The Senses. Researchers have studied vision more thoroughly than the other senses. Because people need sight to perform most daily activities, the sense of sight has evolved to be highly sophisticated. Vision, however, would not exist without the presence of light. Light is electromagnetic radiation that travels in the form of waves. Light is emitted from the sun, stars, fire, and lightbulbs. Most other objects just reflect light. People experience light as having three features: color, brightness, and saturation.
Blindness is the inability to see anything, even light. If youâre partially blind, you have limited vision. For example, you may have blurry vision or the inability to distinguish the shapes of objects. Complete blindness means that you canât see at all and are in total darkness. Legal blindness refers to vision thatâs highly compromised. What a person with healthy eyes can see from 200 feet away a legally blind person can see only from 20 feet away.
