Good eye sight can only be maintained by having regular eye check-ups done by an ophthalmologist.
Most people go through in life without any disease of the eye, while others might need corrective lenses at some time. Regular eye check-ups help in early detection of any problems that might make a difference between good eyesight and blindness.
In a typical examination, an ophthalmologist determines how much a person can see without corrective lenses, and if the need arises tries to improve the vision by selecting suitable option.
The first step involves the assessment of how well both the eyes work together (binocular vision), then he/she will carefully examine the inside and outside of the eyes. He/she will measure the pressure inside and outside of the eyes. Patients above 40 and younger ones that have near relative with glucoma need to get the pressure inside the eye tested.
This will follow checking of the width, or field of the vision and then color vision.
Normal sight is classified as 20/20 which means that you can read letters of a fixed size on a chart at a distance of 20 feet. A measure of 20/32 indicates that you can read a line at 20 feet which another individual with normal vision can read at 32 feet.
