There may be a perception that color blindness is an unusual condition that doesn't affect the general population much. There is a surprising 8% male and 0.5% female prevalence of the disorder. You don't have to do the math to figure out this means 1 out of every 200 women and 1 out of every 12 men! Some other color blindness facts might surprise you as well. Check if you have a color vision deficiency by taking our free color blind test.
1. Mark Zuckerberg Is Colorblind
Facebook CEO Mark Zuckerberg suffers from red-green colorblindness. Thus, blue was the best color for him to see. The Facebook website and mobile app are dominated by blue because of this reason. Can you imagine what Facebook's color scheme would look like if he wasn't colorblind?
2. Newly Born Babies Are Color Blind
A newborn baby is colorblind until 7 days after birth when they begin to see colors. They begin to develop functional color vision at about 6 years of age.
3. Color Blindness Is Usually Genetic.
4. Colored Contact Lenses
The majority of people with color blindness don't require treatment and function well. Specially formulated contact lenses can help you distinguish different colors, but they don’t make your vision normal and might distort objects.
Other times, glare-blocking sunglasses may be required. People with significant color blindness may be able to distinguish particular colors better when there is less brightness. Some people are able to gather location hints simply by looking around. As an example, they might memorize the order of the colors on traffic lights.
5. It’s Not All Black and White.
The majority of people who are considered color blind are able to see some colors. A color deficient individual is a color blind individual who is unable to distinguish between black, white, and shades of gray. People with color deficiency see a limited spectrum that is not always accurate.
Color blindness is generally split into three main categories: red-green color blindness (most common), blue-yellow color blindness, and total color blindness (rare).
These categories are further separated into sub-categories which determine severity. Mild cases of color deficiency can lead to embarrassing wardrobe mishaps or mistakes identifying colors outside the usual spectrum. Severe cases can affect school and work performance, health, and important safety issues.
6. It’s Not Easy to Recognize.
Color deficiency is sometimes diagnosed years after problems have been occurring. The American Academy of Ophthalmology has no formal requirements for colorblind testing. When a child sees things the same way he always has, it’s impossible for him to know it’s different than what others see.
Most children can detect some colors and can learn to guess different hues. When the same colors are missed over and over, it can be mistaken for a learning difficulty similar to confusing a lowercase ‘b’ for ‘d’ or writing a certain number backward. A noticeable symptom might be when a child places markedly different colors together during a sorting activity.
If the condition goes undiagnosed, the child soon learns to read the names of colors and follow other students in color-related activities. In their early school years, color-deficient students report some daily difficulties. No diagnosis before the middle school could lead to a potential disaster during science lab.

7. Color Deficiency Could Be the Reason Your Child Is a Picky Eater.
Would you be able to enjoy a creamy glob of peanut butter if it was green? If ripe and green bananas looked the same, we might not like them so much. If cooked spinach was a dull shade of brown, it could look like a juicy pile of something else on your plate.
Many color-deficient people couldn’t tell the difference between chocolate syrup and ketchup without a label. It might be easy to say we’d still love the foods we always have, but, to a child who hasn’t acquired a taste for things, the appearance can be too much to overcome.

8. Traffic Lights Are The Wrong Colors.
Red-green color blindness is by far the most common type. People with a mild deficiency can often detect the colors of traffic lights. However, a severe color deficiency makes all lights appear white, similar to streetlights.
Colorblind sufferers quickly learn to consider light order (red on top, green at the bottom) during the daytime. However, response times are significantly slowed. By dusk, placement is almost impossible to discern, increasing the potential for error.
Perhaps, the question of brake lights is equally dangerous. At speeds of over 45 miles per hour, the bright red glare of brake lights is the best indication of a car suddenly slowing ahead. Brake lights are barely noticeable to a person with severe color deficiency.
The patient would probably have to spend so much time focusing on brake lights to see the change, and they would miss other dangers on the road.

9. There Are Treatments Available.
While there is no cure for genetic color blindness, solutions do exist. The most well-known products include a variety of lenses and glasses, many of which work to varying effectiveness.
Most health insurance policies also do not recognize the problem as a medical condition, adding to the cost.
Otherwise, there is hope for a cure in the future with gene therapy. This solution is a ways off but currently undergoing testing and clinical trials.
The medical community has long recognized color deficiency as a problem. Multiple studies have been conducted, enabling the court to observe its share of cases regarding disability and the workplace.
Nearsightedness is a condition routinely checked by your eye doctor, often covered by vision plans on health insurance and noted on our driver’s licenses. Color blindness may be treated similarly soon.
