Blue-Yellow color blindness is quite uncommon, and the name is misleading. The condition confuses people’s visions of different shades of blue with green, and some shades of yellow with violet.
Color blindness is generally inherited but can also be acquired. Different types of inherited defects are broken up into three categories: monochromacy, dichromacy and anomalous trichromacy. Monochromacy is a rare condition that prevents people from seeing any types of shades and forces them to live in world full of gray. Anomalous trichromacy, can be inherited but is more often acquired. This condition makes it difficult for people to detect slightly different shades. Dichromacy is broken into two groups: hereditary Tritanopia which is a blue-yellow defect and protanopia & deuteranopia which means red-green color blindness.
Protanopia and deuteranopia can be inherited from relatives who suffer from missing or incorrect visual pigments. It can also be acquired from aging or eye injuries or other eye problems such as glaucoma, macular degeneration, cataracts or diabetic retinopathy.
Many people live for years before discovering they suffer from red green color blindness. Unless it becomes apparent through outside observers or an optometrist, people may not notice they see different shades of red and green.
Pseudoisochromatic plate tests are often used to test color vision. Many industries will test color vision abilities of applicants with these plates before moving them along in the hiring process. These tests will immediately and accurately identify people who suffer from blue-yellow color blindness or red-green color blindness.
Fortunately color blindness correction is available for people ready to see the world in full color. Since 1999, Dr. Thomas Azman has been treating people who suffer from blue-yellow color blindness and red-green color blindness with his ColorCorrection System™. The ColorCorrection System determines the exact wavelength of light of needed for each patient, which is then used to design and prescribe ColorCorrective lenses as eyeglasses or soft contact lenses. Dr. Azman has an astonishing 100 percent success rate with his patients passing the Ishihara Color Plate Test, as well as other color vision tests.
The ColorCorrection System™ has defeated the notion that no color blind treatment exists and has helped people open their eyes to a new world full different shades of color.
