Detailed explanation-1: -The human eye is a sense organ adapted to allow vision by reacting to light. The eye contains structures that allow it to perceive light, movement and colour differences. The eye is our collector of light, giving us sight. Its delicate structures enable entering light energy to be converted to electrochemical energy.
Detailed explanation-2: -Sight. The third sense is sight (also known as vision), and is created by your brain and a pair of sensory organs-your eyes. Vision is often thought of as the strongest of the senses. That’s because humans tend to rely more on sight, rather than hearing or smell, for information about their environment.
Detailed explanation-3: -The organs that respond to these senses are called sense organs. Our sense organs are the eyes, ears, nose, tongue and skin.
