I heard that laser surgery can now treat longsightedness. Thing is as my eyes must obviously be getting worse hence needing new glasses, what happens after the surgery, do i still need glasses after a few years or not? Also my brothers mate said you can treat yourself by getting a cd walkman wiring it up to double the voltage and stare into the lens thing. frightened to try it as may hurt! Advise (sensible only)

As you age, your lens inside your eye grows. It grows layer by layer and gets stronger and stronger. By the time we are about 40 or so, the lens has grown so big, it's harder to bend. We get readers to help do that work. If we are nearsighted, then we're already focused close, so we won't need the addition to our normal glasses unless we want to wear them all the time, and just look down into the add to read. The addition will be the power increase (positive direction) that corresponds to reading distances.
If one is far sighted, the eyes get stronger so one gets less far sighted. But even so, at 40, need reading Rx.
Eye exercises won't help do anything but strengthen the extra ocular muscles a bit, which may be helpful in people with a neurological condition or weak muscle for some reason.
Vitamins...nope,
secret herbs, ....nope
eye formulas that have been scientifically proven....nope.
The laser correction is more for youngsters who have a fairly long time before reaching 40. If they were shortsighted before surgery and then get corrected to 'normal', when they reach 40ish....yep..readers.
The CD/ laser guy? ..it's not illegal to be that unsavy, but it can be dangerous.

Don't believe the friend of your brother about looking into the laser of a CD player! I don't know if it is strong enough to cause eye damage but, laser vision correction is deffinitely NOT a do-it-yourself project!
The trouble is, if you get the laser correction and you're vision continues to change, you might be stuck with glasses again! Some people claim, once the operation is done, you can't go back and re-do it if your eyes change later on; some people claim they can re-do it. Even if they could re-do it, you would be stuck paying for it again! It is pretty expensive, unless you really, really hate wearing glasses I would pass.

You could only have surgery in one eye. That way, you could use one eye for distance and one for reading. I had that done several years ago. I found that I still needed reading glasses because it wasn't comfortable using just one eye for reading. Driving worked out all right. For shopping, reading price tags, etc., it also worked fine.

Laser surgery works for distance vision and astigmatism. Not for short distance vision.
Forget what your brothers mate says.

laser surgery is very expensive and isn't always succesful I think bifocal contact lenses might help
