The human eye is very complex, containing several different parts that do different jobs which allow us to see. Identifying the ways these parts work together and understanding how the eye works can be very beneficial in helping you to realize if there is ever an issue with your eye. You’ll be able to explain your symptoms more appropriately to your doctor.
Below are the main parts that make up the eye
Below is the eye’s process and how the different parts work together to allow you to see images.
Light reflects off of objects and enter the eye.
When light rays enter the eye, they enter through the cornea which is the clear front of your eye. The cornea bends the light and allows it to pass through the pupil, which is the opening in the center of the iris.
The iris determines how much light enters the eye by enlarging and shrinking.
After the light passes through the iris, light rays then reach the lens. The lens then works like a camera and focuses the light rays properly. After the lens brings the image into sharp focus, it’s sent to the receiving area at the back of the eye called the retina.
The retina is a membrane full of photoreceptors, or rods and cones, that convert the light rays into electrical impulses, which then travel through the optic nerve at the back of the eye, then to the brain. Then the brain perceives the image.
Sometimes, certain parts don’t function correctly and the process doesn’t follow this structure. In those cases, the eye has a refractive error, a disease or a condition, or is damaged in some way.
