Researchers warn that blindness will soon become widespread in the world. 

The related vision impairment mainly occurs due to working long hours in front of a computer, according to Oane.

Blindness will turn into an “epidemic,” in parallel with the spreading of computers, said research team leader Celia Sánchez-Ramos.

Researchers note that most people will suffer from visual impairment in the near future.

According to their studies, LED monitors and screens cause the most serious respective damage.
