Anatomy

Your eye is round and made of three main layers that form the eyeball. The eye’s function is to let you see, capturing images like a camera and turning them into data that it sends through the optic nerve to the brain, where it is translated back into images.

The eye has three main layers:

• Sclera: The outer layer of the eyeball is a tough, white, opaque membrane called the (the white of the eye).


• Choroid: The middle layer is the choroid. The front of the choroid is the colored part of the eye called the iris


• Retina: The inner layer consisting of two layers:
• Sensory retina, containing the nerve cells that process visual information and send it to the brain


• Retinal pigment epithelium (RPE), the layer between the sensory retina and the wall of the eye

To maintain optimal eye health, make sure you see an optometrist regularly, protect your eyes from the sun, and keep your prescription up to date if you wear corrective lenses.
