Eye check ups
January 1, 2009
Regular eye check up by an ophthalmologist is essential to maintain a good eye sight just as eating healthy is essential for the body.
There are many people who never go through any eye disease through out their lives while there are some who need corrective lenses at some time or the other in their life. Regular eye check up is essential as it can detect an early disease or any problem and thus can prevent it from occurring which can cause an eyesight problem or blindness.
An ophthalmologist finds out about the seeing capacity of a person without the use of corrective lenses, in a typical examination. If the ophthalmologist finds the need of corrective lenses, then he tries to improve the sight by choosing suitable options.
A check up involves two main steps:-
In the first step, the ophthalmologist tries to examine how well the eyes work together or in other words, checks the binocular vision. After that he examines the eye from both inside and outside. By examining the eye from inside and outside, the doctor measures the pressure of the eyes. People who are above 40 or younger, who have a near relative with glaucoma, should get the pressure of the inside eye examined.
The second step will be examining the width of the sight or vision and the color sight.
A normal vision is classed as 20/20. By this we mean that a person can read letter of a certain size on the chart which is 20 feet away. Whereas a measure of 20/32 shows that a person can read a line at a distance of 20 feet which an individual with a normal eye sight can read at 32 feet.
