A lens, invented by scientists, combines the focusing ability of a human eye with the wide-angle view of an insect eye to capture images with depth. Share: Facebook Twitter Pinterest LinkedIN Email.

Multiplied by 2, we find our total viewing angle. The resolution of our eyes is 12 vertical lines per arc angle (one line per arcminute for 20/20 acuity) times 2. Now 28 degrees x 12 lines x 2 = 672.

For example, the precision-lens manufacturer Zeiss states that its Planar 50-mm lens is “equal to the human eye.” Many artists have taken up 50-mm lenses to render ordinary, everyday experience.
