Abstract

Introduction  Sensitivity to scotomatic glare increases slightly up to the age of 40 years, and above 40 years it shows a more rapid increase approaching an asymptotic maximum above 80 years.1,2 There is a parallelism between glare sensitivity and the clarity of the lens. In young individuals the lens is clear while an increase in density is noticed in individuals above age 40.3,4 In individuals with incipient or mature cataracts, glare sensitivity is exceedingly high, and with aphakic corrections after removal of the lenses, glare sensitivity is lower than expected in accordance with age.1 This relationship between glare sensitivity and lens density suggests that the scatter of light in the lens is to a large extent responsible for the sensation of glare. If glare is a function of scatter of light during the normal physiological increase in opacity of the lens, it would be of great interest
