The video explores the nature of light and vision, starting with ancient Greek theories that light originates from the eyes. Alhazen's theory corrected this by showing that eyes collect light. Newton proposed light as particles, but later experiments revealed light's wave properties, leading to the understanding of interference patterns. In the 20th century, quantum mechanics introduced the dual nature of light, behaving as both particles and waves.
