This tempered-glass screen protector does more than just protect your phone from scratches. It transforms the blue light from your screen into red light. Why? Blue light can have a negative impact on your eyes, your skin, and your sleep; on the contrary, red light can be beneficial. The light-converting technology is built right into the glass, so you don’t need to adjust any apps or settings—it works automatically as you scroll. The ultrathin design keeps your screen clear and responsive to touch. Installation is easy, too: You apply it just as you would a regular screen protector, and the included alignment tray makes it quick and seamless.
