Snow goggles device and manufacturing method thereof having a passively defrosting thin film

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; forming at least one transparent conductive film on the first surface, the second surface or therebetween; electrically connecting the at least one transparent conductive film with a power supply unit and a switch unit, with providing the power supply unit and the switch unit on the snow goggles frame; and operating the power supply unit to supply a current to the at least one transparent conductive film via the switch unit to thereby heat the optical substrate layer.
