What is color blindness?
Color blindness should not be mistaken with blindness. It is simply the inability to differentiate between certain colors such as blue and yellow or red and green.

Studies have shown that about 7 % of all men suffer from color blindness and only about 0.4- 1% of all women experience colorblindness. The chance of colorblindness in women is less, but more number of women can be carriers of the faulty gene that leads to colorblindness.
Colorblindness is often an inherited condition but if we specifically look for blue yellow colorblindness, more cases are occur as a result of non-genetic factors. It is a rare condition and is estimated to occur in about 1 in 30-50,000 persons.

Scientists are now able to grow human retinal cells in the lab. This is a big atempt to understand the basis of color vision in humans and to understand color blindness and other retinal disorders. The research is believed to help develop future therapies for eye disorders such as color blindness or macular degeneration, diabetic retinopathy, age-related damage etc.
Dr Shinobu Ishihara from Japan introduced the most popularly known color blindness test in 1917. The test is a color perception test for red-green color deficiencies.
