Understanding Retinal Fatigue

The video tutorial explores the concept of retinal fatigue, likening the eyes to muscles that tire with overuse. It explains how photoreceptors, specifically rods and cones, can become fatigued, leading to afterimages. These afterimages are optical illusions of complementary colors. The video includes experiments demonstrating this phenomenon and introduces the opponent process theory, which explains how the human eye processes color through receptor complexes. This theory accounts for the perception of afterimages in complementary colors.

What is the opponent process theory of color vision?

Why can't our eyes process certain color complexes at the same time?

How do complementary colors relate to the afterimages we see?
