WHAT CAUSES COLOR BLINDNESS & ITS MAGICAL SURESHOT CURE / TREATMENT?

Color blindness, a condition that is also called Daltonism, is not being able to tell all colors apart. Scientists believe that color blindness is inherited.

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.

What is the main cause of color blindness?

What causes color blindness? The most common kinds of color blindness are genetic, meaning they’re passed down from parents. Color blindness can also happen because of damage to your eye or your brain. And color vision may get worse as you get older — often because of cataracts (cloudy areas in the lens of the eye).

A color-blind man who marries a woman with normal vision will have children with normal vision. But the defect is hidden in the daughters, and they can pass it on to their children. If a color-blind man marries a woman whose father is color-blind, probably half of his children will be color-blind.

Most color-blind persons can see only two basic colors of the rainbow, and they confuse other colors. This kind of color blindness is called dichromat vision.

Most persons with dichromatic vision can see a fairly wide range of yellows and blues. But they tend to confuse reds with greens and some reds or greens with some yellows.

Only a very few persons are truly blind to all colors. They have achromatic vision. Persons with achromatic vision see the world in shades of white, gray and black. For them, it’s like looking at black and white photographs.

More men than women are color blind. More than 4 out of every 100 men are color blind, compared to only about one 1 of every 200 women.

There is no cure for color blindness.

Why can’t colorblind people fly planes?

A pilot that misinterprets lights while flying an approach at night could endanger the safety of their crew, passengers, and people on the ground. The FAA is focused on safety and wants to ensure that pilots can perceive different colors used in aviation operations.

Many animals, including cats, dogs and horses, probably do not see color as we do, the scientists tell us. But the condition is normal in their eyes, and it is not a defect in their vision.

Do colorblind people see blue?

There are different types of color blindness and in extremely rare cases people are unable to see any color at all, but most color blind people are unable to fully ‘see’ red, green or blue light.

Is Color blind a disability?

In the UK society doesn’t generally think of color blindness as a disability, but in most cases color blindness should be considered to be a disability and therefore employers, schools and businesses must treat color blindness in the same way they would any other disability.

Many color blind persons do not realize that their eyesight is defective. They have learned to use the color names that everyone else uses. These persons do not know that they do not see the colors that others see. They may be hampered in their everyday activities and their condition may place them in some danger.

If a color blind person confuses red and green, for example, he may be able to tell traffic signals apart only by their brightness.

Some armed forces do not accept color blind persons for military duty.

Most persons can be easily tested for color blindness. The Hardy Rand Rittler (H R R) and Ishihara tests indicate both the type and the degree of color blindness. In these and similar tests, color triangles, squares and other shapes lie buried in a jumble of dots. These dots vary in both color and intensity. As the person identifies the colored shapes, an examiner can determine his ability to see color.

Another test, the Holmgren test, measures the ability to match colors.

Do color blind glasses work?

So color-blindness glasses don’t “fix” color-blindness, but they can make it easier for people — color-blind or not — to tell colors apart. It should be noted that because there are different types of color-blindness, for some people, these glasses won’t do anything at all.

What colors are difficult for colorblind?

Color combinations to avoid for people with color blindness include:

• Red & green.
• Green & brown.
• Green & blue.
• Blue & gray.
• Blue & purple.
• Green & gray.
• Green & black.

John Dalton, an English chemist, was one of the first to investigate color blindness, and the condition now officially has his name. He was born in 1766 and also formulated the law of partial pressures in gases in 1802. This law states that for an ideal gas, the total pressure of a confined gas mixture equals the sum of the pressure each gas would exert alone in the same volume.

What is the rarest color blindness?

Monochromatism

Monochromatism, or complete colorblindness, is the rarest form of color blindness as it relates to the absence of all three cones. Like their similar properties, dichromatism and anomalous trichromacy have very similar variances.

Diagnosis.

If you have trouble seeing certain colors, your eye doctor can test to see if you have a color deficiency. You’ll likely be given a thorough eye exam and shown specially designed pictures made of colored dots that have numbers or shapes in a different color hidden in them.

If you have a color vision deficiency, you’ll find it difficult or impossible to see some of the patterns in the dots.

Treatment.

There are no treatments for most types of color vision difficulties, unless the color vision problem is related to the use of certain medicines or eye conditions. Discontinuing the medication causing your vision problem or treating the underlying eye disease may result in better color vision.

Wearing a colored filter over eyeglasses or a colored contact lens may enhance your perception of contrast between the confused colors. But such lenses won’t improve your ability to see all colors.

Can color-blind be cured?

There are no treatments for most types of color vision difficulties, unless the color vision problem is related to the use of certain medicines or eye conditions. Discontinuing the medication causing your vision problem or treating the underlying eye disease may result in better color vision.

Potential future treatments

Some rare retinal disorders associated with color deficiency could possibly be modified with gene replacement techniques. These treatments are under study and might become available in the future.
