Understanding Your Vision

The human eye is one of the most complex structures found in the body. Your eye is comprised of several parts, but we are primarily concerned here with the cornea, iris, lens, vitreous humor, retina, rods and cones, and optical nerve.

Light is focused through the cornea, the transparent structure at the front of the eye. From there, the iris, a ring shaped membrane with an adjustable opening, expands or contracts to adjust to the amount of light coming through the cornea.

The lens is held into place with cillary muscles. When these muscles relax, they pull on and flatten the lens, allowing objects both far and near to be seen. After light passes through the lens, it passes through a jelly like substance called the vitreous humor. Light must pass through the vitreous humor before it strikes the sensitive area of the retina.

Embedded within the retina are rods and cones – light sensitive cells that convert the light into electrical signals that are related to the brain via the optic nerve. The brain then turns these signals into the image we see. All of this happens, as it were, in the blink of an eye, faster than we can even imagine.

Your eyes are designed to work perfectly, but what do you do when conditions create poor eyesight? Thankfully, the experienced eye doctors at Gailey Eye Clinic are trained in the latest technologies to help you see and feel your best. Contact lenses, glasses, even laser eye surgery are all options for people whose lives are interrupted by poor eyesight.
