Quality of life in patients with no light perception in one eye
A study evaluating quality of life found that patients with no light perception in one eye who were asked to imagine the same scenario in their second eye, were willing to trade almost 3 out of every 4 years of their remaining life in return for perfect vision in both eyes. Those with light perception to counting fingers would trade around 1 of every 2 remaining years, and those with 20/200-20/400 would trade around 1 of every 3 remaining years.
