Abstract: A lens apparatus for correcting vision or for magnifying, of a base lens, with first predetermined optical properties; and of at least one adhesive optical decal lens, each with its own predetermined optical properties; where the at least one adhesive optical decal lens may be attached to the base lens forming the lens apparatus; where the lens apparatus may have a third predetermined optical properties. The third predetermined optical properties may provide vision correction according to a prescription. The at least one adhesive optical decal lens and/or the base lens may be manufactured by embossing, and/or die cutting (stamping), yielding effective optical corrective and/or magnifying lenses quickly, easily, and cost effectively as compared against the labor intensive, time consuming, and expensive injection molding, grinding, and polishing processes presently used. Additionally, such adhesive optical decal lenses and methods may be used to extend the useful life of preexisting eyewear.
