Blue light from phone screens accelerates blindness, study finds-World Hot Events
Light from digital devices triggers
creation of toxic molecule in the retina that can cause macular degeneration
Scientists say they have found how
blue light from smartphones, laptops and other digital devices damages vision
and can speed up blindness.
Research by the University of Toledo
in the US has revealed that prolonged
exposure to blue light triggers poisonous molecules to be generated in the eye’s light-sensitive cells that can cause macular degeneration – an incurable condition that affects the middle part of vision.

Blue light, which has a shorter
wavelength and more energy compared with other colours, can gradually cause
damage to the eyes.
