According to the journal Scientific Reports, blue light may speed up the process of macular degeneration, the leading cause of blindness in the United States. Blue light turns certain molecules in the eye into "cell killers" which damage the photoreceptor cells we need for vision. Pure 2 EyeGuard for Apple iPhone X / Xs filters out up to 43% of harmful blue light–protecting eyes from digital eye strain and safeguarding devices from drops. Artificial blue light with wavelengths between 400 and 450 nanometers have been shown to be most harmful. Pure 2 EyeGuard is designed specifically to filter up to 43% of these blue light wavelengths.
