Change in Prevalence, Vision Impairment, Age 40 and Older
Vision impairment is defined as having worse than 20/40 vision in the better eye even with eyeglasses. The prevalence estimate tables and data for vision impairment in this database exclude cases of blindness. People with the least degree of vision impairment may still face challenges in everyday life. For instance, people with vision worse than 20/40 cannot obtain an unrestricted driver's license in most states.
Almost everyone with blindness or vision impairment can benefit from vision rehabilitation, which can help make the most of whatever vision remains.
The visually impaired, excluding those who are blind, total nearly 2.9 million older Americans. The prevalence of vision impairment increases rapidly in the later years, particularly after age 75.
