Blue light from phones, tablets could accelerate blindness and hurt vision, Un estudio encuentra que

The blue light beaming from smartphones and tablets is changing cells in our eyes that could accelerate blindness, according to a study. Researchers from The University of Toledo studied the impact of blue light — which comes from the sun as well as digital devices — on our eyes.

The study found blue light triggers “toxic” reactions in retinal molecules that sense light and signal the brain. The retinal used by photoreceptors in our eyes is what allows people to see. Results showed blue light helps generate poisonous chemical reactions killing photoreceptors, which cannot be restored once they die off.
