What are the difference between anti glare and normal glasses?

0 votes

Yesterday, I got my eyes tested and get ready to buy a pair of glasses. I found that most eyeglasses stores recommend anti-reflective coating on the lenses. It is too expensive. I do not know what's the usage of anti-glare coating. Is it necessary?

Anti-reflective coatings allow more light to filter through your lenses than normal eyeglasses. Well, sunlight can oftentimes creep through the top and sides of your glasses, reflect off the backside your lenses, and right into your eyes. By adding an anti-reflective coating on the backside of your eyeglasses, the sunlight travels through the lenses instead of bouncing into your eyes, thus saving you from that backside glare.For this reason, you usually don’t want the anti-reflective coating on the front side of lenses, but rather on the inside only. It also helps prevent you being able to see your own eye in the back of the lenses. That can be weird.On regular eyeglasses, the AR coating is applied to both the front and back of the lenses to help reduce glare and halos. While driving at night, this minimizes road glare and glare from headlights. And while indoors, it helps filter glare from florescent lights, TV screens, and computer monitors. Nowadays, it’s very common for people to get the coating on their everyday glasses. They also help your glasses look better on your face by reducing that white glare you often get on the lenses. This makes it easier for others to see your eyes behind those shiny glasses.
