Liberty Eye Care Vision Plan
An Insight Into Your Eyes

Knowing how the human eye functions and the problems we can encounter with our eyesight is very important. Liberty Eye and Vision Care is an organization committed to helping us protect our eyesight. The Liberty Eye Care Vision Plan is a very extensive plan that affords great protection. Compliments of Liberty Eye Care we share with you some important facts about the eye.

Parts And The Whole

The eye, like an intricate machine is made up of several parts. Each part has an important role in the functioning of the eye as a whole organ. A human eye is approximately the size of a table tennis ball, and rests in a cavity known as the skull’s eye socket. The white portion of the eyeball is referred to as the schlera. This part, which covers the majority of the eyeball, is composed of tough material.

Corneas Are Not Corny

The cornea is a clear dome located on the eye’s colored portion. The cornea’s job is to help the eye remain focused as light enters the organ. Because the cornea is made from a transparent tissue it is difficult to see.

The Apple Of Our Eye

Other parts of the eye are the iris, pupil, and anterior chamber. These parts of the eye are located behind the cornea. The iris, known as the “apple of the eye,” is the part of the eye that provides its color. Muscles attached to the iris alter its form. As a consequence the iris then controls the amount of light that passes through the eye’s pupil.

The pupil is the black circle that is located in the center of the iris. In fact, this is a gap in the iris that allows light to pass through. Pupils become smaller as light shines nearby, and then become wider with the absence of light.

Rods and Cones

The eye’s retina utilizes special cells, termed as cones and rods, in order to handle light. Incredibly, the human eye has about 7 million cones and 120 million rods in each eye! Rods are extremely sensitive, and see in white, gray, and black. They inform us about the shape or form of an object.

On the other hand, cones can perceive color, and require a higher amount of light than rods in order that they can function well. Cones become most effective when a person’s eye is surrounded by moderate or high amounts of external light. Our retinas possess three varieties of cones, with each one being sensitive to the colors green, red, or blue. With these cones we can sense a mix of light waves that allow us to view millions of different color shades and hues! Understanding how these cones and rods work, can allow you to fully understand the tests that you undergo via Liberty Eye and Vision Care.

The Fastest Messenger

Lastly, the optic nerve functions like a messenger from the eye, to the brain. The retina’s rods and cones alter the images and colors that we view, into millions of “messages” that are contained in nerves. The optic nerve then sends those messages to the brain – like an ultra-fast Internet connection. When you see an object, your optic nerve then “reports” to the brain what it is viewing, so the brain can then translate it into an object that we recognize.
