Binocular Vision Quotes & Sayings

The spiraling flights of moths appear haphazard only because of the mechanisms of olfactory tracking are so different from our own. Using binocular vision, we judge the location of an object by comparing the images from two eyes and tracking directly toward the stimulus. But for species relying on the sense of smell, the organism compares points in space, moves in the direction of the greater concentration, then compares two more points successively, moving in zigzags toward the source. Using olfactory navigation the moth detects currents of scent in the air and, by small increments, discovers how to move upstream. — Barbara Kingsolver

Our earliest ancestors were descended from primates who thrived for millions of years in a treetop environment, and who in the process had evolved one of the most remarkable visual systems in nature. To move quickly and efficiently in such a world, they developed extremely sophisticated eye and muscle coordination. Their eyes slowly evolved into a full-frontal position on the face, giving them binocular, stereoscopic vision. This system provides the brain a highly accurate three-dimensional and detailed perspective, but is rather narrow. Animals that possess such vision - as opposed to eyes on the side or half side - are generally efficient predators like owls or cats. They use this powerful sight to home in on prey in the distance. Tree-living primates evolved this vision for a different purpose - to navigate branches, and to spot fruits, berries, and insects with greater effectiveness. They also evolved elaborate color vision. — Robert Greene

Scarlett activated the viola and it came down like short shimmering curtain that covered her eyes with a band of violet light. It dilated her eyes, increasing her binocular summation so that everything in her field of vision was magnified and clear. It also protected her retinas from any sort of laser fire or plasma flash. — April Adams

Cat. No doubled vision: it's a cat, singular. A solitary diurnal ambush hunter with good hearing and binocular vision and a predilection for biting the neck of its prey in half while disemboweling it with the scythe-like claws on its hind legs. Basically it's a velociraptor with a fur coat and an outsize sense of entitlement. Right — Charles Stross

When I started using the extreme short depth of field and single point of focus, I was trying to replicate my changing eyesight. We have binocular vision; one eye perceives space from the other. I don't experience a scene visually at F32. It's more like F1.4. — Keith Carter
