Different mechanisms of action. Age related deterioration of eyesight, presbyopia, is caused by hardening of the lens and weakening of focusing muscles. Myopia is probably caused by lack of exposure to the extremely bright light of the sun during childhood and adolescence. Twenty year old hunter gatherers have great eyesight, sixty year old ones, not so much.
- justjash 7y ago> Myopia is probably caused by lack of exposure to the extremely bright light of the sun during childhood and adolescence Is there research on this? Just wondering since I ended up having issues with nearsightedness in my early 20s but feel like I spent a lot more time outdoors as a child compared to children these days.
