All about Eye: Rod & Cone (Photoreceptor cells)
|Description||The rods and cones in our eyes help us see! The rods enable us to see in low light while the cones enable us to see in color. There are three types of cones: the S-cones (short-wavelength sensitive cones), the M-cones (middle-wavelength sensitive cones), and the L-cones (long-wavelength sensitive cones).|
|Name||The rods are rod-shaped while the cones are cone-shaped.|
|Actual Size||A rod cell is about 2 microns in diameter and 100 microns long. A cone cell is about .5 to 4 microns in diameter and 40 to 50 microns long.|
|System||Retina of the eye|
|Quantity||There are around 120 million rods and 6 to 7 million cones in our eyes!|
|Fascinating Facts||Color blindness occurs when the cones, which are responsible for color vision, are not sensitive or totally absent. The most common type of color blindness is red green color blindness!
Colorblind people may only be able to differentiate 20 hues of color whereas non-colorblind people can differentiate 100 hues of color.
Human beings are more colorblind than pigeons.
There are more colorblind males than females.
