I bought this as an alternative to purchasing an anti blue screen for my computer. My Windows 10 computer had something called 34;Eye Care Switcher34; that has disappeared with a Windows 10 update. I bought the computer just for that reason. I started having eyestrain, headaches, migraines from the blue light. The opposite color of blue is yellow so I thought of blue blocker sunglasses and decided to buy the cello wrap in blue, cut out 3 squares and tape them onto my computer screen. Its a lot cheaper than buying a 75. screen cover. And it works.
