What did empododes think about vision?

Empedocles, the ancient Greek philosopher, believed that vision occurs through the interaction of light and the eye. He proposed that objects emit "effluences" or particles that travel to the eye, allowing us to perceive them. This idea was part of his broader philosophical views on the nature of reality, where he integrated concepts of love and strife as fundamental forces in the universe. Overall, Empedocles contributed significantly to early theories of perception and the nature of light.
