Eyeglass Lens Material

Basic lenses are the recommended plastic lens for low-to-moderate prescriptions shown on a prescription as +/- 0.00 to 2.00. If your prescription is higher than this or if you prefer thinner lenses - please see our other Hi-Index lenses.

Thin & Light Polycarbonate Eyeglass Lenses

With an index refraction of 1.59, Polycarbonate lenses are the most impact-resistant eyeglass lenses. They are 30% thinner than the standard optical lenses but more impact resistant than thin lenses and are especially recommended for children's eyeglasses and for sporting activities. Standard polycarbonate lenses are usually recommended for prescriptions ranging from 0.00 to +/-4.00. If your prescription is higher than this, please refer to our Hi-Index lenses (1.6/1.67).

Thin Lenses

Hi-Index lenses are 30-50% thinner than standard plastic lenses and are the lens of choice for those with high prescriptions - prescriptions shown as +/- 0.00 to 4.00. At a 1.6–index, you’ll be amazed at how thin your eyeglass lenses can be!

Hi-Index extra thin eyeglass lenses are 45% thinner than regular plastic lenses at an index of 1.67. These lenses are recommended for prescriptions from +/-2.00 to +/- 6.00 for maximum results.

Hi-Index ultra thin eyeglass lenses are the thinnest lenses available on the optical market with an index of 1.74. These lenses are recommended for those with prescriptions +/-6.00 and above and should be used with an ultraviolet protective coating for premium results.

Anti-scratch coating can be applied to your lenses in order to resist scratches. It’s very effective for lenses in prescription eyeglasses and particularly in children’s glasses. The anti-scratch coating is applied by dipping the lens into a silicone-based solvent. As it cures, there is no tinting or coloring left behind to damage the optics of the lenses. Although the coating is not 100% scratch proof, it does help to prevent minor scratches that can damage the surface of the lens.

UV Coating

Invisible to the naked eye, our UV (ultraviolet) coating provides superior protection for the eyes. Overexposure to UV light may cause cataracts, retinal damage, and many other eye problems. The UV treatment is applied to most eyeglass lenses – except polycarbonate as they have an inherent material property that does not need UV coating – and does not change the appearance of the lens.

Anti-Reflecting Coating

Anti-reflective coatings help reduce reflection on the surface of the lenses. It also improves the efficiency of the glasses since less light is lost. The biggest benefit is the eradication of the reflection itself – making the eyes of the wearer more visible. The coating is also the best solution for computer usage and night driving. It increases light transmission through the lenses, it provides the wearer with the clearest vision possible.

Transitions Lenses - Light Adjusting Lenses

Transition lenses, also known as Photochromic lenses, have a compound that becomes dark when exposed to light and made clear again by removing light. While indoors, the lens tint will lighten and allow as much light in as possible. When exposed to sunlight outdoors, transition lenses will darken depending on the direct exposure to light. It’s just that easy! They also preserve the health of the eye by blocking 100% of harmful UV rays.

Sunlight is reflected or absorbed in horizontal, diagonal, or vertical directions. Polarized sunglass lenses have a laminated surface that contains only vertical stripes (think: vertical blinds), and only vertically-polarized light will be allowed to enter the person’s eyes. The glare will then be eliminated because any horizontally-polarized waves of light will not be able to bypass the polarized filter.

Tinting is applied to both sides of the lens for the look of sunglasses without the polarization effect. It can only be applied to basic lenses with an index of 1.50. Available colors are gray, brown, and green. Tinted lenses should be used in conjunction with an ultraviolet protective coating.
