Blue light from dig­i­tal de­vices in­clud­ing smart­phones could ac­cel­er­ate blind­ness, re­searchers have found. Ac­cord­ing to a re­search by the Univer­sity of Toledo in the US, ex­po­sure to blue light con­tin­u­ously might cause poi­sonous mol­e­cules to be gen­er­ated in the eye’s light-sen­si­tive cells and lead to mac­u­lar de­gen­er­a­tion, Xin­hua news agency re­ported last fort­night. As one of the lead­ing causes of blind­ness in the US, mac­u­lar de­gen­er­a­tion does not lead to to­tal blind­ness, but can make daily ac­tiv­i­ties dif­fi­cult.

“It’s no se­cret that blue light harms our vi­sion by dam­ag­ing the eye’s retina. 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,” said Ajith Karunarathne, an as­sis­tant pro­fes­sor in the univer­sity’s de­part­ment of chem­istry and bio­chem­istry.
