These are a great choice for extremely high prescription wearers who want the absolute thinnest lenses possible. When you have a stronger prescription, it is possible to still get yourself a lense that’s lighter weight and thin! These advanced prescription lenses have the ability 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. This lens is another preferred choice for safety eyeglasses and children’s eyeglasses.

Photosensitive Lenses

Higher-index material offers lighter and thinner glasses lenses, making them a fantastic option for glasses wearers with a solid prescription. These lenses will be the best choice for teenagers and very active people who wear corrective lenses because they are probably the most impact resistant. Polycarbonate lenses are ‘high index’, so they will undoubtedly be light, flexible and incredibly comfortable.

Eyeglass lens material doesn’t change the corrective power of your glasses. Rather, eyeglass lens types offer different cosmetic and lifestyle benefits to the wearer. In most cases, CR-39 lenses are widely acceptable as the standard. They’re very reasonable and durable, but they have to have special coatings applied to become scratch-resistant, blue-light reflecting, and UV reflecting. Nevertheless, they’re still the norm and offer a lighter, stronger eyewear experience than glass.

Trivex lenses have lots of the same qualities as polycarbonate lenses and provide crisp, clear optical clarity.

The factory-applied coating — called Fog Free — eliminates the condensation of moisture on lenses that triggers fogging. They are an excellent choice for strong prescriptions, including -4.25 to -6.75 and +4.25 to +6.75.

With normal glasses, much of the light reflects off the lenses. Basically, the light reflections are a visual and cosmetic problem.
