people havin weak eye sight and using spectacles con also be a pilotand what if they've corrected it by Lasik

Answer 1

It depends. Lasik surgery helps some people. In general, if a person's eysight will correct to normal (20/20) then they can get a private pilot's license. But not military--the standards are more stringent.

But--a person whose eyesight can't be brought pretty close to normal won't be allowed a license--and certainly not someone who is legally bind (sigh).

Answer 2

It does not matter, if it is corrected by Lasik. Because it is then normal vision without use of external correction aids like glasses.
Please understand that it is more a physical inconvenience when you use external accesories and the risks if there is a displacement of the accessory which is the primary reason why it is deprecated.

Answer 3

c its like dis,dat you should have a 6/6 vision.
