How the Eye Works
With easy to understand explanations of some of the most common vision problems, you can see how laser vision correction can transform the way you look at the world.
Your eye works much in the same way as a camera. Light rays enter the eye through the cornea like a camera lens. The cornea serves a dual function of both protecting the eye as well as refracting the light to pass through the pupil and onto the retina, affecting how sharp the “picture” appears to your eye. The pupil and iris act as an aperture — the part of the camera that determines the amount of light to which the film is exposed. Like a zoom button, the eye’s lens changes in order to focus on objects depending on their distance. Finally, the retina acts like the camera’s film, capturing the information the eye sees.
