Comprehensive Information, Resources, and Support on Color Blindness
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.
Your retina is the light-sensitive layer of tissue that lines the inside of your eye. It sends visual messages through the optic nerve to the brain. When the retina detaches, it is lifted from its normal position. This can lead to retinal detachment, if not treated, causing even permanent loss of vision.
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. It consists of a set of colored dotted plates (PseudoIsochromatic Plate or PIP), each of which shows certain numbers or patterns such as random lines.
Photo-pigments in cones help in viewing all possible colors. Any defect in cones lead to color vision deficiency or color blindness. Quantitative tests such as Ishihara test, etc are mainly used to analyze color vision deficiency and color blindness.
Color blindness is a condition in which a person is unable to differentiate between colors. Color blindness is not a form of complete blindness instead it is a deficiency which doesn’t allow a person to see certain specific colors such as yellow and blue or red and green.
