AP PSYCHOLOGY

Detailed explanation-1: -On the front surface of the eye is the see-through, circle-shaped cornea. You can’t see a person’s cornea the way you can see the colored part of the eye behind it-the cornea is like a clear window that focuses light into the eye.

Detailed explanation-2: -Lens: The lens is a clear part of the eye behind the iris that helps to focus light and images on the retina.

Detailed explanation-3: -Cornea: the transparent circular part of the front of the eyeball. It refracts the light entering the eye onto the lens, which then focuses it onto the retina. The cornea contains no blood vessels and is extremely sensitive to pain.

Detailed explanation-4: -Cornea. Like the glass on a watch, the cornea is the clear protective coating on the front of the eye that allows light to pass through it without distortion. It covers the colored iris. The lens of the eye focuses the images transmitted through the cornea to the retina.

Detailed explanation-5: -The cornea is a transparent outer covering of the front of the eye. It protects the eye and also acts as a convex lens. A convex lens is thicker in the middle than at the edges and makes rays of light converge, or meet at a point. The shape of the cornea helps focus light that enters the eye.
