What Is Color Blindness?
Color blindness, also known as color vision deficiency is a common condition, where you lose the ability to see colors in the traditional way. This usually occurs when cones, a type of nerve cell in your retina, are not working properly. Cones help process images and light as they enter your eyes. They then send the processed information as signals to your brain that allows you to identify colors.
Color blindness does not mean you cannot see every color. In most cases, people with this condition can perceive a wide range of colors. However, they may see some colors better than others do. People with color blindness may also find it difficult to tell the difference between certain colors or shades. Total loss of ability to see colors rarely occurs.
If you or your child finds it difficult to identify certain colors, it is imperative to speak to your doctor. Talk to an ophthalmologist or optometrist to know the type, severity, nature, and effects of the condition.
