????: Myopia or near sightedness and hyperopia, far sightedness, themselves don't cause blindness. They are treated with corrective lenses. However, extreme myopia or hyperopia can be associated with certain problems that can potentially blind you.

A 21-year-old member asked:

Can myopia be prevented?

2 doctor answers6 doctors weighed in
Dr. Robert Kwok

No: There is no known way to prevent myopia. It is familial in many cases. However, it is believed that a person who spends a lot of time looking at objects (tv screens, computer screens, books, etc.) at close distances puts pressure on his eyeballs due to the actions of the eye muscles during close focusing, thus changing the shape of the eyeballs and causing myopia. This belief has not been proven.

NO: Posterior vitreous detachment is unusual at your age but may be associated with high myopia. Usually a PVD leaves a floater but can be associated with a retinal tear. The floaters may be distracting but they won't cause blindness.

What's the difference between myopia and astigmatism. Can you have astigmatism without having myopia?

Two separates: Myopia is very near vision and need for glasses beyond a foot or so. You may can read when very close to you but cannot see beyond arms length. Astigmatism is an irregular contour of the cornea and causes waviness and blurring in the pattern of sight. You can have one without the other. Your eye care professional can examine you and correct most of these problems. Seeing it clearer?
