Stretch the DefenderShield Sleep Mask over your head so it completely and comfortably covers your eyes. Make sure to adjust the hook-and-loop closure in the back of the eye mask to have a secure, but comfortable fit. Wireless EMF shielding is sewn behind the mesh on the eye-piece and the sides located by the temples.
Use the DefenderShield EMF Mask while sleeping, resting, or meditating to get complete light reduction, as well as wireless EMF protection for nearby EMF-emitting sources. Your eyelids can block light frequencies, but they do not prevent radio frequency radiation from penetrating the retina, which is the closest neural pathway to the brain.
