what are rods and cones and its differences
Answers
Rods and cones are the two types of photoreceptors in the human retina. Rods and cones are essential for vision. Rods and cones together are able to detect movement, light and colour, and relay that information back to the brain.
Rods: Rods are highly sensitive cells located in the outer area of the retina (the lining of the back of the eye). They are used in areas of dim light and are most acute to light, shape and movement changes. Rods do not detect colour. Rods help people to see in low light.
Cones: Cones are located in the central fovea (central area of the retina). They are less sensitive than rods and require bright lighting. Cones are central to our ability to see colour. Cones help people see colours and have depth perception
