For many years, eyeglasses were made entirely of glass, which could easily be broken. These days, most glasses are made of high-tech plastics. We have lighter lenses that do not break easily and can be treated with a variety of filters for added protection.
Polycarbonate lenses are impact resistant, ideal for people who regularly play sports or who work in an environment where eyeglasses can easily be broken. These lenses also provide ultraviolet protection.
Trivex lenses are similar to polycarbonate lenses but are made of newer, lightweight, thin, impact-resistant plastic. Some people find they offer better vision correction than polycarbonate lenses.
High index plastic lenses:
Because these lenses are so thin, they’re ideal for people who require string prescriptions without the need for “coke bottle” lenses.
As opposed to spherical lenses, aspherical lenses offer different degrees of curvature, making them thinner and flatter, and also giving them a larger usable portion than standard lenses. This flatter lens design helps reduce unwanted magnification of the wearer’s eyes, while providing better peripheral vision for the wearer.
Polychromatic lenses are unique for how they shift from clear to tinted when exposed to sunlight. They’re prescription sunglasses and regular glasses in one.
With modern lenses softer and more prone to scratches than glass lenses, scratch coats can compensate for this by making your lenses as scratch-resistant as glass. If you have kids with glasses or are hard on your glass yourself, this becomes an especially important coating.
Not only do anti-reflective coatings eliminate reflections on glasses, they can help you make better eye contact. This feature makes glasses virtually invisible, and might even eliminate those glare spots in photos.
Fortunately, polycarbonate and high-index plastic lenses have 100 percent UV protection built-in, so you typically don’t need to add it.
