenses are thinner and lighter than regular polycarbonate lenses.  This material works well with any prescription, especially those above + or – 4.00 diopters.  Again, all polycarbonate lenses provide 100% UV coverage.  
 

1.67 Hyper Index (BEST)

Hyper index lenses are the thinnest and lightest lenses available.  This material works well with any prescription and is the best choice for a prescription above + or- 4.00 diopters.  This lens material provides 100% UV protection.  

Glass

Glass lenses are the oldest type of prescription lens.  This lens material is the heaviest and least impact resistant lens choice.  Glass lenses are naturally scratch resistant.  In today’s market, very few eyeglasses are filled with glass.  MyGlasses.com does not offer glass as a material choice for your lenses. 

Anti-Reflective / Anti-Glare Coatings:

MyGlasses.com provides and recommends anti-reflective / anti-glare coatings for all lenses.  Anti-reflective / anti-glare coatings offer outstanding lens clarity by eliminating unnecessary reflections.  These coatings are ideal for any lens wearer, especially computer users and night time drivers.  Anti-glare coatings help minimize eye fatigue caused by unwanted reflections on the lens.  Anti-reflective coatings have the added benefit of enhancing the cosmetic appearance of any lens.   

Basic Anti-Reflective (Good)

This coating performs well and offers glare free viewing, with comfort, clarity and UV protection.  These lenses are not as durable as the Better or Best choices.  These lenses, though scratch resistant, are more easily scratched. You will have to clean your lenses more often and they will not be as easy to clean as the Standard or Premium AR.

Standard Anti-Reflective (Better)

This coating performs better than the Basic AR, but may not work as well as the Premium AR.  These lenses will provide crisp, reflection-free viewing, and the lenses will be easier to clean and more scratch resistant, but not at the same level as the Premium AR.

Premium Anti-Reflective (Best)

Premium anti-reflective coating is the best choice.  These lenses provide the clearest vision, are the most scratch resistant, and the easiest to clean. They repel water, oil and grime so stay cleaner longer.
