The Structure and Function of the Human Eye

The video tutorial explores the structure and function of the human eye. It begins by describing the eye as a sensory receptor sensitive to light intensity and color. The tutorial covers various parts of the eye, including the sclera, cornea, pupil, iris, lens, retina, rods, cones, and optic nerve. Each part's function is explained, such as the sclera's protective role, the cornea's light refraction, and the lens's focus adjustment. The video also discusses how the eye controls light entry through the pupil and iris, emphasizing the importance of protecting the retina from damage. The tutorial concludes with a summary of the eye's mechanisms for vision and light regulation.

What are the two types of light receptor cells found in the retina, and what are their functions?

Why is it important for the eye to control the amount of light entering it?

Describe the reflex action that changes the size of the pupil in response to light intensity.
