Review: This protector is amazing and it truly blocks blue light! - I tested the protector with a blue light beam and it works great – it truly reduces blue light but at the same time preserves the colors and the quality of the picture. I often work late at night and I have noticed that after installing the protector my eyes feel better and I fall to sleep more easily. So it truly preserves the circadian rhythms.My item arrived fast and it was securely packaged. The design of the item is great – it is very stylish and easy to install. Also, the protector prevents my screen from dust and scratching. Strongly recommend to everyone!
Review: Screen protector is great - I was amazed at how better the picture was on my eyes. I'm developing cataracts and brightness wasn't good at all. I lowered it through the TV by 50% and with this shield to eliminate more blue ray, my eyes don't water as much and there's less strain when binge watching. It's a great piece. Attaching it to the TV was a bit awkward, but I managed to secure it well. With grandkids 3 and 5 I didn't want it to be able to come loose with them around and managed that after some doing.
