The Eye Comfort protectors add blue-light reduction filters to the screen that only slightly warm the color temperature of your screen. They reduce blue light from your screen by 38% over the most harmful portions of the visible light spectrum (380 to 500 nm), also block most UV-A (63%) and UV-B (90%) from the screen, which come with 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 or 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 new anti-fingerprint oleo phobic coating resists the attachment and appearance of oil on the screen. That translates to less smudges, less fingerprints, and much easier cleaning. Besides the screen protector, we have also included a high-quality micro-fiber cleaning cloth and a dust isolation sheet to help prepare your screen for installation. You can use our in-depth video tutorial 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.
