You may have heard that blue light that emits from phones and other electronics can disrupt your regular sleep patterns. Now, researchers at the University of Toledo have discovered an entirely new problem with blue light. Apparently, blue light can cause blindness.
Yes, you read that right.
It turns out that retinal, which are molecules we need to see, turn into “cell killers” when it’s exposed to blue light, according to WTOL. This was revealed when researchers studied what happened when blue light was shone onto different types of cells from the body. They looked at photoreceptor cells, neurons, and heart cells. Blue light shone on the retinal lead to poisonous chemicals being produced, which killed photoreceptor cells.
Futurism noted that scientists already knew that blue light from screens “contributed” to blindness, but they didn’t understand the mechanism behind why until now.
