what causes halos around lights
Halos and glare can be caused by eye problems that keep the eye from properly focusing light onto your retina (the thin lining located in the back of the eye). Common eye problems that can cause halos and glare include: Nearsightedness (difficulty seeing things far away) Farsightedness (difficulty seeing things nearby)
Causes of Halos and Glare. Halos typically occur when your surroundings are mostly dim or dark whereas glare is more likely to happen during the day. Halos and glare can be a normal response to bright lights or, in some cases, can be the result of a more serious eye problem.
