2.The retina of eyes has two types of light sensitive cell rod and cone, due to disorder of these cell color blindness takes place
Color blindness, also known as a color vision problem, is the inability to see red, green, blue, or any mix of these colors. The majority of people who are colorblind inherited this condition from their parents, and is present at birth.
The human eye has three types of cone cells, with each one sensing red, green, or blue light. These cones are found in the macula, which is connected to the main part of the retina.
For those who inherit color blindness, typically, either one of these cone cells are not working properly, or simply ceases to exist. A person will either not see one of the three basic colors (red, blue, or green), or, may see a different shade of that specific color.
However, color blindness is not always inherited. Other causes of color blindness can also be caused from a variety of vision problems, including:
1.Macular degeneration, diabetic retinopathy, glaucoma, or cataracts
2.Injury to the eye
3.Aging
