  • Publication number: 20220273064
    Abstract: Proposed is a transparent heating element for an eye protector such as goggles for snowmobiling, skiing, motorcycling, and the like on which a lens is mounted, and is a manufacturing method thereof. On a surface of a transparent base that configures the lens of the eye protector, a lattice film formed of a dried material or a calcined material of a conductive ink or a conductive paste is provided. The lattice film has a line width of 2.5 ?m to 20 ?m, a lattice pitch of 0.1 mm to 5.0 mm, a surface resistance value of 10 ?/cm2 to 50 ?/cm2, and a light transmittance of 90% when the transparent base is excluded. An anti-fog coating treatment is performed on the opposite surface of the transparent base. The surface resistance value is partially changed by changing the lattice pitch.
