are conditions where a person cannot see distinctly and comfortably. There are three common eye defects, and they are(i) myopia or near-sightedness, (ii) Hypermetropia or far-sightedness, and (iii) Presbyopia. These defects are corrected by the use of suitable spherical lenses.
Two common eye defects are myopia (nearsightedness) and hyperopia (farsightedness). Myopia is usually corrected with eyeglasses or contact lenses that help focus light correctly onto the retina. Hyperopia can also be corrected with eyeglasses or contact lenses, or in some cases with surgery such as LASIK to reshape the cornea.
you can correct your eye defects by regularly using "Carrot" in your diet, either in form of juice or adding in Salad. Carrot is helpful for increasing your eye sight and is really good for health as well.
the defective curvature on the cornea or lens is called Astigmatism

Surgery on the eye is routinely performed to repair retinal defects, remove cataracts or cancer, or to repair eye muscles.
