Color blindness – or more precisely, poor or impaired color vision – is an inability to tell the difference between certain colors. Although many people frequently use the term “color blindness” to refer to this condition, true color blindness – where everything is seen in black and white – is rare.
- Color blindness is usually inherited. Men are more likely to be born with color blindness. Most color-blind people cannot distinguish between certain reds and greens. More rarely, color-blind people cannot distinguish between shades of blue and yellow.Deficient color vision(Color blindness) treatment hyderabad

The reasons
Seeing colors across the spectrum of light is a complex process that begins with your eyes’ ability to respond to different wavelengths of light.
The light, which contains all wavelengths of color, enters your eye through the cornea and passes through the lens and the transparent gelatin tissue of your eye (vitreous) to wavelength-sensitive cells (cones) in the fundus in the macular area of the retina. Cones are sensitive to short (blue), medium (green) or long (red) wavelengths of light. The chemicals in the cones trigger a reaction and send the wavelength information to your brain via your optic nerve.
Color blindness has several causes:
Hereditary disease. Hereditary color deficiencies are far more common in men than in women. The most common color deficiency is red-green, with blue-yellow deficiency being much rarer. It is rare not to have color vision.
You can inherit a mild, moderate, or severe degree of the disease. Inherited color deficiencies usually affect both eyes and their severity will not change over the course of your life.
Diseases. Some conditions that can cause color deficits are sickle cell anemia, diabetes, macular degeneration, Alzheimer’s disease, multiple sclerosis, glaucoma, Parkinson’s disease, chronic alcoholism, and leukemia. One eye can be more affected than the other, and the color deficit can improve if the underlying condition can be treated.
Certain drugs. Certain medications can affect color vision, such as: B. Certain medications that treat certain autoimmune diseases, heart problems, high blood pressure, erectile dysfunction, infections, nervous disorders, and psychological problems.
Aging. Your ability to see colors slowly deteriorates as you age.
Chemicals. Exposure to certain chemicals in the workplace such as carbon disulfide and fertilizers can lead to loss of color vision.Deficient color vision(Color blindness) treatment hyderabad
