Question

Your grandmother is quite upset. She is 82 years old and has been having some serious vision problems. You have suggested quite a few times that she needs to see her doctor. She finally went and she was told that she has cataracts. She feels like she is the only one her age that does. What percentage of adults her age have cataracts?

Answer 1

50%

Step-by-step explanation:

Cataract is an eye injury that strikes and opacifies the lens (a lens behind the iris whose transparency allows light rays to pass through it and reach the retina to form the image), which compromises vision. The evolution is usually slow, and the disease can affect first one eye and only later the other. In short, cataract is an eye injury that makes the lens opaque and blurs the vision, as if there was a mist in front of the eyes. Although it can occur at any age, cataracts are very rare in young people and very common in older people. Cataract affects 50% of the population over 80 years of age.
