Causes of Color Blindness
Color blindness is usually genetic. Many more men are color blind than women. This is because the color blind cell is in the X chromosome, which the mother always gives to her kid(s). The mother is called “the carrier,” because she carries the X chromosome to her kid(s). The mother who gives the color blind gene to her kid(s) is usually not color blind herself.
Medications and drugs can also lead to color blindness. Some of these medications are antibiotics, barbitutes, anti-tuberculosis drugs, high blood pressure medications, and some variations of nervous disorder medications.
The last thing that causes color blindness can occur because of diseases like diabetes, and almost every form of eye disease. Glaucoma, cataracts, optic nerve disease, and macular degeneration. All different kinds of eye diseases. Color blindness, no matter what the cause, should never get worse. It should not get better either without special treatments.
The retina (a thin layer of tissue covering the inner surface of the eye) of an eye has two parts: cone cells, and rods. Rods help your eye adjust to darkness, and to bright lights. The cones cells let you see different colors. There are three different kinds of cone cells; one type sees blue light, the second type sees green lights, and the third kind of cone cell sees red light.
That is what causes color blindness, and color blindness’s effects.
