Prescription eyeglasses are composed of frames and lenses. While the shape and color of a frame are mostly related to your personal style, the type of lenses you choose has an impact on the function of your glasses. This guide explains the different options available so you can make the best decision for your vision and lifestyle.

What Types of Eyeglass Lenses Are There?

While all prescription lenses are designed to correct refractive errors, such as near- and far-sightedness, other features differ depending on the materials used. 

Made of thermoplastic, polycarbonate lenses are lightweight and highly impact-resistant, so they’re ideal for active people and those who wear specs all the time. Trivex plastic is also impact-resistant and even lighter and thinner than polycarbonate. 

If you want prescription sunglasses, get polarized lenses. These reduce glare, which is essential when driving on sunny days. There are also photochromic lenses, which change from transparent to tinted when exposed to sunlight. This allows you to wear only one pair of glasses, no matter the situation. 

What Coatings & Treatments Can They Get?

Lenses can also include different coatings, including UV-blocking treatments. Much like your skin, your eyes require protection from harmful UV rays to prevent vision issues, including macular degeneration and cataracts.

When you opt for lightweight or impact-resistant lenses, anti-scratch coating is also recommended to prevent damage due to drops.

Anti-reflective treatments further reduce glare and reflections, which increases visibility when driving at night. They also look more transparent in photographs because they don’t reflect camera flash.
