Attoseconds, the billionths of a billionth of a second, are the shortest flashes of light ever created. Now, scientists have figured out how to focus them. A team from the Max Born Institute (MBI) in ...

The US Food and Drug Administration has approved a new system for nerve repair based on light-activated polymers rather than surgical stitches. The flexible polymer system was developed by the medical ...

Dr. Greg Moloney, MBBS, BSC MED, MMED, FRCSC, Ophthalmologist, explains what cataracts are and how they are corrected with intraocular lens surgery (IOL). Was Trump’s Venezuelan boat attack a ‘war ...

Infrared light passes through the metal lens and is converted into violet light and focused in a focal point due to the material and the special surface structures – enlarged in the magnifying glass.

The cameras in modern mobile phones are so small and powerful that NASA chose them for its recent Mars Ingenuity Helicopter rather than spending money on improving the technology. Nonetheless, the ...

A study participant puts in a contact lens. Researchers developed lenses with nanoparticles that convert infrared wavelengths into visible light that humans can perceive. Yuqian Ma, Yunuo Chen, Hang ...

Contact lenses have enabled people to see beyond the visible light range, picking up flickers of infrared light even in the dark – or with their eyes closed. The lenses contain engineered ...

Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision ...
