Explaining How Your Brain Controls Your Eye

Many people who are visiting with their eye doctor in Miami want to know just how their brain controls their eyes. The relationship between the brain and the eyes is a complex one, and it’s mainly comprised of electrical signals that get sent back and forth between the two organs. The brain is able to comprehend what the eye sees because of electrical impulses sent to it from the retina, and the eye is able to move and be controlled because of signals sent to the eye from the brain. Eye doctors in Miami will likely tell their patients a little about the relationship between the two, but the complexities of this relationship is something that will take people a lifetime to understand fully.

How the Eyes Interact With the Brain

There are many steps involved in how the brain receives images and electrical signals from the eyes, and they all happen instantaneously. A Miami optometrist can explain a little about how this works when a patient asks them.

● When someone looks at an object, light enters the eye through the cornea.

● The cornea is what’s responsible for refracting light properly. People who have issues with their cornea often need eyeglasses in Miami Beach so they can see correctly.

● Once light passes through the cornea, it enters the pupil. The iris surrounding the pupil controls just how much light is able to enter the eye to prevent damage.

● Light will pass through the vitreous humour, then land on the retina located in the back of the eye.

● The retina is what’s responsible for turning the images into electrical signals, which get transferred to the brain along the optic nerves.

The Brain Controlling the Eyes

The aforementioned steps are how the eyes send signals to the brain, but many people want to know how their brain affects their eyes as well. This is regulated by the muscles that are attached to the eyes. When someone wants to see in a certain direction, they simply look there and the muscles will do the rest. Electrical signals from the brain will tell the eye which direction it’s supposed to move, the same way a person’s arm lifts when they want to reach for something. While this is just a brief overview of how the brain and eyes interact with each other, it should give someone a more clear image of how the relationship between these two vital organs works.
