Nearsightedness, or myopia, as it is medically termed, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus. Nearsightedness occurs if your eyeball is too long or the cornea has too much curvature, so the light entering your eye is not focused correctly.

Keratoconus is a corneal degenerative disorder, in which the cornea becomes progressively thin and steep, resulting in irregular astigmatism. The front of the eye, therefore, is "bulging" and irregular in topography. The presenting complaint is poor vision and inability to correct vision well with glasses, and sometimes, contact lenses.

Presbyopia is a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects. Presbyopia may seem to occur suddenly, but the actual loss of flexibility takes place over a number of years. Presbyopia usually becomes noticeable in the early to mid-forties. |

A cataract is a clouding of a part of the eye known as the crystalline lens. The lens is a clear tissue located behind the pupil - the dark circular opening in the middle of the iris or colored part of the eye. The lens works with the transparent cornea, which covers the eye's surface, to focus light on the retina at the back of the eye. When the lens becomes cloudy, or cataractous, light cannot pass to the retina properly, and vision is blurred and decreased.

Some people do not produce enough tears or the appropriate quality of tears to keep the eye healthy and comfortable. This is known as dry eye. Tears are produced by two different methods. One method produces tears at a slow, steady rate and is responsible for normal eye lubrication. The other method produces large quantities of tears in response to eye irritation or emotions.

Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly.
