The effects of ageing upon the recovery of contrast discrimination following exposure to a bright source of light (glare recovery) were investigated. A total of 65 subjects were tested, with a distribution of ages ranging from 16 to 79 years. Total glare recovery times were relatively constant up to about 56 years of age, after which they became significantly prolonged. Contrast thresholds to a small spot target gradually increased with age.
