The material of eyeglass lenses may or may not have much of an impact on how well they correct your vision. However, different lens materials suit different lifestyles. It’s worth exploring which is the best for you at your next eye exam.
Read on to find out about the prescription glasses lens material that suits your needs so you can be better prepared to make a selection next time you’re in the market for new lenses.
These provide excellent visual correction, though they are on the heavy side and are more likely to crack and shatter. Because of these reasons, glass lenses have become less popular over the years.
While glass lenses are still available, most lenses are now made of plastic. It’s lighter, cheaper and safer than glass, while producing similar results in terms of your eyesight.
High-index plastic lenses
These are even lighter and thinner than the average plastic lenses. They’re made out of a special plastic that refracts light in a different way compared to standard plastic lenses, which allows for less material to be used. These thinner, lighter lenses make the glasses more comfortable to wear. They’re also considered to be more aesthetically pleasing, though they come at a higher cost.
These are flatter, lighter and thinner lenses that are a strong choice for anyone who needs thicker lenses. This means that the lens will bulge less out of the frame—meaning, aspheric lenses can reduce magnification of the eye. These flatter lenses also lessen distortions that occur with peripheral vision, making your vision considerably crisper.
This material is used in safety glasses, children’s eyewear and sports goggles. This is a lightweight, impact-resistant material that’s unlikely to crack or shatter. Polycarbonate lenses also include built-in ultraviolet protection. However, some people with astigmatism may experience poorer quality of vision and other issues with this material.
Trivex is a relatively new material on the market that is similar to polycarbonate in that it’s durable and lightweight. This material includes higher quality optics and, therefore, somewhat superior vision compared to polycarbonate.
These can be for anything from scratch-resistant coatings to anti-reflective and anti-fog coatings. Some of these treatments may come built into the lenses, or they can be added later. These measures can help the lenses last longer as well as improve comfort and visibility. You may want special treatments, such as a UV-blocking coating that lessens the impact of the sun’s rays on your eyes.
