Abstract: A welding lens includes a variable light transmission shutter that automatically darkens in response to light emitted from a source. An intensity of the emitted light is sensed by a photo-sensor located on a front face of the welding lens. Internal circuits located within a housing of the welding lens receive data from the photo-sensor and correspondingly darkens or lightens the variable light transmission shutter based on the intensity of the light. The housing is 50.80 mm in width and 107.95 mm in length to fit in corresponding welding helmets and the housing is made from stainless steel to reflect infrared radiation that would otherwise overheat the internal circuits within the welding lens.
