Buy one pair of blue light-blocking eyeglasses, get another pair free – CNET

We’ve been hearing for years now that the blue light streaming out of our computer screens isn’t great for us. Pop science suggests that it causes eyestrain and disrupts sleep cycles, which is why iPhones and Android phones now have night modes that filter out blue light — although more recently, research may be suggesting night modes hurt sleep, as well. If you like the idea of blocking blue light, another approach is to get eyeglasses that automatically filter out the blue for you. Glasses USA has rolled out a line of frames with blue light-blocking lenses and is offering a buy-one-get-one-free deal on Bluease frames if you check out with discount code BOGOFREE. That’s worth up to about $100, depending upon the frames you select.

Glasses USA has about three dozen styles of frames with blue-blocking lenses, and you can purchase them with nonprescription lenses that block 95% of the target blue light, or you can upgrade them to prescription lenses with the same blue-blocking tech. The lenses are also scratch-resistant, have an antiglare treatment and block UV light as well.

It’s worth asking the question: Do blue light-blocking lenses actually do what they claim? The answer is that it’s hard to know for sure and the jury is still out. CNET’s Sarah Mitroff tried to get to the bottom of whether blue light-blocking glasses actually work, and she found that there’s conflicting evidence about how blue light exposure affects your eyes. One thing we can say is that science appears to show that blue light does affect your circadian rhythm, which can affect sleep, but there’s scant evidence to show that computer and phone screens contribute meaningfully to this problem. 

While we wait for additional research, if you want to give blue-blocking glasses a spin, getting a free pair of frames is a cost-effective way to try out blue light-blocking glasses, which brings us back to Glasses USA.
