In addition to being both thinner and more lightweight than conventional lenses, this material is also 10 times more impact resistant than any other lens material. In fact, a very similar type of plastic is used in the windshields of our space shuttles! They are inherently UV protective and have a built-in scratch resistance. Sometimes referred to as "featherweight lenses," polycarbonate is essential for use in children's eyewear, sports eyewear, or safety glasses.
High Index Lenses
For those who tend to reach toward the higher limits of near-or far-sightedness, we encourage high-index lenses. This special type of plastic refracts light more efficiently, allowing your lenses to be produced with the thinnest edges possible while preserving superior optics. You can finally toss out those old "Coke-bottle" eyeglasses!
Breakthroughs in physics have allowed scientists to produce a lens coating that can significantly reduce the amount of glare that reaches the eyes from extraneous light sources. This can greatly cut down on eyestrain while working on a computer or driving at night by eliminating annoying reflections from overhead lighting and unwanted haloes around headlights. There is a definite cosmetic benefit as well – people will see more of your eyes instead of the reflections off of your lenses. Similar coatings are often used in photographic lenses, computer monitors, and telescopes.
Photochromic lenses have the ability to rapidly change from clear indoor lenses to darkened sunglasses as you step outside. This does away with the need for separate pairs of eyeglasses and sunglasses. Recent breakthroughs have allowed these to be produced in almost any material-polycarbonate, high index lenses included. The lenses are activated by ultraviolet light and will remain dark until the UV light exposure is over.
Tints, UV Coatings, Scratch Coatings
Depending on your visual needs, we have the ability to add mild to moderate amounts of tint in a variety of colors. UV and scratch coatings are recommended for those who choose standard plastic lenses to add protection to and enhance the durability and lifespan of the lenses.
