What are the three main layers of the eye?

The three main layers of the eye are the sclera, choroid coat, and retina.

The sclera is the tough, outer layer of the eye that provides structure and protection. It is often referred to as the "white" of the eye. The choroid coat is located between the sclera and the retina and is mainly responsible for supplying blood to the eye, as it contains many blood vessels. The retina, on the innermost layer, contains photoreceptor cells (rods and cones) that detect light and convert it into neural signals, which the brain then interprets as images.

This layered structure is crucial for the eye's function, allowing it to maintain its shape, facilitate light entry, and process visual information. Understanding these layers helps in appreciating how various parts of the eye contribute to overall vision and health.
