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