Color blindness is a congenital color vision disorder.highly associated with a decrease in quality of life, as well as professional and social challenges.
It is not only inconvenient, it is also embarrassing – maybe you can’t tell your daughter’s blueberry from her red Ferrari.
Color blindness can be a huge challenge for children in school. Often they are criticized by their teachers or bullied by their classmates because of their poor color recognition, which makes them feel isolated and inferior.
Types of color blind
The most common is red-green color blindness. According to the theory of three primary colors, any color in the visible spectrum can be composed of red, green, and blue. If all three primary colors can be recognized as normal, and all three primary colors cannot be recognized, it is called total color blindness. Those who have reduced ability to recognize any color are called color weakness, mainly red weakness and green weakness, and blue and yellow weakness. If there is a primary color that cannot be identified, it is called dichromatic vision, mainly protanopia and deuteranopia.
People with color blindness (weak) are born with no correct color discrimination ability and think that others are the same as themselves, so they cannot consciously have the disease. Many color blindness patients have no abnormal findings in eye examination.
Red-green blindness is divided into 2 types
Protonomaly-This type of color blindness is less sensitive to red light and causes the affected person to be indistinguishable from the same color in the red-green-yellow spectrum
Deutranomaly-reduced sensitivity to green light and is the most common form of colour blindness.
Protanopia –people may confuse:
- Black with many shades of red
- Dark brown with dark green, dark orange and dark red
- Some blues with some reds, purples and dark pinks
- Mid-greens with some oranges
Deuteranopes–people may confuse:
- Mid-reds with mid-greens
- Blue-greens with grey and mid-pinks
- Bright greens with yellows
- Pale pinks with light grey
- Mid-reds with mid-brown
- Light blues with lilac
Tritanopes–most people confuse: light blues with greys, dark purples with black, mid-greens with blues and oranges with reds.
Monochromacy — can see no colour at all and their world like only seeing the world on an old black and white television set.
Treatment of color blindness
Researchers at the University of Hong Kong have developed a nano-coating material and process that can be used in contact lenses to correct color vision.
The working principle of this material is to block the band between the red and green wavelengths and to enhance the red and green wavelengths in order to better distinguish between red and green.
People with red and green defects use this kind of lens. After 1-3 weeks, observe the numbers and the surrounding environment, and the clarity of the colors or numbers seen has been greatly improved and improved.
As a result, this nano-coated lens can improve the color vision of people with color blindness.
Color blind contacts will make your life easier. Get the right contact lense that really fits you! For example, read newspapers without any problem when every thing is green, and enjoy a beautiful landscape painting without any confusion on different shades of green. Imagine enjoying watching all kinds of sports in which color plays an important role like basketball or soccer. You will be able to identify specific objects, such as enemy aircraft or friendly aircraft. Also, you can easily match uniform colors you are issued by your company or by your state department.
