A Glimpse of Color Blindness

by Dr. Leon F. Cohn Eye Specialist
Color is the characteristic of visual perception, which derives the stimulation from photoreceptor cells in organisms, For example, cone cells in human beings are responsible for the visualization of colors. For some of us are not able to see colors, this does not mean that they are blind. Color blindness or color vision deficiency is the decreased ability of a person to differentiate among colors. A color-blind person is usually unable to distinguish between red, blue, and green colors. Generally, color blindness runs in families. For most people, it’s not a big issue as they can comfortably adapt to it. So what a color-blind person sees may not be the same as everyone.

Causes:

We can see different colors because of the three types of cones present in our eyes, but in some people, these cone cells are faulty and do not perform correctly, making their color vision blind. Color blindness is generally a genetic problem. It means it is hereditary also and can pass from generation to generation. Men are more prone to this problem as the color blindness gene is present on the X chromosome, which is mainly carried by men. But this can also be caused by any damage or trauma to the eye or brain. And this condition worsens with growing age and senility. Certain diseases like diabetes, multiple sclerosis, Alzheimer’s, glaucoma, cataract can also cause color vision blindness. Sometimes color blindness is also present as a degenerative disease and is triggered by diabetes and vitamin A deficiency.

Types of color vision blindness:

The most common type of color blindness is difficulty in differentiating between red and green color. Then there is blue and yellow color blindness, which is rare comparatively. And then there is complete color blindness, which is very uncommon. In the severe type of color blindness, everything looks white, black, and gray.

Diagnosis:

Generally, if a person is color vision blind, he can self detect it as it will be very tough for him to be able to tell exact colors. Lab tests or imaging is not required. A therapist can diagnose it by presenting the patient with a circle full of colorful dots and do the color blind test Florida. For people with perfectly fine eyes, it will be trouble-free. Whereas, it will give a hard time for a color-blind person to differentiate between them.

Signs and symptoms:

The main symptom of color blindness is that the person will not be able to see the colors as a normal person does. He will be unable to differentiate among various colors, their brightness, and what are the different shades. Generally, the symptoms are very mild.

Treatment:

Usually, genetic color blindness is non-curable as it is a chromosomal malformation and is hereditable. But for those color blindness, which is due to some other health problems, a cure can be done. The ophthalmologist plantation fl or eye doctor plantation fl can cure the underlying factors causing the problem.

Some medicines can cause color blindness if consumed without consideration. Generally, color blindness does not cause any serious issues, but still, there are some devices and technology that can help. Also, there is a color correction system, which can help with color-blind vision and can be worn both indoors and outdoors. This practice is followed in topmost color vision testing Florida. Customized filters are designed to fit into patients eyeglasses Special contact glasses and spectacles can help. One can use visual aids or technology also.

So, in the end, we can say that color blindness runs in families. But this is not a thing to worry about. One must get it checked timely. And also, take measures to prevent it if the cause is some other factor.
