WebMar 10, 2024 · These cells function by sensing light and/or color and delivering the message back to the brain through the optic nerve. While cone photoreceptors detect color through bright light, rod photoreceptors are sensitive to low-light levels. Rods aid in night vision and identifying black and white hues. WebYour retina is made up of light-sensitive cells which send messages to your brain about what you see. Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot.

http://www.changingminds.org/explanations/perception/visual/light_detection_eye.htm WebOnce the light is in our eye it passes through fluids and lands on the retina at the back of the eye. The retina turns the light rays into signals that our brain can understand. The retina uses light sensitive cells called rods and cones to see. The rods are extra sensitive to light and help us to see when it's dark. The cones help us to see color.

WebLight travels into the eye to the retina, located on the back of the eye. The retina is covered with millions of light receptive cells called rods and cones.
