Understanding Color Blindness: Symptoms and Solutions

Woman having her eyes examined - Understanding Color Blindness: Symptoms and Solutions

Living with color blindness

Imagine picking our produce at the grocery, watching a sunset, or choosing an outfit. These commonplace activities can present unique challenges for people who suffer from color blindness. You probably are so used to the way you see certain colors you may not even think about how it could be different for others. However, being color blind comes with many unexpected difficulties, surprises, and frustrations that you probably never even considered.   

Color blindness, otherwise known as Color Vision Deficiency (CVD), is actually quite common, as 1 out of every 12 men is diagnosed with some form of color deficiency. Many people don’t even realize they have this condition and need to be tested. 

If you or someone you know is color blind, there are some everyday experiences that may be more difficult. Small tasks, such as identifying the difference between ripe and unripe fruits and vegetables, choosing complementary colors for outfits, and even playing or watching certain sports, present a unique set of challenges for those who are color blind   

Currently, there is no cure for this condition. Yet, we offer some treatments at VisionFirst to help with some of these difficulties.  

Before sharing how we can help, we’d like to give you more info about color blindness and what symptoms to look for.

Color blindness in children 

Color blindness can be especially challenging for children, as they may not even realize they are color blind, leading to some difficulties in the classroom. For parents and teachers, it is crucial to become more aware of the symptoms of color blindness, as it may be possible to recognize and respond to the particular challenges faced by children with color vision deficiency. 

Some common indicators that a child may be experiencing color vision deficiency are:

If you believe your child is exhibiting symptoms of color blindness, it is easy to get them tested by scheduling an appointment at VisionFirst. The sooner we identify color blindness, the easier it is to find ways to help them. If your child is diagnosed with color blindness, it is essential to communicate this information with their teachers, as well, as minor adjustments in the classroom can make a big difference.

What is color blindness? 

Color blindness, or Color Vision Deficiency, is “an inability to see the difference between certain colors.” 

Despite its name, color blindness doesn’t mean that you can’t see color—you just don’t see color in the usual way. Color blindness happens when the cone cells in your eyes, used to detect colors, are either absent or working improperly. Those with normal color vision have three types of cones—red, green, and blue. However, if you have color vision deficiency, one of these cones does not work correctly and detects a different color than normal. Severe color deficiency happens when all three cones are absent.

“Light, which contains all color wavelengths, enters your eye through the cornea and passes through the lens and transparent, jellylike tissue in your eye (vitreous humor) to wavelength-sensitive cells (cones) at the back of your eye in the macular area of the retina. The cones are sensitive to short (blue), medium (green) or long (red) wavelengths of light. Chemicals in the cones trigger a reaction and send the wavelength information through your optic nerve to your brain.

If your eyes are normal, you perceive color. But if your cones lack one or more wavelength-sensitive chemicals, you will be unable to distinguish the colors red, green or blue.”

Though there are different degrees of color blindness, the most common is the difficulty to distinguish between shades of red and green. Additionally, a small number of people can’t distinguish shades of blue and yellow. The most severe form of color blindness, where everything is seen in shades of gray, is uncommon.

Symptoms of color blindness could include difficulty seeing: 

Even within these symptoms, there are varying degrees of color blindness that can affect your eyes. Sometimes, those with more mild cases of color vision deficiency may still see colors in good lighting conditions, while those with more severe cases cannot distinguish certain colors, regardless of lighting conditions. Monochromacy is when you don’t see colors at all, which is very rare.

What causes color blindness? 

Typically, color blindness is genetic and inherited from one’s parents at birth. Statistically, more men are impacted by color blindness than women. Yet, many who are color blind may be unaware of having this eye deficiency. 

Though color vision deficiency is typically something you have from birth, it can sometimes show up later in life. Below are some causes of color blindness that occurs later in life:

Solutions for color blindness—one lens at a time

Missing out on shades of red, green, blue, or even yellow doesn’t have to be permanent. With a simple change in glasses, color blindness can become practically obsolete.
