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 have to mess with any apps or settings—it does its thing as you scroll. The ultrathin design keeps your screen clear and responsive to touch, and it includes a two-way privacy filter. 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.
