There are two kinds of light receptor in the retina of the human eye. The rod cells work in dim light and do not distinguish colors. The cone cells operate in ordinary light conditions and they distinguish colors. My mnemonic trick to keep the rods and cones straight is to think of several cones of ice cream, naturally of many different colors. Color blindness has to do with the various processes of light perception by the cone cells. But color blindness is a more complex condition than you might think.

How do glasses that simulate color blindness work and what impact do they have on individuals with normal color vision?

Glasses that simulate color blindness work by filtering out specific colors to mimic the experience of color vision deficiency. When individuals with normal color vision wear these glasses, they can better understand and empathize with the challenges faced by those with color blindness. This can lead to increased awareness and sensitivity towards the needs of color blind individuals.
