Anti-glare lenses are commonly used by patients who are sensitive to glare. They may be used by individuals if they find that using anti-glare lenses improves their comfort whilst working for long periods of time on devices with screens, such as a smartphone, computer, television etc.
Anti-glare lenses are also useful when you are driving at night or performing outdoor activities when reflected light (off of a lake's surface, for example) can cause significant glare symptoms. Whilst indoors, they are also useful as it improves eye contact with other individuals as they are able to see your eyes behind your glasses.
