Use Lasik eye surgery as a permanent way to correct your vision

Posted in Contact Lenses on June 21, 2010

Our eyes are a very important part of our lives. They help us to undergo our normal everyday tasks with ease. We might take our eyes for granted but the thought of living with restricted eyesight can be frightening. In order to understand our eyes and how they work, we must first look at the various parts of the eye.

How does an eye function?

The eye focuses light rays coming from an object toward its retina. Light enters the eye and passes through a thin layer known as the cornea.

The cornea focuses the light on a crystalline lens. The crystalline lens is situated at the back of the eye and focuses the light on the retina. When light falls on the retina, it forms a clear image. This image is then transmitted to the brain with the help of the optic nerve. If the light source does not reach the retina, it may produce an unclear or blurred image. Many common vision problems arise due to the inability of the eye to focus light on the retina.

How can Lasik help?

Lasik eye surgery is used for vision correction and can eliminate the need for glasses or contact lenses. Lasik is performed using a cold laser beam which helps to correct problems with the cornea. These problems are mainly caused due to certain types of refractive errors. Lasik surgery will help you to change the shape of your cornea and resolve any refractive errors.
