What are the light detecting parts of the eye?
The retina is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones.
What are the parts of the eye and what do they do?
The cornea, a clear window at the front of the eye, covers the iris and the pupil. A clear lens, located behind the pupil, acts like a camera lens by focusing light onto the retina at the back of the eye. The retina is a light-sensitive inner lining at the back of the eye.
How many parts are in the eye?

Do cones detect color?
The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors. Most people have three kinds of cone cells.

What are the visual components of the eye?
In addition to the retina, other visual components such as the pupil, iris (colored part of the eye), and lens help focus light rays on the retina. The retina is the light-sensitive membrane covering the back of the eye. When light entering the eye hits the retina, special cells known as photoreceptors convert it into electrical signals. 1
