High Index Eyeglass Lenses
If you have a stronger prescription, you can still get a lense that is lighter weight and thin! These state of the art prescription lenses are able to bend light differently so that stronger prescriptions are thinner than when constructed with traditional materials. These lenses reflect more light than regular plastic hard resin lenses. They are also available with Anti-reflective coating ( AR coating ).
Glass lenses ( see below ) are also available with the slimming advantages of High index but are much heavier. High index plastic uses less material so they are often lighter in weight. High index lenses also absorb all harmful UV light and can be tinted to any shade or color.
Traditionally, glass lenses where the only choice for prescription glasses, and while glass lenses still provide superior optical performance, they are almost twice as heavy as the hard resin variety. Glass can be treated to have greater impact resistance and are also the most scratch-resistant type of lenses.
Conventional hard resin lenses are actually made with CR-39. Eyeglasses made with this popular material are much lighter than traditional glass lenses. Hard resin lenses may scratch more easily than glass lenses but they can also have an optional scratch protection applied. These types of lenses can be modified to any thickness and can be tinted to match any color Hard resin lenses do not require heat treating and they are actually more impact resistant than glass.
These type of lenses are the kind that darken to a mid-gray shade when you go outside, and lighten when you come inside. A convenient and highly fashionable choice, photosensitive Lenses are available in two materials – glass and hard resin. If you stop by our eyewear office in Fort Lauderdale, one of our associates would be happy to show you how photosensitive lenses and see if they are a good fit for your next pair of eyeglasses.
These lenses are the best choice for young people and very active people who wear corrective lenses because they are the most impact resistant. Polycarbonate lenses are ‘high index’, so they will be light, flexible and very comfortable. They can even be constructed with fashionable ultra thin frames because of the strength of Polycarbonate. These lenses also soak up all harmful UV light.
