Most visual problems are caused by the way the eye refracts (or bends) light, and then focuses the light rays. During an eye examination, the doctor considers how the parts of your eye impact your vision, including the overall shape of your eyeball, the cornea, the power of the natural lens, and the actual length of your eye.

The eye is spherical structure about an inch in diameter. It works in a manner similar to that of a camera. Each individual function of the eye plays a vital role in providing you clear vision.
The iris (the colored portion of the eye), act as the shutter to regulate the amount of light entering the eye. The cornea and the lens, located behind the pupil, focuses the light rays from the object onto the retina at the back of the eye. The retina then transmits the ‘picture’ of the object to the macula. It is here the optic nerve collects and transmits the images to the brain.

Refractive conditions are caused by an imperfectly shaped eyeball, cornea or lens: |

We treat short and long-sighted people including those with astigmatism. Although we can only clearly assess if you are suitable for laser vision correction through a no-obligation consultation at our clinic, here are some facts about refractive conditions. |
