The Zagg InvisibleShield Glass+ VisionGuard Screen Protector protects your device's screen from scratches and impacts, and your eyes from harmful blue light that causes digital eyestrain. It is chemically strengthened at the molecular level to preserve that glass-like feel of your screen, and its proprietary Ion Matrix technology provides the ultimate defense against drops, dings, and scratches. This shield is equipped with EyeSafe technology that protects your eyes from blue light, which can contribute to digital eyestrain by blocking harmful wavelengths of light before they leave your screen. Additionally, this screen protector also maintains the superior color performance of your device display. Instead of removing blue entirely and distorting your screen's color, VisionGuard has been expertly engineered to maintain the brilliant look of your screen.
