Abstract: A low inventory method of making eyeglasses. Two lens elements having special complementary surfaces are provided. These lens elements can be positioned relative to each other to provide wide ranges of focus correction and astigmatism correction. Various preferred embodiments of the invention are described. In one embodiment the required inventory is only identical sets of two complementary lenses for providing correction for almost all needed eye correction for a typical population. In this embodiment, the lens units are first adjusted relative to each other to provide a desired focusing power. Astigmatism may be corrected by a small adjustment in a second direction perpendicular to the first direction followed by a rotation of the two lenses about the axis of the two lenses. When the adjustments have been made the two lenses are fixed with respect to each other and installed in eyeglass frames. Cutting to the shape of the eyeglass frames can occur either before or after the fixing.
