Reasons for color blindness

If you can not distinguish blue and yellow or red and green, or sometimes other people may correct the color you see, you probably have color blindness. Color blindness is neither a form of blindness nor a full range of color disability. People with color blindness usually lack the ability to see certain colors properly. This is just a form of vision deficiency.

Those two types of color deficiencies have different inherit traits: red-green deficiency is found only on men and blue-yellow one affects men and women equally. Health problems such cataract may lead to color blindness. Once you have symptoms described above, you should go to see a doctor for a color blindness testing, which can determine the exact type.

There are mainly two reasons for color blindness: generic inheritance and various diseases, all of which affect the way that the retina’s light-sensitive cells respond to light with different wavelengths. Inherited forms of color blindness are the majority, such as Leber’s hereditary optic neuropathy (LHON) and Kallman’s syndrome. LHON is always associated with red-green color defects, while the Kallman’s syndrome involves failure of the pituitary gland.

Disease-caused color blindness only accounts for a small portion. Cataracts can make the lens less bright, which caused color blindness. An IOL is usually used as a treatment. Parkinson’s disease (PD) and Tiagabine (an antiepileptic drug) are also reported to cause color blindness.

A disappointing fact is that color blindness can not be cured, so that many people with acquired color blindness are forced to discard their jobs that require accurate color perception. Those professions include graphic design and electric wiring. Individuals who are diagnosed with color blindness early enough in life will always choose a career that is less dependent on color perception.

However, there are strategies to make compensation. School-aged children should be given special care in learning if they have color blindness. For example, their teachers can plan particular lessons and presentations that require less color perception. Certain ECPs offer special lenses that can enhance color perception, which are available in both contacts and eyeglasses. Another way to “recognize” the color of clothes for people with color blindness involves organizing and labeling them. Color disabled individuals should also remember the order of different traffic lights.
