Color blindness happens when the eye’s color-sensing pigments make it hard or impossible to tell different colors apart.
Yellows and blues may also be difficult to distinguish, although this type of color blindness is less common, and most colorblind people have trouble telling red from green.
Symptoms of Color Blindness
Some people discover they or their child has color vision deficiency when it causes confusion, such as when there are issues interpreting color-coded learning materials or being able to distinguish the colors in a traffic light.
Color blindness can prevent some people from being able to tell the difference between:
- red and green in various tones
- various hues of yellow and blue
- Any colors
A person with a red-green or blue-yellow deficiency is typically not completely insensitive to both colors. Defects can be mild, moderate, or severe. The most prevalent color deficiency is an inability to see some shades of red and green.
Causes of Color Blindness
Your eyes’ capacity to react to various light wavelengths is the first step in the intricate process of seeing colors across the light spectrum.
The cones are wavelength-sensitive cells (cones) at the back of the eye in the macular area of the retina. The cones are sensitive to short (blue), medium (green), or long (red) wavelengths of light. Chemicals in the cones trigger a reaction and send the wavelength information through optic nerve to the brain. Light enters the eye through the cornea, passes through the lens and transparent, jellylike tissue in the eye (vitreous humor).
There are several reasons why someone might be color blind:
Inherited disorder.Males are much more likely than females to have inherited color deficiencies, with red-green deficiency being the most prevalent and blue-yellow deficiency being much less so. It is uncommon to have no color vision at all.
The severity of inherited color deficiencies doesn’t change over the course of a person’s lifetime, and it can be mild, moderate, or severe.
Diseases.One eye may be more affected than the other, and the color deficit may improve if the underlying disease can be treated, including sickle cell anemia, diabetes, macular degeneration, Alzheimer’s disease, multiple sclerosis, glaucoma, Parkinson’s disease, chronic alcoholism, and leukemia.
Certain medications.Some medicines, including those used to treat some autoimmune diseases, heart conditions, high blood pressure, erectile dysfunction, infections, nervous system disorders, and psychological issues, can affect how you perceive color.
Aging.Age gradually affects one’s capacity for color vision.
Chemicals.Loss of color vision may result from exposure to certain chemicals at work, including fertilizers and carbon disulfide.
HOMOEOPATHIC TREATMENT OF COLOR BLINDNESS
- Agaricus mus:Deception in color and difficulty reading
- Belladona:blinking of the eyes causes red objects to appear yellow.
- Digitalis:Blue and yellow have a white appearance.
- Gratiola off:Green object appear white
- Phosphorus:The condition of color blindness is typically curable with a good remedy, etc.
