A fog-resistant structure and a protective device for eyes is configured such that a transparent conductive film is formed on one surface of a lens or shield, a linear electrode is provided on upper and lower portions of the surface of the lens or shield so that each of a central region and opposite side regions of the lens or shield has substantially equal spacing between the upper and lower linear electrodes. Thus each region of the lens or shield has no difference in temperature without regulating power supplied to the transparent conductive film, thereby eliminating wasted power consumption and allowing even a structure using a battery as the power supply to have much longer available time.

Fog-resistant structure and protective device for eyes

The synthetic resin lens has a function to generate heat by selectively absorbing infrared rays with wavelengths of 780 to 3000 nm. The synthetic resin lens includes an infrared absorber. Selective absorption of infrared rays allows the synthetic resin lens itself to generate heat and thus the lens of the present invention has the same function as being electrically heated to prevent fogging.
