Boddities | Episode 5 | Why do bright lights make us see spots?

The video explains why we see spots after looking at bright lights, starting with how vision works. Light passes through the cornea and lens, focusing on photoreceptors that send signals to the brain. Bright flashes overstimulate these photoreceptors, causing afterimages.
