The Anatomy and Function of the Eye

The video tutorial provides an in-depth look at the structure and function of the human eye. It explains how the eye acts as a sensory receptor, converting light stimuli into electrical impulses for the CNS. The tutorial covers the retina's role, detailing rod and cone cells' functions in light and color detection. It also discusses the pupil and iris's role in regulating light entry, and the cornea and lens's function in refracting and focusing light. The process of focusing on near and distant objects is explained, highlighting the lens's adaptability. The presentation concludes with a labeled diagram of the eye.
