Q. What is myopia?
A. Myopia is nearsightedness. A myopic eye can see near objects clearly. Distant objects are seen clearly only with the help of glasses, contact lenses or refractive surgery. Light entering the eye focuses in front of the retina.

Q. What is hyperopia?
A. Hyperopia is farsightedness. A farsighted eye can see distant objects more clearly than near objects, however, neither of them is in crisp focus, especially after the age of forty. Farsightedness can be corrected with glasses, contact lenses, or refractive surgery. Light entering the eye focuses behind the retina.

Q. What is astigmatism?
A. Astigmatism is a condition that occurs when the cornea has more than one curvature (like a football as opposed to a basketball). These multiple curvatures bend light differently and blurred vision is the result. Light entering the eye focuses on or in front of the retina, multiple focal points.

Q. What is presbyopia?
A. A presbyopic eye cannot see near objects clearly when distance vision is corrected with glasses or contact lenses. It usually occurs after the age of forty. Presbyopia can be corrected with bifocal glasses or reading glasses. It can also be corrected with refractive surgery
