Many people believe that blue light could be damaging our eyesight and health. But what does science say? We asked the experts.
suggested that when people are exposed to blue light in the evening hours, their bodies don’t release as much melatonin, which could delay and disrupt sleep cycles.
However, Dr Perry suggests that, despite the lack of evidence, blue light could be inadvertently impacting our eyesight: “It is well known that sitting in front of the PC leads to 50% less blinking per minute ,” he says. “This can lead to dry and red eyes, which in turn can put more strain on the eyes.”One solution to the potential effects of blue light is blue light glasses, which are designed to filter out blue light.
However, this was a very small study and Kanabar stresses: “There is no clear evidence to support that these kinds of coatings prevent eye disease such as age-related macular degeneration.”bedtime Given that, it’s probably best not to fork out a lot for something that is potentially under-studied. But if blue light glasses have a positive impact on you, there’s seemingly no harm in wearing them.
