Straight out of science fiction, these contact lenses convert infrared light into visible light that humans can see ...

Combining regular lens technology with nanoparticles, researchers have created prototypes of contact lenses that allow people ...

All the parts of the eye work together to allow vision. They take in light from the environment and send visual information for the brain to process. Here is a summary of how the visual system ...

But even in the presence of just a few light particles, special cells in our eyes activate. For decades researchers have been trying to find out the minimum number of photons our eyes can see.

most of our digital devices have a lot of visible blue light,” said Scott Edmonds, chief eye care officer at UnitedHealthcare. “This blue light, we believe, is going to build up in a long ...

There are cheaper and more effective ways to salvage your eyes from all that screen time. By Dani Blum The pitch for blue-light-filtering glasses is compelling: an easy way to counteract that ...

The sun or bright indoor light can be uncomfortable, even painful. Photophobia is linked to the connection between cells in your eyes that detect light and a nerve that goes to your head.

Blue light has shorter wavelengths and higher energy than other colors. Some research shows a link between eye damage and short-wave blue light with wavelengths between 415 and 455 nanometers.

Eyes are testaments to evolution’s creativity. They all do the same basic things—detect light, and convert it into electrical signals—but in such a wondrous variety of ways. There are single ...
