Not to freak you out or anything, but the lights from your smartphone could be even more harmful than experts previously thought.
We already knew that the blue light from your smartphones, tablets, and laptops can disrupt your sleep cycle. Recently, a study found a connection between blue light and breast and prostate cancer. Noe there’s more bad news.
Nearly half of smartphone users spend more than 5 hours on their device every day. 47% of smartphone users spend at least 5 hours on their device daily, according to a survey from Counterpoint Research. 26% of them spend 7 hours or more.
In a newly established study, researchers from the University of Toledo found that blue light triggers a chemical reaction in retinal molecules that kills photoreceptor cells.
So what does this mean? basically blue light could damage your vision or even accelerate blindness. Photoreceptor cells don’t grow back – once they’re gone, they’re gone.
Just to be safe, you might want to put your iPhone in Night Shift mode or use an app like f.lux on your computer to filter blue light at night. You could also try shutting your electronics down and hour or two before bed.
