Nagornyy COLOUR BLINDNESS

  • Also known as colour deficiency
  • Inability to see colours in the normal way
  • Individuals often cannot distinguish between certain colours — usually greens and reds, and sometimes blues as well

PROCESS –

  • Two types of cells in the retina detect light — the “rods”, which distinguish between light and dark, and the “cones” that detect colour
  • There are three types of cones that see colour — red, green, and blue — and our brains use the information from these cells to perceive colour.

REASON

  • Absence of one or more of cone cells, or their failure to work properly
  • In a situation where all three cone cells are present but one of them is malfunctioning, mild colour blindness may occur
