Understanding Color Blindness and Vision

The video discusses the misconceptions around the term 'color blindness' and explains how the human eye detects color using cone cells. It covers various types of color vision deficiencies, their genetic causes, and the sex-linked nature of red-green color blindness. The video also highlights scientific advances in curing color blindness, such as gene therapy, and explores assistive technologies like tinted lenses and special glasses. It concludes with fun facts, including the reason behind Facebook's blue color choice.
