Color blindness is when an individual is unable to differentiate between some colors. This is due to a genetic mutation that affects in the retina of the eye. There are a higher percentage of men diagnosed with color blindness than women. This is because the X chromosome holds the gene for color blindness, and men only need one X chromosome to carry the gene for them to get the condition where as women need two. Women are usually the carriers of the condition, but do not experience color blindness themselves. Color blindness could start from birth or it could only be clearly visible at childhood or adulthood. Color blindness can affect daily tasks, like choosing clothes to wear, looking at traffic lights, cooking and telling whether the meat is cooked, etc.
The retina of the eye contains two types of light-sensitive cells called cones and rods. The rods and cones are photoreceptors that transfer visual signals to the brain from the eye. Cones are less sensitive to light than rods and mostly work in bright light. Cones are more sensitive to colors. The eye has three types of cones: red, blue, and green. Each cone has a unique pigment that allows it to receive a specific wavelength of light. Normal color vision is seen when the brain incorporates all that was received from each cone.
There are three types of inherited color blindness: monochromacy, dichromacy, and anomalous trichromacy. Monochromacy is a type of color blindness where one has no cones to recognize colors and therefore can’t see any colors. A person with monochromatic vision would only see a variety of shades of grey. Dichromacy vision limits a person to only have two of the three cones working well. There are three types of dichromatic vision: deuteranopia, pr...

People can find out which type of color blindness they have by taking a color test. There are many different types of these color tests. The most well known and common tests is the Ishihara test which displays a bunch of colored spots on the screen that show a number, and if the person can’t see that number or sees a different number then the person is colorblind. And if they continue on with the test they can eventually find out what type they are. There is no way to treat and get rid of color blindness genetically, but there are other remedies. Some treatments include corrective lenses, which helps by changing the wavelength of certain colors that reach your eye. There are also devices that one puts in their ear and the device tells them the color being seen. Also there are mobile and other apps to assist.
