Simon Jones: Blue light back in business?

I recently came across an interesting article in Forbes on the introduction of safety ratings for computer displays. I say interesting because, as far as I was aware, electronic device manufacturers had got on top of blue light several years ago. Even the old-ish cheap screen I’m looking at while writing this has a ‘Low Blue Light’ sticker.

With a name that sounds reassuring and worrying in equal measures, the Eyesafe 2.0 display standard has been developed by the Eyesafe Vision Health Advisory Board as a result of a ‘growing body of research that demands that more precise indices are needed to differentiate competing low blue light protective measures while adding additional requirements for accurate colour performance and energy displacement.’
