Symptoms of color blindness can vary from person to person, depending on the degree of color blindness. Sometimes, people with partial color blindness cannot see some solid colors like red or green or brown. They may see these colors as grey or black.
If the color vision problem is not of severe nature, then you may not even realize that you have it. People, who have lesser degree of color vision problem, can see lesser variations of colors. If you consistently see shades of white, grey and black only, then you may have color blindness.
Color blindness is mostly an inherited condition. A color vision problem that has been acquired can change over period of time and become less or more. A color vision problem is not identified naturally at birth. Only when a person grows up to be old enough to understand different colors and is unable to identify, it is brought to notice. Usually kids are identified with this problem during their pre-school years when they are learning about colors. The difficulty to identify colors is clearly seen in this age group. An eye specialist will conduct a special test to see if the child has color blindness.
Unfortunately, there is no cure for color blindness. There is no way one can correct the vision to identify colors even through surgery. Color blindness can occur as a result of complete defect in the eye, or it can occur due to a defect in the brain. A defect in the brain, or problems with color identification can be cured through therapy.
