The occurrence and function of light-sensing pigments in our eyes' cones are required for colour vision. Color blindness, also known as colour vision deficiency, occurs when one or more of these cones fails to function. Protanopia is a condition in which the red cones are absent, leaving only the cones that capture blue and green light. It is important to visit the eye doctor in Rajkot for immediate checkup as it can cause major problems in future. Aadhya Eye Hospital cares for your eye.
