Here’s a great question…one I never thought about personally, but I do spend a lot of time in front of my computer

I’m probably taking an FAA color vision test called Soda. Currently I spend quite a bit of time online, and I’m wondering if my eye vision (or color perception) could change due to this….?

Color is a property of light that depends on the frequency, not the amplitude of light waves. In most cases, when people talk about light, they are referring to white light. The best example of white light is ordinary sunlight: light that comes from the Sun. Light is a form of electromagnetic radiation: a form of energy carried by waves. The term “electromagnetic radiation” refers to a vast range of energy waves, including gamma rays, X rays, ultraviolet rays, visible light, infrared radiation, microwaves, radar, and radio waves. Of all these forms, only one can be detected by the human eye: visible light. White light and colors are closely related. The word “color” or “colour” actually refers to the light of a particular color, such as red light, yellow light, or blue light. The color of a light beam depends on just one factor: the wavelength of the light. Light can be seen only when it reflects off some object. For example, as we look out across a field, we cannot see beams of light passing through the air, but we can see the green of trees, the brown of fences, and the yellow petals of flowers because of light reflected by these objects.

Color effects occur in many different situations in the natural world. For example, the swirling colors in a soap bubble are produced by interference, a process in which light is reflected from two different surfaces very close to each other. The soap bubble is made of a very thin layer of soap: the inside and outside surfaces are less than a millimeter away from each other. When light strikes the bubble, then, it is reflected from both the outer surface and from the inside surface of the bubble. The two reflected beams of light interfere with each other in such a way that some wavelengths of light are reinforced, while others are canceled out. It is by this mechanism that the colors of the soap bubble are produced.

Color blindness is a condition in which people have mild to severe difficulty identifying colors. Color blind people may not be able to recognize various shades of colors and, in some cases, cannot recognize colors at all. When we say that a person is color blind, we do not mean that he/ she can’t see any color at all. It means that color blind people have trouble in seeing the difference between certain colors. Most color-blind people can’t tell the difference between red and green. To understand what causes color blindness, we need to know about the cones in our eyes. These cones are cells on our retina. We have “red,” “blue,” and “green” cones, which are sensitive to those colors and combinations of them. We need all three types to see colors properly. When our cones don’t work properly, or we don’t have the right combination, our brain doesn’t get the right message about which colors we’re seeing. To someone who’s color-blind, a green leaf might look tan or gray. Color blindness is almost always an inherited which means we get it from our parents. Eye doctors test for color blindness by showing a picture made up of different colored dots. If a person can’t see the picture or number within the dots, he or she may be color-blind. Boys are far more likely to be color-blind.

John Dalton, the son of a weaver, was born into a devoutly religious family. At the age of 12, Dalton began teaching in a Quaker school and developed an interest in science. He was most interested in meteorology and kept a lifelong daily journal of atmospheric conditions for his hometown of Manchester, England. By all accounts, Dalton was not an inspiring teacher, and he was hindered as a researcher by being color-blind. He had only a minimal education and limited finances, but he compensated his deficiencies with meticulous and persistent work habits. Dalton’s daily study of the weather led him to conclude, like Robert Boyle and Isaac Newton before him, that the air was made up of gas particles.

John Dalton, in common with his brother, confused scarlet with green and pink with blue which he himself described in 1794. Dalton supposed that his vitreous humor was tinted blue, selectively absorbing longer wavelengths. He instructed that his eyes should be examined after his death, but the examination revealed that the humors were perfectly clear. Dalton accepted an honorary degree from Oxford dressed in a scarlet robe when wearing a scarlet was prohibited by his Quaker faith as he could not  rationalize the actual color of the robe, due to his color blindness, instead he  saw the ceremonial robe as gray, and had no reason to think that  he was  violating the Quaker doctrine.

Sound Familiar?  Welcome home then, Read on…

1. This site is for raising awareness about the problems color blind people face on a daily basis.

2. This site is for identifying problems out there for colorblind people (For example, you can’t see which button is highlighted in your video/computer game)

3. This site is here for you to rant about the shit you have to deal with when you’re color blind.

Yes, I picked the header color of this site because you aren’t  sure what it is! hahaha.
