Eye and Vision

1.2.1 Photopic Vision

The cones of the rentina (7 millions in number) are responsible for day vision, in three dimensions and in colour, three different photopigments giving sensitivity to red, blue and green.

1.2.2 Scotopic Vision

The rods of the rentina (130 millions in number) are responsible for night vision.

1.2.3 Mesopic Vision

Mescopic vision applies to luminance range from about 10-2 to about 10 cd/m2, where neither of photopic and scotopic vision is dominant.
