Abstract: The present disclosure relates to an electrochromic lens for use in an eyewear apparatus. More particularly the present disclosure includes a lens incorporating a high coloration speed electrochromic element within the lens. The high coloration speed electrochromic element includes an insulating layer, comprising an electrically insulating material with a dielectric constant of at least 10, positioned between two electrochromic materials having one or more optical properties that may be changed upon application of an electric potential with switching speeds that are less than 5 seconds. An opposite electric potential may be provided to reverse the change in the one or more optical properties. Methods of preparation of the lenses and the associated eyewear assemblies are also described herein.

Abstract: A face mask includes an outer layer, an inner layer, and a filter. The outer layer includes an outer front guard constructed from a light-transmissive material and an outer filtering surface extending posteriorly from the outer front guard that includes at least one outer air hole. The inner layer is nestled within the outer layer. The inner layer includes an inner front guard constructed from a light-transmissive material and separated from the outer front guard by a buffer space. The inner layer also includes an inner filtering surface extending posteriorly from the inner front guard that includes at least one inner air hole. A filter is positioned between the outer filtering surface and the inner filtering surface and covers the at least one outer air hole and the at least one inner air hole.

Abstract: There is provided a welding helmet (1) that has a protective shield (2) and a head suspension system (6). The protective shield and the head suspension system are pivotally connected to each other for swiveling the protective shield relative to the head suspension system about a pivot axis in opposite directions upward or downward between a protective position, in which the protective shield covers a wearer's face, and an upraised position, in which the protective shield uncovers the wearer's face. The welding helmet further has a stop mechanism that restricts downward swiveling beyond the protective position. The stop mechanism (10) is adjustable by a worm gear mechanism (11, 12) between a low position and a high position. In the low position the protective position of the protective shield is offset downward with respect to the high position.
