The white part of the eye is formed by which tissue?

Explanation:
The eye’s white area is formed by the sclera, a tough outer fibrous layer. This dense connective tissue protects the eyeball, maintains its shape, and provides attachment for the extraocular muscles that move the eye. It’s opaque and sturdy, which is why you see the white sclera around the colored iris. In contrast, the cornea at the front is clear to let light in, the iris is the colored part that controls pupil size, and the retina lines the back inside of the eye and contains light-detecting cells. So, the white part is the sclera because it is the opaque protective coat that gives the eye its white appearance.
