If you often experience glare when wearing your glasses, an anti-reflective coating may be a good choice. This lens coating is a microscopically thin layer that prevents light from reflecting off of the front and back surfaces of your lenses. This can dramatically improve vision for night driving and may also make it more comfortable to read or use a computer. Anti-reflective coating is especially helpful for high-index or polycarbonate lenses, which tend to reflect more light.
If you’ve scratched your eyeglass lenses, you know how irritating it can be to look out into the world with sub-optimal vision. Scratch-resistant lenses have a clear coating that prevents minor scratches on the front and back surfaces of the lens. Be aware that even a scratch-resistant coating cannot prevent all scratches or lens damage; however, it can be very helpful in preventing minor wear on your lenses.
