Eyewea Lenses, Coatings and Options When Ordering
Basic lenses are recommended plastic lenses for low-to-moderate prescriptions shown on a prescription as +/- 0.25 to 2.00. If your prescription is higher than this or if you prefer thinner lenses, please see our other Extra Thin Hi-Index 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 +/- 2.00 to 4.00. At a 1.6–index, you’ll be amazed at how thin your eyeglass lenses can be!
Thin & Light Polycarbonate Lenses
Polycarbonate lenses are the most impact-resistant lenses and are 30% thinner than the standard optical lenses but more impact resistant than thinner lenses and are especially recommended for children’s eyeglasses and for sporting activities. Standard polycarbonate lenses are usually recommended for prescriptions ranging between +/-4.00 and also cylinder ranges between +/-2.50. If your prescription is higher than this, please refer to our Extra Thin Hi-Index lenses.
Extra Thin Lenses
Hi-Index extra thin lenses are 45% thinner than regular plastic lenses. These lenses are recommended for prescriptions above +/- 5.00 and above and cylinder ranges +/- 3.50 to 5.00 for maximum results.
Transitions- Light Adjusting
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, the 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 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.
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.
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 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-Glare or Anti-Reflective 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.
