Understanding Color Blindness: Causes and Effects

The video explains that color blindness is not seeing the world in black and white but involves difficulty in distinguishing certain colors, primarily red, green, or blue. It is mostly genetic and remains stable throughout life. The eye's rods and cones play a crucial role in color vision, with cones responsible for color discrimination. Color blindness occurs when one type of cone cell malfunctions, leading to difficulty in perceiving certain colors. The most common type is red-green color blindness. Non-genetic causes include aging, eye problems, or medication side effects.
