Color Blindness - Topic Overview
How is it treated?
Inherited color vision problems
cannot be treated or corrected.
For the most common type of color blindness—red-green color deficiency—no treatment is needed, because you function normally. You may not be aware that you do not see colors the way they are seen by others.
Some acquired color vision
problems can be treated, depending on the cause. For example, if a cataract is
causing a problem with color vision, surgery to remove the cataract may restore
normal color vision.
You can find ways to help make up for a color
vision problem, such as:
- Wearing colored contact lenses. These may help you see differences between colors. But these lenses don't
provide normal color vision and can distort objects.
- Wearing glasses that block glare. People with severe
color vision problems can see differences between colors better when there is
less glare and brightness.
- Learning to look for cues like brightness or location, rather than colors. For example, you can learn the
order of the three colored lights on a traffic signal.
How can you help a child who has color blindness?
Color vision problems may make it harder for children to learn and read, which
can lead to poor schoolwork and low self-esteem.
You can help your
child these ways.
- Make sure your child is tested for color
vision problems during routine eye tests. The sooner you know there is a
problem, the sooner you can help your child. Eye exams should be done at all well-child visits.1
- Tell your child's
teachers and other school staff about the problem. This may be helpful. Suggest seating your child
where there is no glare and using a color of chalk that your child can see.
