No matter, the brand name, or size of the frame the sole purpose behind fancy blue-light blocker glasses is to block harmful blue light emitted from your devices.

Blue Light Blocker Glasses

"Now in modern times we get blue light exposure from light bulbs in our house, from devices like cell phones, computers, know we are constantly surrounded by it...and now we get it around the clock instead of just during daylight hours," Dr. Ryan Burton, an Ophthalmologist at Premier Medical Group, explained.

People commonly know of the blue light that is emitted from our electronic devices, but we are exposed to it in other ways as well. Whether you’re a heavy computer user, UV+ Blue Blockers can be worn like regular glasses to protect your eyes from harmful blue light emitted from any digital device, as well as artificial fluorescent and LED light exposure. 

"Certainly looking at tablets and phones can certainly cause some strain but a lot of that is that's more due to the up close vision and dryness that comes when we are starring at something for a long time," said Dr. Burton. 

Prolonged exposure to blue light can have damaging effects on your eyes over time.

One of the biggest concerns with blue light, is macular degeneration. The more exposure to blue light, your macular, which allows your eye to see detail, deteriorates.

Since the glasses only block around 30 percent of the blue light, there are some other things you can do to lower your exposure to the light.

"So there is some evidence that it's effective in trying to limit impact on the sleep wake cycle and the melatonin levels that we see related to blue light but in terms of overall eye health...there's not really a lot of great evidence that shows they will make a difference in that part," Dr. Burton expressed.

His advise for heavy screen users: first try to be as far away from your screen as you can…and try not to be staring at your screen for more than 15 to 20 minutes at a time and then take a break.
