Abstract
A fresnel magnifying lens for forming a hand-held, pocket-sized hybrid assembly of the lens and another object or objects. The lens is provided with at least one hole for use with a fastener to detachably or permanently couple the lens to the other object in a manner which allows a selective magnified hand-held viewing, through the lens, of both the other object, as well as different objects. The coupling of the lens to the other object is such that the lens can be slidably moved, using the fastener which couples the lens to the other object as a pivot point, to permit the lens to be used to view different objects which are not part of that hybrid assembly. The pocket-sized fresnel magnifying lens can thereby be attached onto a variety of objects, for example, marketing objects, such as credit cards, debit cards, ID cards, pocket calenders, schedules, telecards, magnetic note holders, key rings, etc., thereby permitting improved accessibility of the visual aid provided for by the fresnel lens to individuals and consumers. This piggy backing scheme of the lens onto such marketing objects allows the marketing objects to be even more powerful marketing tools in view of the inherent ac…
