Rods and cones Rod cells are the most sensitive cells in your retina. They let you see in very low light.However, they can't tell different colors apart. Cone cells handle color vision. There are three types of cone cells, One type absorbs blue ligh...
In a similar way human beings have favorite colors, too. Yet we are lucky. We can see many beautiful colors in the day because of the cones in our eyes, and with the help of the rods we can see shapes at night. One day we may even learn more about the invisible(看不见的) ...
The colored light enters the eye through the pupil, goes through the lens, then reaches the back of the eye called the retina. On the retina there are a bunch of light sensors called rods and cones. These rods and cones send a signal to the brain about what the eye is seeing. The c...
The operation of the eye is largely muscular and any excessive activity will tire it out. Note: Some scientists have noted that after-images are caused by a depletion of certain chemicals in the rods and cones of the eye, which are sensory cells, not muscles. Here are some practical exampl...
In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of cones in our eyes, we can see many beautiful colors by day, and with the aid of rods we can see shapes at night. One day we may even learn more about the invisible colors around us. 1. ...
Our eyes have two kinds ofspecialized light receptors (rods and cones) located in the retina in the back layer of the eye to help us see.Rodsallow us to see in low light conditions, like at night.Conesallow us to see in bright light, like during the day—and convert light into color...

The inhabitants of Syria and Palestine today delight in brilliant colors. Bright yellow, crimson, magenta and green are used for adornment with no evident sense of fitness, according to the foreigners' eyes, other than their correspondence with the glaring brightness of the eastern skies. A soap...
Isaac Newton was the first to understand thespectrum of light. He refracted white light through a prism in order to see its component colors. Our understanding of color today runs through Newton’s work with light. Cones are the part of the human eye that detect color. Rods are sensitive ...
With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of the rods we can see shapes at night.(1).2. Some people say it's safer to be driven by women because A.women drive more carefully B.women are better at driving than men C....
