Abstract: A protective eyewear with dual-mode sidearms allows the eyewear to be worn in the presence or absence of earmuff-type hearing-protection apparatus. The protective eyewear comprises: an eyeshield; a first sidearm that is pivotally connected to the eyeshield by a first primary pivotal connection that is located proximate a first major end of the eyeshield; and a second sidearm that is pivotally connected to the eyeshield by a second primary pivotal connection that is located proximate a second, opposing major end of the eyeshield, wherein at least a rearward portion of a second, rear part of each sidearm comprises a laterally-outward-and-downward-facing major surface that is a concave surface, wherein the primary pivotal connection of each sidearm is configured so that each sidearm can be pivotally moved between at least a first, lowered configuration and a second, raised configuration, and wherein the sidearms are configured so that when the protective eyewear is worn in combination with an earmuff-type hearing-protection apparatus and when both sidearms are in the second, raised configuration, the rearward portion of the rear part of each sidearm rests atop a junction between an uppermost portion of a compliant seal of an earmuff of the hearing-protection apparatus, and a side of a user's head.
