Abstract: An anti-glare eye protection apparatus includes an anti-glare eye protection plate, an optical detector, an electromagnetic wave sensor, an electromagnetic wave detector, a user interface, a main controller, and a light transmittance controller. The electromagnetic wave sensor senses an electromagnetic wave generated by a welding or cutting torch using at least two coils. The electromagnetic wave detector compares a signal received through the electromagnetic wave sensor with a reference value. The user interface includes a display for selecting or displaying one of the optical and electromagnetic wave detectors. The main controller applies an electromagnetic wave detector activation signal to the electromagnetic wave detector as the optical detector starts optical detection and monitors changes in a received electromagnetic wave signal based on output of the electromagnetic wave detector.
