I know you never said that this tuff doens't happen, but Lasik isn't a 100% sure thing.
I wear both glasses and contacts, but I have heard of rehabilitation that doesn't require surgery, rather it entails exercises for your eyes, as though you were "working out" your eyes. Maybe hard to imagine, but if you can rehabilitate your arm after breaking it, why not your eyes? I suppose finding the cause of why we have poor vision is an important part of this. Glasses and contacts only offer a quick fix for the problem. They don't address the causes of the problem. Perhaps if we looked at preventative measures and understood why this happens, there would be less cases of it.
And I am by no means a doctor, so I may be way off base on this. |
Nearsightedness and Farsightedness are mainly hereditary. What determines it is during development. You can do some things before the age of 12 or so to try and slow the progression of an eye problem, but after that point things are pretty much set in stone.
What happens with the exercises is that you are trained to focus through the blur.... that is done by your physiological lens. That physiological lens hardens over time and the muscles that control it can no longer change its shape, ie.focus. By your early 40's you only have about 15% of your focusing ability as you had when you were a newborn, hence you need reading glasses to allow you to focus in close. Therefore, the exercises would only theoretically work until you are about 40...
That leaves you with one option. Changing the shape of the Cornea... ie. Laser corrective surgery.
People in Africa generally are not nearsighted. Whereas people in Asia are like 65% nearsighted. Partially Genetic... partially to do with amount of reading done at a young age. More near work = more nearsightedness. However, it is not like you can eliminated near work.
