How Do Eyes Work

While we normally take you deeper in terms of the power of LASIK and vision correction, it’s very important to have a good grasp of the fundamentals. You may not be familiar with exactly how your eyes function.

To help you better understand, here’s a quick overview:

It all begins with light rays, which reflect off objects and then enter the eyes through the cornea. Here, the light rays are bent and sent through the lens, where more bending helps to focus the light rays on the retina—giving you the miracle of clear sight.

Cornea – This clear, dome-shaped covering in the front of the eye acts as the eye’s outer lens. Much like a window, the cornea controls light entering the eye. It also helps the eye focus.

Iris & Pupil – The iris is the colored part of the eye that controls how much light goes through the pupil.

Lens – This clear structure focuses light rays onto the retina.

Vitreous Humour – The transparent, jelly-like substance that fills the gap between the lens and the retina.

Retina – This nerve layer lines the back of the eye. The retina takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.

Optic Nerve – This bundle of over a million nerve fibers carries electrical signals from the retina to the brain to be translated into the image that we see.

With both a basic and deeper understanding of your eyes and how they work, we hope you can take care of them better.
