1.Distance, Reading, Single Vision Lenses
You can select various color tint and various coating as Add-ons.
Lenses have only one viewing area throughout the lens. This corrected area can be for far distance, near distance or reading.
For Single Vision Lenses (All Time Wearer), ADD is not available for input on prescription. It is mandatory to provide ADD data on prescription for bifocal and progressive lenses, while it is optional for Single Vision Lenses (Reading only).

2.Progressive Lens No Line
Progressive lenses are the closest to how natural vision is that you can get in a pair of prescription eyeglasses. They are more than just a defined near and distance correction in one lens. Rather, progressives provide a smooth transition from distance through intermediate to near, with all the in-between corrections included as well. This constant graduation of the prescription means that you can look up to see in the distance, look ahead to view your computer in the intermediate zone, and drop your gaze downward to read and do fine work comfortably close up.
it comes automatically with anti-scratch and UV protection. To coat progressives with anti-reflection, you need to pay only $4.95. It‘s well worth the investment. All progressive eyeglasses at glassesshop.com are made of types lenses as follows:
1. Plastic Lenses Index 1.499
2. Ultrathin UV Middle Index 1.553
3. Ultrathin UV High Index 1.600
4. Diamond Clear Polycarbonate High Index 1.591
5. Ultrathin UV High Index 1.670

3.Free Form Progressive
Compared with traditional progressive lenses, the Free Form Progressive have the following advantages:
a. The lenses are easier to adapt to give their extremely low aberration level and smooth transition.
b. Wider field of vision at all distances because the progressive surface is closer to the eye. The intermediate and near visual fields are up to 35% larger than conventional progressive lenses. They will ensure the widest fields of vision in comparison to traditional progressive lens manufacturing. With a Rear Surface progressive, as much as 50% larger viewing zones will be achieved.
c. Immediate adaptation due to reduced dizziness and balance problems. Great for wearers changing from Bifocals to Progressives.
d. Quicker adaptation thanks to optimal design ergonomics that fully respect the routine movements of new progressive wearers and wearers of progressive lenses with a different design.
And the biggest advantage with Free Form Progressive eyeglasses is that they are customized to the individual. In the past progressive lenses could only be made from lenses with certain pre-determined base curves, which gave sub-optimal optics. Free Form Progressives are customized to individual prescription and frame parameters they increase the field of view and decrease distortion in the periphery of the lens.

4.Bifocal Lens with a Line
A bifocal lens means a lens with two points of focus. A small portion of the eyeglass lens is reserved for the near-vision correction. The rest of the lens is usually a distance correction.
Generally, you look up and through the distance portion of the lens when focusing on points farther away, and you look down and through the bifocal segment of the lens when focusing on reading material or detail work up to about 18 inches away. All bifocal eyeglasses at glassesshop.com are made of plastic index 1.499. it comes automatically with anti-scratch and UV protection. To coat bifocals with anti-reflection, you need to pay only $ 4.95. It‘s well worth the investment.

• Plastic Lenses Index 1.499
• Our Standard optical lenses. CR-39®

These lenses are the ideal choice for most single vision prescriptions because they are so much lighter and less breakable than glass lenses. Traditional plastic lenses are made from a hard resin that is cast or molded in the wet state into lens blanks. These plastic blanks can be ground into specific shapes to fit any lens frame. Plastic lenses are great for prescription sunglasses due to their tint ability factor. CR-39 is a trademark of PPG Industries, Inc.

• If your prescription is above 4.00 +/- then we would like to suggest the ultrathin lenses.

If your prescription is above 4.00 +/- and you want your slightly stronger prescription to be cosmetically more attractive then we recommend ultra thin lenses. These lenses are thinner and lighter than they have ever been before by using the highest index of refraction at 1.600 and a most advanced material. High prescriptions no longer mean thick, chunky lenses that can only be glazed into heavy frames. Middle Index 1.600 lenses are up to 33% thinner than regular plastic lenses!

• Diamond Clear Polycarbonate High Index 1.591
• It is required for children, sports, danger zone and any impact environment.

Polycarbonate – Your Choice for Safety Polycarbonate is a unique material that was originally used primarily for industrial safety glasses because of its very high impact resistance qualities. It is now used for children, sports wearers, certain rimless frames, or anyone requesting greater impact resistance in their lenses. These lenses are the same thickness as our standard thin (1.6) lenses. Poly carbonate lenses are a very strong lens type which, as a higher refractive index material are also slightly thinner. All polycarbonate lenses automatically come with ultraviolet protection and we never charge an additional amount for this feature.

• Ultrathin Lenses High Index 1.670
• If your prescription is above 6.00 +/- then we would like to suggest the thinnest lenses.

These are one of the thinnest optical plastic lenses generally available on the market today, perfect for people with very high prescriptions (+/-6.00), or for anyone who wants very elegant glasses which may be lighter in weight.

  Polarized lenses (driver lenses),index1.499

Daylight travels in waves oscillating in all directions of three-dimensional space. Polarized light also travels, but mostly moves in two dimensions: horizontally and vertically. Vertical light brings useful information to the human eye, enabling us to see colors and contrasts, while horizontal light simply creates optical noise or glare. Where light strikes a non-metallic surface such as water it often reflects primarily in a horizontal plane. This creates a high concentration of glare which can be selectively blocked only by a good quality polarizing filter.
For years, boaters and fishermen have used polarized sunglasses to reduce reflected glare from the water surrounding them.
Besides boaters, drivers benefit the most from polarized sunglasses, for polarizing lenses are the best lenses for driving. Polarizing lenses selectively filter out the horizontal light, thus the drivers will enjoy a clearer view along with elimination of glare. Once wearing polaroid sunglasses, the drivers will benifit:
Glare-free vision
Enhanced contrasts
100% UV protection
Significantly less eye-fatigue
Outstanding color perception

  Anti-Reflective Coatings

  Anti-reflective coating For driving & Sport

As light encounters a lens three things happen. Some of the light passes through the lens, this is called refraction, some is absorbed and converted into heat energy (very small amounts) and the rest bounces off. When light bounces off the lens this creates glare. Glare or reflections can be annoying and in some severe cases can decrease visual acuity. To improve both the vision through the lenses and the appearance of the glasses, an anti-reflective coating (also called AR coating) is applied. The AR coating consists of several layers of metal oxides applied to the front and back lens surfaces. Each layer is scientifically calculated to block reflected light. The result is that you'll see a reduction in glare, annoying reflections and halos around lights. This is a great safety benefit when you're driving at night.
Also, the AR coating reduces both internal and external reflections on the lenses themselves, creating a nicer cosmetic appearance. Internal reflections appear as rings that make lenses look thick. External reflections mask your eyes from a clear, complete view when someone is looking at you. So with an AR coating, eyeglass lenses appear thin or non-existent, and your eyes look more natural.
                                  

With sunglass lenses, an AR coating is better applied only to the back surface of the lens (the surface nearest the eye). Because sunglass lenses are so dark, the AR coating can wind up looking smeary on the front surface. Coating the back side helps reduce the reflections of light that enter from behind you and bounce off the surface into your eyes. A back-side coated sun lens is much more comfortable than an uncoated sunglass.

Anti-scratch coating is a scratch resistant coating that is most commonly applied to optical lenses. This coating is applied by dipping the lenses into a silicone-based solvent. As the anti-scratch coating cures, there is no tinting or coloring left behind to impair the optics of the lenses. The coating does not interfere with how the lens functions, but creates a permanent bond that greatly reduces the occurrence of happenstance hairline scratches.
