Color blindness is when your eyes don’t see colors the way that they are supposed to. Instead, your eyes see a difference in the light rays that hit them. It is similar to the way that you hear different sounds as high or low, which is known as pitch, and it relates to the sound frequency or the number of times it vibrates during a given moment.
The left-side keys on a piano create low-frequency sound, and the further right you go on the piano, the higher the frequency of sound you will create. There is a very comparable order to the colors that you see.
The colors of the rainbow show up in the same order each and every time: red, orange, yellow, green, blue, indigo, and violet. The various colors in the rainbow relate to different wavelengths of light. For instance, bluish colors have a shorter wavelength, while reddish colors have a longer one. Similar to the way there are several notes on a piano, there are several wavelengths of light that match the various colors
Think about your eye like a camera. The front of your eye has a lens, whose role is to concentrate images on the interior of the back of the eye. This particular area is known as the retina. The retina is covered with nerve cells that consist of pigments that respond to the light. These pigments are known as:
If the cones have the different pigments, which are known as photopigments, then your eyes are able to see all the possible colors. Now, if there is a problem with these pigments, you will be unable to see the various colors properly, which is known as color blindness or color deficiency.
In the event that just a single pigment is not present, then you may only have difficulty seeing specific colors. If there are no pigments in your cones, though, then you will not see any color at all, which is referred to as achromatopsia.
As a general rule, genes that are inherited from your mom and dad can result in defective photopigments—molecules that have the ability to distinguish color in the cones, or cone-shaped cells, in your retina. However, in some cases, color blindness is not a result of your genes and instead is due to the following:
The most common kinds occur when genes that you inherit from your mom and dad which help create the photopigments in the cones of your eyes do not properly work. In some cases, this could mean that you are not as sensitive to certain colors, and in other instances, it may mean that you are unable to see specific colors.
It is when photopigments in the red or green cones of your eyes do not work correctly or possibly even at all. There are a few different types, such as the following.
This type of color blindness occurs when the photopigments of your blue cone cells are not working correctly or are missing completely. It is the second most common form of color blindness, and it tends to impact the male and female population equally. There are a couple of different types, including:
Also referred to as monochromacy, you are unable to see any color at all and your overall vision may not be incredibly clear. There are two forms of complete color blindness:
The type of color blindness that is present at birth does not. Most individuals who are considered colorblind are able to lead normal, complete lives. This condition, however, may stop you from having certain careers, such as a pilot, which require a specific level of color vision.
If you believe you have an issue with color vision, reach out to us at Performance Vision Inc. immediately. We can perform an eye examination and let you know if you are seeing colors accurately and what needs to be done in the event that you are not.
