I'm not going to address all the great things about them as they are summed up very well by other reviewers but I will talk about all the one star reviews saying they do not block blue light. The color of light is dependent upon the wavelength of the electromagnetic wave in which that light photon travels at. Blue light has the shortest wavelength of light that is emitted from electronic screens (screens emit red, blue, and green light) and therefore has the most energy per photon. This type of light is most harmful to our health as it contains more energy than the other colors. Light is emitted as a spectrum, each individual color corresponding to a certain wavelength of light.\n\nThese glasses DO block certain wavelengths of blue light, it can be clearly seen by the blue light and test card given with these glasses. However, they only block a certain percent of blue light throughout a specific range of the blue light spectrum. For anyone expecting 100% of blue light to be blocked by a clear lens is flat out idiotic. If this was true, what would you expect to see when looking at something blue? Grey? Black? Nothing? These glasses block certain wavelengths of blue light that I would GUESS would be the most harmful of the wavelengths to our health, and the effects of blocking this light are truly noticeable. You can see blues just the same with prescription glasses with the blue light filter, are those false and a lie as well? Highly doubtful.\n\nIf you want to block ALL/MOST blue light, you must get glasses with a dark amber/yellow tint to them. This blocks a much broader range of blue light frequencies but do not look very good and shift the perceived color of everything else as well, two traits that are not very desirable. With these glasses, some of the most damaging light blue light is blocked, colors still look clear and accurate, and they look really good! A win-win! Please when purchasing a product or writing/reading reviews use some common sense as to what you are actually getting. Not only do they block blue light but I tested the blue light and the card provided with the product with my mom's prescription glasses with the blue light filter and they failed!"}, {'review_meta': 'Reviewed in the United States on September 17, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'Amazing & cute! Look at the blue ray blockage from these glasses! Top glasses are my own, bottom are the ones I ordered. Insane blockage! Super cute color too 😁'}, {'review_meta': 'Reviewed in the United States on September 2, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "These glasses are well built, stylish and don't turn the world yellow. What more can you ask for from some UV protection glasses. I am a photographer and found myself using them for photoshoots because they look expensive, but I never have to worry about damaging them because for 6 bucks each, you can always replace them!"}, {'review_meta': 'Reviewed in the United States on September 9, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'All that I wanna say is thank you for seller.\nQuality for this price is amazing.

They’re super affordable, stylish, and they’ll protect your eyes from the many hours a day we all spend on our electronic devices. Would definitely recommend.

One for each outfit lol'}, {'review_meta': 'Reviewed in the United States on September 2, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': 'I live this glasses fits perfectly and are beautiful!

The pattern is super cute and girly while the black frames are a bit more masculine. Great for looking at the computer all day and sensitive eyes. I love that they are trendy and effectively helpful!'}, {'review_meta': 'Reviewed in the United States on December 20, 2019', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': 'These glasses do not block blue light, they are just clear lenses. In my photo you can see these glasses on the top and my previous blue light blocking glasses on the bottom. As you can see the bottom ones reflect the blue light waves and the top ones do not. They did not help with eye strain when worn, so I will be returning.'}, {'review_meta': 'Reviewed in the United States on October 17, 2019', 'review_star': 'a-icon a-icon-star a-star-1 review-rating', 'review_body': "I was skeptical based on the reviews, but for the price (and Amazon's easy return policy), I figured why not try them? Well, let me save you the trouble if you're having the same thought. These may be UV blocking or anti-glare, I didn't bother testing further once I found they block absolutely no visible part the light spectrum.\n\nOptically clear, reasonably comfortable, but if like me you are purchasing them actually block the high-frequency part of the visual spectrum, steer clear! These do not do it!\n\nIn the picture, the diagram on the left should be similar to the diagram on the right, where blue spectrum light was digitally removed. It is not being done optically though, so the blue light remains visible through the lens in the left diagram."}]
