People 80 years of age and older are  eight percent of the population, but account for close to 70%  percent of all cases of blindness.

Sight loss has also been attributed to a significant factor in mortality. Studies have indicated that falls and hip fractures  increase with vision loss and and can be deadly in the elderly.
