Abstract
A manufacturing method of a snow goggles device includes: providing an optical substrate layer on a snow goggles frame; providing the optical substrate layer with a first surface and a second surface, and providing at least one transparent photo-thermal conversion film on the first surface, the second surface or therebetween; the transparent photo-thermal conversion film absorbing a light ray or a light beam to convert into heat energy; and utilizing the heat energy generated the transparent photo-thermal conversion film to heat the optical substrate layer.
Claims14
A snow goggles device comprising:
- an optical substrate layer provided with a first surface and a second surface;
- a snow goggles frame provided with a predetermined area, with providing the optical substrate layer on the predetermined area of the snow goggles frame;
- and
- at least one transparent photo-thermal conversion film provided on the first surface, the second surface or therebetween;
- wherein the transparent photo-thermal conversion film can absorb a light ray or a light beam to convert into heat energy which can be utilized to heat the optical substrate layer for preventing the optical substrate layer turning into a frozen state.
