What is the white part of the eye called?

The white part of the eye is referred to as the sclera. It is the tough, outer protective layer of the eye that maintains the shape of the eyeball and provides an attachment point for the muscles that move the eye. The sclera is continuous with the cornea at the front of the eye, but while the cornea is transparent and allows light to enter, the sclera is opaque and gives the eye its white appearance.

The ciliary body is a part of the eye located behind the iris that helps control the shape of the lens to focus on objects at various distances, while also producing aqueous humor. The cornea, as mentioned, is the clear, front part of the eye responsible for refracting light. The retina is the light-sensitive layer at the back of the eye that converts light into neural signals sent to the brain. Understanding these distinctions highlights why the sclera is uniquely identified as the white part of the eye.
