Treatments

There’s no cure for color vision deficiency that’s passed down in families (inherited). If color vision deficiency is causing problems with everyday tasks they are available options, like:

- Glasses and contacts : They work by increasing the contrast between colors so they’re easier to tell apart.

- Visual aids : Apps let people take photos with a phone or tablet and then tap on part of the photo to find out what color it is.

Dangers

Because of their inability to distinguish red from green, color-blind men can have trouble recognizing blood in their bodily fluids. They are less likely than others to spot blood in photographs of sputum, urine, or stool. In theory, this could delay the diagnosis of a dangerous malignancy.

Diagnoses

The Ishihara test is the most common test eye care providers use to diagnose red-green color blindness. Some plates include numbers that you can only see with full-color vision. Others include numbers that you can only see with color vision deficiency. The test we gave you at the beginning is an example.If you believe you may have color blindness, contact an eye care provider to schedule an eye exam. Or take a better test online (view link)

Origin

The genes responsible for red and green sensitivity are located on the X chromosome, while the one for blue is on chromosome 7.
