ScreenTime Blue Blocking Screen Filter/Protector
This ScreenTime blue blocking screen filter and protector reduces blue light from your phone by about 60%. It also protects your iPhone screen against scratches and damage. Blue light has been strongly linked to macular degenerative disease, cataracts, myopia as well as hormonal imbalances in the body. Expose your eyes during the day to natural light and shield it from blue light after sunset.
