Halos and glare are common and bothersome symptoms, according to a study called Needs, Symptoms, Incidence, Global Eye Health Trends (NSight). Most patients experiencing halos and glare say it happens usually in the evening or late at night. The symptoms were commonly associated with bright lights, headlights, being in the dark and nighttime driving. The study surveyed 3,800 spectacle- and contact lens-corrected subjects, 15 to 65 years of age, from China, Korea, Japan, France, Italy, United Kingdom, and United States. See results of the study.
