Color blindness occurs when you are unable to see colors in a normal way. It is also known as color deficiency. Color blindness often happens when someone cannot distinguish between certain colors. This usually happens between greens and reds, and occasionally blues.

In the retina, there are two types of cells that detect light. They are called rods and cones. Rods detect only light and dark and are very sensitive to low light levels. Cone cells detect color and are concentrated near the center of your vision. There are three types of cones that see color: red, green and blue. The brain uses input from these cone cells to determine our color perception.

Color blindness can happen when one or more of the color cone cells are absent, not working, or detect a different color than normal. Severe color blindness occurs when all three cone cells are absent. Mild color blindness happens when all three cone cells are present but one cone cell does not work right. It detects a different color than normal.

There are different degrees of color blindness. Some people with mild color deficiencies can see colors normally in good light but have difficulty in dim light. Others cannot distinguish certain colors in any light. The most severe form of color blindness, in which everything is seen in shades of gray, is uncommon. Color blindness usually affects both eyes equally and remains stable throughout life.

Color blindness is usually something that you have from birth but you can also get it later in life. Change in color vision can signify a more serious condition. Anyone who experiences a significant change in color perception should see an ophthalmologist.

Color Blindness Symptoms

The symptoms of color blindness can range from mild to severe. Many people have such mild symptoms that they are unaware that they have a color deficiency. Parents may only notice a problem with a child when he is learning his colors.

The symptoms include:

trouble seeing colors and the brightness of colors in the usual way;

inability to tell the difference between shades of the same or similar colors. This happens most with red and green, or blue and yellow.

Except in the most severe form, color blindness does not affect the sharpness of vision. The inability to see any color at all and to see everything only in shades of gray is called achromatopsia. This rare condition is often associated with:

Causes of Color Blindness

Most people with color blindness are born with it. This is called a congenital condition. Congenital color vision defects usually pass from mother to son.

These defects are due to partial or complete lack of cones in the retina. Cones help you to distinguish the colors red, green, and blue.

Most color vision problems that occur later in life are a result of:

disease

trauma

toxic effects from drugs

metabolic disease, or

vascular disease

Color vision defects from disease are less understood than congenital color vision problems. Disease-specific color blindness often affects both eyes differently. Color vision defect caused by disease usually gets worse over time. Acquired color vision loss can be the result of damage to the retina or optic nerve.

Who Is at Risk for Color Blindness?

Men are at much higher risk for being born with color blindness than women, who seldom have the problem. An estimated one in ten males has some form of color deficiency. Color blindness is more common among men of Northern European descent.

Having certain conditions may increase your risk for acquired color deficiency, including:

Certain drugs may also increase your risk for acquiring color blindness. The drug hydroxychloroquine (Plaquenil) can cause color blindness. It is used to treat rheumatoid arthritis, among other conditions.

Color Blindness Diagnosis

Your ophthalmologist will be able to conduct a simple test to determine if you have color blindness.

The test consists of showing you a pattern made up of multi-colored dots. If you do not have a color deficiency, you will be able to see numbers and shapes among the dots. If you are color blind, you will have a hard time finding the number or shape in the pattern. You may not see anything in the pattern at all.

Color Blindness Treatment

There is no treatment for congenital color blindness. It usually does not cause any significant disability. However, there are special contact lenses and glasses that may help.

Your ophthalmologist can treat acquired forms of color blindness. He or she will address the underlying condition or drug that caused the problem.

What we see is less than meets the eye, especially for those who are color-blind. About ten percent of men are to some degree red-green color-blind. Roughly 1.5 percent of men cannot distinguish reds from greens because they lack either the red- or green-sensitive cone pigments, but for the most part, color blindness results when one of the three types of visual pigments doesn't work normally.

Color blindness is incredibly common, impacting millions of people in the world. Many people have no idea that they are color blind and are not seeing the wide breadth of color that others see. At Clinton Eye Associates, we have been helping residents of Clinton, CT determine whether or not they are colorblind for many years. If you suspect your acre color blind, here's what you need to know.

Who Can Be Color Blind?

Men and women of all ages can be color blind, but the condition is much more common in men than in women. Often, people discover they are color blind when they are children and can adapt to this difference early on. In other cases, people do not realize they are color blind until they are adults.

What Does Color Blindness Involve?

For most people, being color blind means they are unable to see all colors. Some people might struggle to differentiate between different colors when they see them. The two most common types of color blindness are red-green color blindness and blue-yellow color blindness.

Is Your Child Color Blind?

An optometrist is often the first to notice color blindness in children. If you think your child is exhibiting symptoms of color blindness, consult with an optometrist to diagnose the condition. In many cases, color blindness is confused with different types of learning disorders, so having the appropriate knowledge will be helpful. For instance, a teacher who knows your child is color blind may be less likely to use certain types of colors in the classroom. This ensures your child does not miss out on crucial information.

Can Color Blindness Be Cured?

While there is not a cure for color blindness, there are a few options available to help. Some glasses can be used to address some vision issues, but in other cases, building awareness of the issue is the most important thing. With knowledge of the impairment, you can adjust in your life as necessary.

Color blindness, or color vision deficiency (CVD), is typically inherited genetically and carried recessively on the X chromosome. While color blindness is often considered a mild disability, studies estimate that two-thirds of people with CVD feel it's a handicap.
