PURPOSE:To narrow the disposition pitch of electric heat wires of the antifogging lens for, for example, goggles for skiers and goggles for riders formed to improve the visual field by removing the fogging by the water drops, etc., generated on the surface of the lens without hindering the visual field while reducing the electric power consumption of a portable battery and to eliminate the unequal temps. thereof. CONSTITUTION:An electric resistance wire 7 extended to the lens 4 is constituted of a steel wire consisting of a low-carbon two-phase structure having 5 to 50muOMEGAcm electric resistivity, <=100mum wire diameter and >=300kgf/mm<2> tensile strength when the lens 4 is so formed as to remove the fogging thereof by impressing 3 to 12V low voltage to the above-mentioned electric resistance wire 7. |
