The eye is composed of three primary layers: the fibrous layer, the vascular layer, and the inner layer.
Fibrous Layer: This outermost layer includes the cornea and the sclera. The cornea is transparent and allows light to enter the eye, while the sclera provides structural support and protection. Vascular Layer: Also known as the uvea, this middle layer includes the choroid, the ciliary body, and the iris. It supplies blood to the eye and controls the amount of light that enters. Inner Layer: The innermost layer is the retina, which contains photoreceptor cells that convert light into electrical signals processed by the brain.
