The iris is formed of pigmented fibers
The cornea is the cover
Light enters the cornea then goes through the pupil. Depending on the amount of light, the iris dilates the pupil. Light passes through the lens and refracts, converging onto the retina.

In the eye, there are approximately 125 million photoreceptors
