How Eyes Work

Correcting refractive errors

A normal eye functions rather like a camera. The cornea is the clear window at the front of the eye. Along with the natural lens inside the eye, the cornea should focus light coming from a distance clearly on to the retina at the back of the eye.

The retina contains millions of tiny receptors which convert light into electrical impulses to be carried by the optic nerve to the brain.

The iris (coloured part of the eye) acts like the aperture of the camera, regulating the amount of light getting in.

An eye in which the light from a distance is not focused correctly on the retina, has what we call a refractive error.

To have clear vision you basically need all the optical planets aligned, which for a lot of us doesn’t happen. If light rays entering the eye are not precisely focused by both the cornea and the lens and then processed by the retina, you end up with blurred vision.

Lions Laser Vision has treatments to correct many types of refractive errors that cause blurred vision. Click here to see our treatment options for common eye problems.
