PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -There are two types of photoreceptors: rods and cones. Rods are responsible for peripheral vision, and are located outside of the central part of the retina. There are some 120 million of them, and they are responsible for night vision, because they are highly sensitive to low-intensity light.

Detailed explanation-2: -They detect low levels of light and makeup what is called our scotopic vision (cones make up our photopic vision). While cones give us more detailed information, rods are by far more sensitive. Rods are the reason you can see shapes in low levels of light and are responsible for our peripheral vision.

Detailed explanation-3: -While the visual acuity or visual resolution is much better with the cones, the rods are better motion sensors. Since the rods predominate in the peripheral vision, that peripheral vision is more light sensitive, enabling you to see dimmer objects in your peripheral vision.

Detailed explanation-4: -The main location of cones is in the center of the eye in the macula. Rods are responsible for vision in dim or dark light. They are located on the outer edges of the retina and help with peripheral (side) vision. Rods don’t provide color vision, so night vision is only in black and white.
