Myopia Causes and Prevention

Ive been reading about myopia, mostly some recent work out of japan. Our obsession with 20/20, at distance, seems to be exacerbating the issue. Im not sure that these will help. We perhaps need to admit that not everyone needs to shoot a gun, fly an airplane or even drive a car. The japanese work is showing that making things perfect at 20ft often makes the eye contort itself to see at the sub-foot range where most reading occurs. Acceptable vision at closer ranges would be a better stand

My theory is that people who always use their eyes to look at short distance objects, like staying indoor and doing indoor activities only, makes the muscles used by eyes to focus -- shorter. People need to go out or at least make it a habit to look at long distance objects or horizon to increase the range of motions involved in focusing.

Does this actually do anything to help your eyes?

Having less focus in your peripheral vision might help slow myopia progression, so possibly. However wearing glasses and contacts automatically add more focus to peripheral vision, signaling the eye to grow. So moving something further away from your face while wearing glasses or contacts may have less of an effect. Having periods of blurry vision, like looking at something far away for some time without glasses or contacts, may be beneficial in that it may signal the eye to become less football

Anecdote, as a teen, I was diagnosed as having myopia (mostly on one eye) and got glasses. I refused to wear them most of the time, during that time I spent more time outdoor, looking further away and also develop an habit to stare at points far away whenever I'm thinking.Since I'm 25, whenever I do an eye test, they tell me that I have a very small amount of myopia on one eye but it's very small and I don't need glasses.Interestingly, when I talked to an eye doctor rec

Wait, so it really is possible to acquire (at least temporarily) nearsightedness from looking at close stuff too much?

Why would exercising your eyes make them need glasses?

Myopia progression isn’t related to eye strain or muscle use. Over focusing on the peripheral parts of the retina tells the eye to grow longer because it thinks it’s over focusing, especially in youth. You should wear corrective lenses as little as possible especially if you do work that keeps your peripheral vision in focus like reading or using a screen.

The eye grows automatically in response to what is in focus. If too much is constantly in focus the eye grows longer to blur it. This is especially important in peripheral vision which is why lenses are finally coming out with blurred edges to slow myopia progression. Ophthalmologists who don’t know this and don’t tell people to use lenses as little as possible and dont think screens cause myopia are negligent (and hopefully will start getting sued until they learn) especially when prescribing l
