Colour blindness

Colour blindness (colour blindness) is a reduced ability to detect colour or colour difference.  It can interfere with activities such as picking ripe fruit, choosing clothing and learning about traffic lights. Colour blindness can make some educational activities more difficult.

In most cases, color defects are caused by a genetic defect in the child. This is because some color-sensitive cells in the eyes, called cones, are lost or misaligned.
