Conventional plastic lenses can be tinted to almost any color and density. Plastic lenses can be scratched but can have an optional scratch protection applied. On impact, they will splinter.
This is the most impact resistant lens material available and are always the lens of choice for young people and other active patients. Polycarbonate lenses are high index and are usually the lightest, most comfortable lenses. They absorb all harmful UV light and can be made with ultra thin edges because of their unique strength.
Modern technology has created lenses that bend light differently so that stronger corrections are thinner and lighter weight than when made in conventional materials. Such lenses used for stronger corrections are more attractive because they are thinner. They absorb all harmful UV light and can be tinted to any shade or color. These are excellent for people who have high prescriptions.
A material similar to polycarbonate but thinner and more dense. We specifically recommend this lens to wearers of drill mount frames, where the ear pieces and bridge are mounted directly to the lens.
Most sunwear is ineffective in reducing the blinding and painful effects of sun glare and the health risks of UV exposure, at any time of year. Unlike ordinary sunglasses that do little more than darken or reduce brightness, polarized lenses actually eliminate dangerous sun glare. They are the top pick for a wide variety of outdoors activities and sports such as sailing, fishing, skiing, golfing, biking and jogging. They are also highly recommended for driving in daylight and in fact can greatly reduce the glare that comes off a long, flat surface such as the hood of the car or a highway. Polarized sunglasses can also be used indoors by light-sensitive patients or by those exposed to bright light through windows. The lenses come in several colors and materials. Many polarized lenses feature AR coating on the back of the lens for even better clarity and reduced back glare.
