Eye Comfort Crystal Anti-Fingerprint Screen Protectors add blue-light reduction filters to your screen that only slightly warm the color temperature. They reduce blue light from your screen by 38% over the most harmful portions of the visible light spectrum (380 to 500 nm), and also block most UV-A (63%) and UV-B (90%). The filter has a crystal anti-fingerprint finish and increased 5H hardness for additional functionality and protection. This perfect balance of blue-light blocking and clarity gives you reduced exposure with full definition and great color balance. It may help with eyestrain, eye damage, and sleep disorders linked to blue light, especially for the office work and night time use. The crystal anti-fingerprint coating reduces the appearance of fingerprints on the screen, while also maintaining a vibrant and vivid crystal finish. That translates to less smudges, less fingerprints, and much easier cleaning. The Protector uses silicone glue for a secure, residue free attachment, and it can be easily removed and reapplied if necessary. Besides the screen protector, the package also includes a high-quality micro-fiber cleaning cloth and a dust isolation sheet to help prepare your screen for installation. You can use the in-depth video tutorials on Green Onions Supply"s home page to walk you through installation and trouble-shooting. The Screen Protector is very slim, so it is fully compatible with the capacitive touch-screen, and many cases or accessories for your device.
