What part of the eye does the cornea cover?

The cornea is the transparent, dome-shaped surface that covers the front part of the eye, helping to protect it and allowing light to enter. It plays a crucial role in focusing vision. The shape and curvature of the cornea help to refract light, which is essential for clear vision. Unlike the rest of the eye, which includes structures such as the lens, iris, and retina, the cornea's primary location is at the very front, covering the iris, pupil, and anterior chamber. This unique position makes it vital in the process of light transmission necessary for sight.
