Unlike other blue light blocking eyewear, SafetyBlue computer lenses block the recommended amount of blue light for daytime use. They block 40% to 42.41% of blue light from 280nm-510nm. Not all blue light is bad. The blue-turquoise light range (465 nm to 495 nm) is essential to our vision and the function of our pupillary reflex, and to human health. It also helps to regulate our circadian sleep/wake cycle. Enjoy your digital screen time without worrying about eye fatigue, blurred vision, and headaches. Keep working and playing on your devices longer without sore, dry eyes or headaches. The lenses are clear, not yellow and not prescription. They will not alter your vision and have almost no color difference providing clear and comfortable vision with a blue light blocking, protective lens. Recommended for anyone using computers, laptops, televisions, smartphones, tablets for extended periods of time.

Are these even any use??? Damn you Amazon instant purchase
Had about 5 of similar products saved to my wish list, I guess eye strain made me one click buy the wrong one. I'm sure another item had the same picture and actually blocked blue lightThe title misses 40% reduction when saved to wish list. And the whole description doesn't mention it's only 40% reduction. Just whole dangerous blue light is and how the glasses block it. It needs to be added to the description. Partially blocks blue light not blocks blue light.How did I buy 40% reduction glasses lol. Is there any point to even having these?I'll probably just keep them anyway and buy a proper pair that actually blocks blue light.

Looks nice but not great for extended use
Looks and feels good when you first wear them but after about an hour, I found that they pinch my head a bit around the ears and felt a bit heavy around the nose. I found they worked well at night but were not great for wearing in the day or in brighter light.
