What eye structure gives the shape of the eye?

The shape of the eye is primarily determined by the sclera, which is the white outer layer of the eyeball. This tough, fibrous structure provides support and maintains the eye's spherical shape. Additionally, the cornea, the transparent front part of the eye, contributes to its overall curvature and refractive properties, helping to focus light onto the retina. Together, these structures play a crucial role in maintaining the eye's shape and function.
