Researchers have harnessed the human eye's color-sensing strengths to give the eye the ability to distinguish between objects that differ in thickness by no more than a few nanometers, about the width ...

For years, machines have navigated the world color-blind. LiDAR sensors – the laser-based eyes of self-driving cars, ...

Two male squirrel monkeys now see the world in a whole new way — in full color. Female squirrel monkeys can see in color, but male squirrel monkeys are normally red-green colorblind because they lack ...

Color blindness is a condition where people find it difficult to distinguish between certain colors. This color blindness test is a simple eye test to find out whether or not you are color blind.

The shift from warm summer to cool fall conditions can be stressful for many animals. Surviving each season requires a multitude of different physiological and behavioral traits that scientists are ...

Scientists have studied color vision by probing individual sensory cells in the human eye. The results confirm that the photoreceptor cells of the retina are especially sensitive to colors ...

This story is part of a series on the current progression in Regenerative Medicine. This piece is part of a series dedicated to the eye and improvements in restoring vision. In 1999, I defined ...

Zachary Lehr has trouble distinguishing some colors. The 6-year-old has a mild form of color blindness, a condition that affects 5 to 10 percent of the U.S. population, according to National ...

Our ability to see with color vision depends on the presence and function of light-sensing pigments in the cones of our eyes. Color blindness, or color vision deficiency, happens when one or more of ...
