Color Blindness Information and Treatment

Color Blindness is a common enough condition which is generally congenital. Congenital colour blindness may be total or partial. Color blindness is the general term used by most people but maybe in this politically correct world we should refer to it as chromatically challenged. However in reality the symptoms range from an inability to see one color, or shades of one color, to a lack of ability to see any color at all. Because it is a result of a cone defect, colorblind people are also prone to night blindness, and may have extreme difficulty in seeing in low light, or their color perception may be greatly reduced in low light. The commonest colours that cannot be distinguished are red and green. It is probably due to the absence of photo pigments normally found.

Colour blindness is a source of danger in professions like sailing the high seas, engine drivers etc. Color blindness may be partial (affecting only some colors), or complete (affecting all colors).  Complete color blindness is very rare.  Those who are completely color blind often have other serious eye problems as well.

COLOURED VISION

Red vision occurs particularly after a cataract operation if the eye is exposed to a bright light.a Objects look red but the vision is not affected. There is no permanent damage. Some color blind people tend to gravitate to bright, vivid colors because they can be detected more easily. Muted colors or low intensity colors (text, lines or bands where there isn't enough color to register) cause difficulty or are indistinguishable.

DARK CIRCLES UNDER EYES

While dark circles could be familiar, however, in a person who has never had dark circles, this could mean trouble. The skin under the eye is very thin and blood passes through veins close to the surface giving a bluish tint in fair skinned individuals. In dark skinned people this tint is not all that visible. However, dark circles when they develop, do show up. These dark circles are due to a higher than normal amount of pigmentation in this area.

Again in dark skinned individuals who fall ill because of a simple common cold, fever, and sniffles, the paleness of the surrounding area accentuates dark circles. Anemia, menstruation, early pregnancy, loss of weight, thyroid disease, tuberculosis and a host of diseases can result in dark circles under the eyes.

Signs and Symptoms of Color Blindness

The symptoms of color blindness are dependent on several factors, such as whether the problem is congenital, acquired, partial, or complete.  

  • Difficulty distinguishing reds and greens (most common)

  • Difficulty distinguishing blues and greens (less common)

The symptoms of more serious inherited color vision problems and some types acquired problems may include:

  • Objects appear as various shades of gray (this occurs with complete color blindness and is very rare)

  • Reduced vision

  • Nystagmus

Treatment of Color Blindness

1. Do consult a doctor to rule out any major disease.

2. Improve diet intake. Avoid junk food.

3. Drink sufficient fluids.

4. Cut down on smoking and drinking

5. Avoid late nights (very important).

6. Do exercise regularly
