Blue light from mobile phones and computers can cause irreversible damage to eyes: Scientific Reports study

- Blue light from devices such as smartphones and computers can cause irreversible damage to the eyes, a study in the United States has found.

The study, which was published in July by researchers from the University of Toledo (UT) in Ohio, found that blue light from digital devices could cause diseases such as loss of central vision and night blindness.

One of the researchers of the project, Dr Ajith Karunarathne, told the UT website that humans are continuously exposed to blue light because the eye's cornea and lens cannot block or reflect it.

"It's no secret that blue light harms our vision by damaging the eye's retina," she said.

"Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop."

The study was published in Scientific Reports, a free online journal from the publishers of Nature. Nature is a science journal that was first published in 1869.
