Dilating eye drops cause close things to be blurry for about 3 hours. He said there are mixed thoeries about what causes near and farsightedness. Environment is less accepted than genetics. Nearsightedness reduces strain on eyes when looking at a computer screen- He answered when I asked what advantages nearsightedness has. he also said that with my eyes, eye exercizes wouldn't help. Exercizes are more for helping eyes focus. I still don't understand. Maybe strengthening muscles for farsighted people can help them focus on nearsighted things, but not vice versa. Most people go farsighted as they get older, I suppose when the nearsighting muscle gets weak with age/ use. Hmm. I'll continue to ask questions
