Review on 👓 CHEERS DEVICES 5 Pack Reading Glasses: Blue Light Blocking Eyeglasses for Men & Women, Effective Computer Readers with Anti Glare Technology by Fernando Ramani

Just bought and tested. Verdict: Do not buy: These are very typical standard quality UV reading glasses. They are absolutely useless for blocking blue light or UV rays from computers or phones. They block UV from sunlight, but sunglasses would be a much better choice for this. Recommendation: do not buy. If you need reading correction, buy good reading glasses. If you work outdoors where UV radiation is a problem, get sunglasses with UV protection. If you're sensitive to blue light from phones or monitors, use the blue correction feature built into your Apple, Android or Windows device, or visit justgetflux.com for a demo from your Windows PC. To prevent fatigue, 1) adjust monitor and room lighting, 2) adjust text size and resolution to be comfortable, and 3) take regular breaks while moving and looking at different distances. Let's clarify what these glasses do. You need a reading distance correction. But these are cheap glasses, and they don't handle reading fatigue as well as the ones your optometrist prescribed. The anti-reflective coating is just the glare from the glasses themselves, so if you don't wear glasses you won't be blinded. And since most goggles have that, it's not exactly an advantage. Remove "harmful blue light" and UV400. This is very deceptive. These glasses do nothing for computer and phone monitors. Let's explain. These goggles block UV but not as much blue and definitely don't help with computer monitors. Your demonstration is a trick. The demo uses the fluorescent card trick. They compare what a test card looks like before and after exposure to UV light through glasses. Because the glasses block UV light, they prevent UV light from reaching the card and fluorescing. BUT if you wear glasses you will find that the map still looks bright in the light. This is because the UV of the light hits the card, converting the UV to visible light and then allowing the blue-white light to pass through the glasses and into your eyes. UV radiation is radiation with a wavelength of 400 nm and above. Visible light is around 400nm to 700nm. Blue light is between 400nm and 450nm. These glasses block 400nm and up, so they block UV. However, they do not significantly block blue light or other light in the 400-700 nm range. That is why the glasses look transparent. In addition, computer and phone displays do not emit UV or blue light around 400nm. Their blue color is very different. Therefore, these glasses do not significantly alter the light from computers or phones. Bottom Line: These are UV goggles that don't block visible light to any great extent. These glasses do not block light from computer monitors. The manufacturer uses a fluorescent trick to make the glasses appear to block visible blue light, which is not true. A few words about the blue light. There are two issues: UV damage and circadian rhythm. Computer and phone displays do not emit UV or "harmful blue light" so this is not a problem. UV radiation is mainly associated with sunlight. Computers and phones can display whites like lightbulbs—soft whites or bright whites in daylight. Some people think that the white color of daylight, which is the standard color for computers and phones, disrupts their circadian rhythms, leading to trouble sleeping. Apple, Android, and Windows include features that warm up the color of your display and make it look more like a soft white when you find it useful. People generally do not use fluorescent lights in their homes as they find them uncomfortable. In the evening, Softwhite is more commonly used at home for the same reason.
