What are the Layers of the Eye?

Answer – The wall of the eye is made up of three layers – an outer fibrous one, a middle vascular one and the innermost photoreceptive one.

Explanation:

The outermost layer of the eye is a fibrous layer which gives it shape and protects what is inside it. It is formed collectively by the sclera (the white of the eye) and the cornea (the clear aperture regulating the amount of light that enters the eye).

The middle layer is vascular, i.e it contains blood vessels. It is called the uvea.

The innermost layer is the retina. The cells in this layer are photoreceptor cells, which means that they are sensitive to light, and nerve cells. The photoreceptor cells register the light entering the eye and the nerve cells convey this information to the brain which interprets it. Thus, the retina is essential for the function of seeing.

These layers of the eye enclose the eyeball.
