    I’ve been extremely pleased with my experience with this purchase. The frames are very trendy and durable and the lenses do a fantastic job blocking the blue light. They are also so lightweight sometimes I forget to take them off after work. I recommend this product!

    As one who strives to maintain the healthiest of lifestyles between eating organic, keto/carnivore, taking appropriate whole food and mineral supplements, coupled with a consistent workout regimen, nothing has been able to prevent my eyes from fatiguing by mid-day, until now. It's obvious technology shouldn't belong in the mix, however, in this day and age it's inevitable to avoid. Photo and video editing is a bare necessity these days if you're attempting any sort of career, or promoting a business or products. That along with social media, TV, video games, mobile games, and the myriad of streaming services out there keeps the world glued to screens, these blue artificial light blockers exceed expectations. I spend a minimum of 6 hours a day looking at screens, and now having tried them a solid week I feel I can voice an opinion and say with confidence that my eyes feel nearly as good in late night editing sessions as they do when I wake up. It took about 3 days of use to recuperate from so much fatigue, but after experiencing the effects, I'd never go back. However, to say color accuracy is important for editing or graphic arts is an understatement, so I can't ignore mentioning the one unfortunate, but necessary con that all blue-light glasses contain, including these: the noticeable yellow tint to the lenses. That being said, I've tried a couple of pairs in the past, and these by far have the weakest, least intrusive tint of them all, so one certainly can't hold it against them by showing it in the ratings. No more fatigue, no more bloodshot eyes. Proven effective. Fantastic Job, Umizato.

    The glasses are extremely comfortable and feel very lightweight, yet durable. I love the design and they fit well on my slim face. I like how the lenses do not appear yellow like other blue light blocking glasses. They work very well so far.

    Excellent, comfortable and stylish.

    I have been wearing blue blocker glasses all day, every day, for over a year. I am a software developer and with me staring at a screen all day I get terrible headaches without them. This is my first pair of Umizato glasses, and I absolutely love them. They are excellent quality, lightweight and well made. After trying numerous different brands and then wearing this pair I wonder why it took me so long to find Umizato. Thank you to everyone at Umizato!
