Eyeglass loupes are a set of adjustable, swinging lenses that can be mounted to a pair of goggles or eyeglasses, or on a monoggle; magnifying the wearer's vision to help them observe minute details of small objects. When worn, they provide a +2 circumstance bonus to Appraise and Craft skill checks involving items that are small or highly detailed, and on sight-based Perception skill checks when inspecting something within 5 feet. These bonuses decrease to +1 if mounted on a monoggle. However, the arms become misaligned if the wearer falls prone or is grappled, or if the loupes or eyewear they're attached to become damaged. If the arms are misaligned, they lose their usefulness until readjusted (a full-round action that provokes attacks of opportunity).
