Abstract
An optical magnifier has two light transmissive substrates with lenses on either side of each substrate and wherein the arrays of lenses are aligned such that an array of afocal optical magnifiers is produced. One of the arrays forming the array of afocal magnifiers has positive lenses and one of the arrays forming the array of afocal magnifiers has negative lenses. Two arrays of afocal magnifiers are combined to form a pair of magnifying glasses.
