Most of the time, color blindness makes it hard to tell the difference between certain colors. Usually, color blindness runs in families. There's no cure, but special glasses and contact lenses can help. Most people who are color blind are able to adjust and don't have problems with everyday activities.

Is color blindness lifelong?

Inherited color blindness is a lifelong challenge. While it may limit prospects for certain jobs, such as working as an electrician who must tell the difference between color-coded wires, most people find ways to adapt to the condition.

Why there is no cure for color blindness?

There is no cure for inherited color blindness. But scientists have shown that placing certain color-recognizing (photopigment) genes into eye cells of male monkeys known to be red-green color-blind allows the animals to tell the difference between the two colors.
