US Patent 10357672 Apparatus, system and method to prevent fogging of eyewear

An apparatus, system and method to prevent fogging of glasses worn by a wearer has a mask made from a filtration material. The mask has a left side and a right side. A strap extends from the mask to hold the mask in position on the wearer. A vent is positioned on both the left side and the right side of the mask, in one version. An adhesive foam layer extends across the mask and the strap to attach the mask to the glasses. Arms may extend from the glasses toward ears of the wearer. The adhesive foam layer attaches the mask to the arms of the glasses. A flap extends from the foam layer. Pulling the flap removes the adhesive foam layer from the glasses.
