Title:
GLASSES WITH ELECTROMAGNETIC WAVE PREVENTING FUNCTION AND ITS PROCESSING METHOD
Document Type and Number:
Japanese Patent JP3914699
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide glasses which can protect eye-balls of a VDT(visual display terminal) user from a magnetic field generated from the VDT, to provide glasses in which lenses are electrically grounded from an electric field generated from the VDT and to provide a processing method thereof.
SOLUTION: The glasses which can protect the eye-balls of the VDT user from the magnetic field generated from the VDT by providing a magnetic field shielding plate 3 formed of a magnetic body above a frame 2 and at both flanks thereof, can be provided. Further the glasses provided with grounding action can be provided by forming an electrically successive path running from an electromagnetic wave shielding coating of the lens 1 to skin of a glasses user via the frame 2 by a processing method by which an electrically conductive material is applied on a flank of the lens 1.
