As we use devices more, our exposure to high-energy visible blue light (HEV) increases. HEV blue light has been shown to contribute to digital eye strain which can cause dry and irritated eyes, sleep disruption and loss, blurred vision, and premature eye aging, especially in children. InvisibleShield has developed a new screen protector with Eyesafe technology that not only protects your phone from scratches and impacts, but also filters harmful blue light from your device screen. The Eyesafe technology in VisionGuard protects your eyes from blue light which can contribute to digital eye strain. By blocking harmful wavelengths of light before they leave your screen, VisionGuard is an easy choice for those who care about eye health. Glass+ VisionGuard is chemically strengthened at the molecular level to preserve that glass-like feel of your screen. Its proprietary Ion Matrix technology provides the ultimate defense against drops, dings, and scratches. Glass+ VisionGuard is designed to work flawlessly with the enhanced optics of your device's screen. Its 100% clarity rating means high-definition screen protection that's so clear, you won't even know it's there. Glass+ VisionGuard protects your eyes from harmful blue light while maintaining the superior colour performance of your device display. Instead of removing blue entirely and distorting your screens colour like some eye health solutions, VisionGuard has been expertly engineered to maintain the brilliant look of your screen.
