For the first time, a new study has revealed how and when we make eye contact—not just the act itself—plays a crucial role in ...

Each year, more than 30 million people globally receive surgery to correct cataracts. As many people age, the crystalline ...

UK company Superdielectrics says its polymer technology could make batteries cheaper and easier to recycle, but its energy ...

Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

For example, scientists have used this effect to create contact lenses that allow people to see in the dark. The light from a laser pointer starts out as invisible infrared light, then passes through ...

A team of scientists from China have created contact lenses that can help people to see in the dark. These new lenses allow people to see infrared light, which is normally invisible to the human eye.

Chinese scientists have developed infrared contact lenses that allow humans to see in the dark by converting invisible infrared light into visible light.

To create the contact lenses, the team combined the nanoparticles with flexible, non-toxic polymers that are used in standard soft contact lenses. After showing that the contact lenses were non-toxic, ...

The lenses allow "people to see beyond the visible light range, picking up flickers of infrared light even in the dark — or with their eyes closed," said New Scientist.

Night-vision goggles can let you see infrared light in green, but these contacts let you see it in green, blue, and red wavelengths.
