Eyes and Optical Illusions: The Science of Seeing

The video tutorial explains the structure and function of the human eye, focusing on photoreceptors in the retina, rods and cones, and their roles in vision. It discusses how the brain processes visual information, including the perception of complex shapes and colors. The video also covers protective features of the eye, such as eyelids, eyelashes, and eyebrows. Additionally, it explores optical illusions and how they trick the brain. The tutorial concludes with a review and quiz questions to reinforce learning.
