Snow goggle device and composite lens

A snow goggle device, comprising:

• a composite lens including:
• a multi-layer sheet defined as an internal view region and an internal combining region that is in a ring shape and is arranged around the internal view region, the multi-layer sheet including:
• an anti-UV layer having an inner surface and an outer surface opposite to the inner surface, wherein a UV light blocked by the anti-UV layer has a maximum wavelength that is defined as a first wavelength and is greater than or equal to 380 nm;
• an anti-fog layer disposed on the inner surface of the anti-UV layer;
• and
• a photochromic layer disposed on the outer surface of the anti-UV layer, wherein the photochromic layer has an adjustable transmittance that is changed when a UV light travels through the photochromic layer, and the anti-UV layer is configured to reflect a UV light traveling through the photochromic layer back to the photochromic layer;
• a protective sheet arranged adjacent to and spaced apart from the photochromic layer, wherein a UV light blocked by the protective sheet has a maximum wavelength that is defined as a second wavelength and is less than or equal to 380 nm, and wherein the protective sheet is defined as an external view region and an external combining region that is in a ring shape and is arranged around the external view region;
• and
• a combining layer connecting the internal combining region of the multi-layer sheet and the external combining region of the protective sheet, thereby fixing the relative position of the multi-layer sheet and the protective sheet,
• wherein the internal view region of the multi-layer sheet, the external view region of the protective sheet, and the combining layer are substantially sealed to jointly define an air layer, and the air layer is configured to slow down the transference of an outer temperature of the protective sheet to the multi-layer sheet;
• and
• a spectacle frame fastened to a periphery portion of the composite lens, wherein the internal combining region of the multi-layer sheet, the external combining region of the protective sheet, and the combining layer are fixed on the spectacle frame.
