We have all heard of the expression “curiosity killed the cat.” However, in the realm of the world of humans, curiosity has generally resulted in more positive results. For example, inquisitive scientists have attempted to fully comprehend various processes in nature. Engineers have deconstructed how products work, in order to create improved versions. Likewise, understanding how the human eye functions can better allow us to appreciate the outstanding services of Liberty eye care.

Parts And The Whole

Like an intricate machine, the eye is constructed of several parts, and each part has an important role in the functioning of the whole apparatus. The human eye is approximately the size of a ping-pong ball, and is located 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 a tough material.

Corneas Are Not Corny

Availing of liberty eye care may involve the cornea. This clear dome is located ahead of the eye’s colored portion. The cornea’s job is to help the eye remained focused as light enters the organ. Due to being constructed of a transparent tissue, the cornea is difficult to view.

The Apple Of Our Eye

Gaining knowledge about the iris, pupil, and anterior chamber can also be beneficial if we plan to receive liberty eye care. 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. Consequently, the iris can then control the amount of light that passes through the eye’s pupil. The pupil is the black circle that is located in the middle 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

Next, comprehending about the eye’s rods and cones will allow you to better appreciate your liberty eye care. 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 to function well, than rods need. Cones become most effective when a person’s eye is surrounded by moderate or high amounts of light. Our retinas possess three varieties of cones, with each one being sensitive to either green, red, or blue. With these cones we can sense a mix of light waves that allow us to view millions of colors! Understanding how these cones and rods work, can allow you to fully understand the tests that you undergo via liberty eye 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.

Humans are inquisitive by nature. Thus, by fully comprehending how the eye functions, we can better appreciate and understand liberty eye care that we receive.
