Color blindness is always misunderstood as a problem wherein a person cannot see any color. This is completely false. The people who suffer from color blindness have color vision deficiency and are unable to see certain shades of color. Around 8% of men and 0.5% of women suffer from this problem. Let’s take a look at color blindness in more detail.
What is Color Blindness?
Color blindness, also known as color vision deficiency (CVD), is the inability of a human eye to see different colors and its shades. There are three main types of color blindness - red/green which if followed by blue/yellow and then total color blindness. The third type is very rare. Red/green color blindness is the most common problem experienced. People with this type can mostly see the objects placed in front clearly, but can’t see the red, green, and blue light. If this problem advances, it can affect the entire color spectrum of the eye. Eventually, the person can face difficulty with red, green, purple, orange, brown, pink and grey colors. He might also confuse black with dark green or dark blue.
Causes of Color Blindness
There are three cones (red, green, and blue) in the eye that work together so that you can see the whole spectrum of colors. When any of these cones become faulty, you are not able to see the shades of that particular color. This causes color blindness.
Although there are many causes for these cones to get affected, genetic is the most common one. Some other reasons include diabetes, multiple sclerosis, liver diseases and other eye diseases.
Treating with Color Blind Glasses
The wavelength of the light reaching the different cones overlap causing color blindness. The color-blind glass uses a filter to correct these overlapping wavelengths. This helps the patient to get a clear view of the colors in front. Like all other glasses made for different sight problems, these glasses are also not made to completely corrector treat the problem of color blindness in any person. These glasses help the light to reach correctly at the desired cones and hence, giving a better understanding of color.
Going through a comprehensive eye exam will help you understand your eye health better. Based on the result, the optometrist will consult you the right color blindness treatment. Also, if you are facing the color blindness issue because of diabetes, liver problems or other problems, treating the base cause will help you get rid of color blindness.
