Mobile phones have become an indispensable part of our lives and people got addicted to more than anything else. Though they have communication a lot easier and put everything at the fingertips, it surely has become an addiction and people tend to glue to the phones most of the time when they are not in front of the computer or TV.
But, the blue light emitted from mobile phones can be extremely dangerous to the health and at times can damage the skin and eyesight according to chief medical officer Dame Sally Davies. He advises to turn off the mobile phones and tablets before going to bed.
‘There is increasing concern about the impact of computer or smartphone screen use and “blue light” upon human health,’ she said in her annual report in March last year. ‘Research is ongoing and this is an important area of investigation.’
According to the research, Blue light which is also called as High Energy Visible (HEV) light has the shortest wavelength on the spectrum and it has high energy.
According to Romesh Angunawela, a consultant eye surgeon at Moorfields Eye Hospital and co-founder of Ophthalmic Consultants of London, Blue light from the digital devices carry more energy and harms vision eventually.
Though there’s no clear evidence that it could lead to loss of eyesight, spending long hours can lead to digital eye strain. This is characterized by headaches, fatigue, blurred vision, and dry eyes.
