Color blindness, also known as color vision deficiency, is a medical condition characterized by the inability to perceive specific colors that most people typically see.
People with this condition may be unable to distinguish between certain colors, or they may only see similar shades of colors different from people with normal color vision.
A person with color blindness is usually not aware that they have a problem with color vision until they are tested. The most common type of color blindness is inherited, which means it is passed down from parents to children.
In most cases, color blindness affects both eyes equally. Sometimes, only one eye may be affected. There are different degrees of color blindness, ranging from mild to severe.
Some people with color blindness can only see shades of gray, while others may have trouble distinguishing between certain colors, green and red. Most people with color blindness can adapt and live normal lives. There is no cure for color blindness, but special contact lenses or glasses can help some people cope with the condition.
