Understanding color vision deficiency (color blindness)

Q: What is color vision deficiency?

Color vision deficiency is a visual condition that affects how some people see colors. It’s typically genetic, and can range from mild to severe, impacting your ability to distinguish between certain colors or color combinations.

Q: How is color vision deficiency diagnosed?

The most common way an eye care professional screens for color vision deficiency is by using images made of colored dots but they may use other more specialized tests to accurately differentiate the type and severity.

Q: Can color vision deficiency be treated?

While inherited color vision deficiency has no cure, your doctor may recommend ways to help manage it, like special glasses or contact lenses, memorization tricks, or even apps to help identify colors.

Q: Why is color vision deficiency more common in men?

Most cases of inherited color vision deficiency are linked to a genetic trait located on the X chromosome. Since males have only one X chromosome, they are more likely to exhibit the condition than females, who may be able to compensate for a defect in one X chromosome if their second X chromosome has a normal gene.

Q: Are there any apps to help with color vision deficiency?

There are various apps designed to help with color vision deficiency. Ask your doctor for a recommendation on which would be the best for you to use.
