Frogs have maintained a surprising diversity of light-sensing proteins over evolutionary time, according to a new study led by a Penn State researcher. Light-sensing proteins, called opsins, enable ...

Vision is a complex process that has been successfully deciphered by many disciplines—physics, biochemistry, physiology, neurology, etc.: The retina captures light, the optic nerve transmits ...

Conventional silicon architecture has taken computer vision a long way, but Purdue University researchers are developing an alternative path — taking a cue from nature — that they say is the ...

An assortment of animals active after dark have evolved remarkable night vision, giving them a clear advantage when the sun goes down. Their eyes are often larger in proportion to their heads, with ...

Astigmatism is an eye condition that causes blurry vision, especially in dim light. That's because astigmatism occurs when the eye is shaped more like an oval than a sphere, which distorts the light ...

New research from the University of Waikato nails down how much light travels from the outside world to babies in the womb, with far-reaching implications for understanding human development. Research ...
