What's your prescription by the way? Has it been changing at all?
The Bates method has been around for a long time, with no proven success. I think if there was some way to get rid of glasses that simply, the opticals would be out of business.
I agree with you that doctors are far from having all the answers, but I think the good ones can be very helpful. I would say the majority of doctors, particularly GPs, are useless for problems that they don't handle every day. When you start getting to the specialist level, I think the skill level comes up - this is who the GPs refer to. Then there are subspecialists, who the specialists refer to. It all narrows down the pool of problems they see every day so they have a higher volume of these rarer problems. I think it's hard to find the right doctor, but with a lot of wasted time, I think you can find docs to help you with some pretty weird problems.
On the other hand, there are problems that the medical community has no solutions for.
But then there are also problems that I'd say are hard to deal with because they're subjective - for example "blurry vision"... the criteria for clear vision can vary quite a bit between individuals. Some thing for "pain". The person's feeling about the treatment can also influence it - the placebo effect.
