Bad vision can be caused by nearsightedness, farsightedness, and astigmatism. These can be corrected with glasses, contact lenses, or some surgeries. These conditions are genetic to a certain extent, but may also be influenced by your environment.
Can eyesight be permanently fixed?
Laser-assisted in situ keratomileusis (LASIK) is a surgical procedure that can improve your vision. It permanently reshapes the tissue in the front of your eye, and these changes last your whole life. However, most peoples vision gets worse over time as part of the natural aging process.
Does LASIK work for really bad vision?
The surgeon first cuts a thin flap of tissue from the front of the eye. Then, a laser burns away tissue to reshape the cornea so that light focuses better on the retina in the back of the eye. LASIK can correct vision problems like nearsightedness, farsightedness, and astigmatism.
