There are millions of them in our eye’s retina—special photoreceptor cells known as rods and cones that allow us to perceive a wide range of light intensities and colors. "There is a critical need to ...

What's the retinal resolution of the human eye, or how many pixels can we actually perceive? And is there any point in ...

Scientists have created a new platform called 'Oz' that uses laser light to control up to 1,000 photoreceptors in the eye at once. Using Oz, the researchers showed people images, videos and a new, ...

A team of scientists believes they have discovered a new color outside the range of human vision. They named the color “olo” and describe it as an “unprecedented,” ultra-saturated, bluish-green. The ...

Humans rely on sight, which is primarily mediated by three color-sensing cone types, to perceive the world in a kaleidoscope of hues. Blue cones develop earliest, followed by the morphologically ...

As artificial intelligence and smart devices continue to evolve, machine vision is taking an increasingly pivotal role as a key enabler of modern technologies. Unfortunately, despite much progress, ...

Color is more than a sensory pleasure; it is a tool refined by evolution. Our ability to perceive a broad spectrum of hues is a remarkable biological achievement shaped by survival pressures, social ...

A new experiment into color vision has allowed a select group of human subjects to see a new color. Subjects describe the “unprecedented” color as a very saturated teal. Researchers are looking into ...
