What is color blindness?
Color blindness is a disorder that causes people to loose sight of some colors such as, red, green, blue, and yellow. It is a single gene disorder and was discovered by John Dalton in 1794. It doesn't cause a lower life expectancy. Color blindness is a dominant trait and is passed on from generation to generation.
Doctors have discovered 2 new ways for people with color blindness to either get rid of it or help see the colors that they can't see. First, there is a Ishihara test where the doctor gives the patient a piece of paper with hundreds of dotted colors on it and in the center is either a shape, number, or letter, then the patient has to tell what it is. Another way are the new invention, the EnChroma glasses that help someone with color blindness see the colors that they can't see.
This test has a patient that is color blind of red and green.
This patient that is taking this test is color blind of yellow and blue with some shades of darker colors.
This tests' patient is color blind of blue and purple.
Design of Glasses
When doctors created the EnChroma glasses, they made the light hitting them get turned into the actual colors that the patient is supposed to see. The light from the sun reflects off the glasses into the person's eyes and will make them see the correct colors that the they can't see.
Harm to body/side effects
Color blindness can be a very damaging genetic disorder. If someone inherits color blindness from a parent or relative, they start with it from day 1. Over time as the child begins to grown up and get older their sight of whatever colors they can't see will start to get worse and worse until they won't be able to see other colors as well. Although color blindness can be very harmful to the human eye, it can also help it in some ways too. First, when someone with color blindness and they can't see green and red, most of the time they are able to see other colors like orange and purple. But over time when they get older their whole sight of colors will get messed up, so they will have to wear the color blind glasses to prevent this.
