Abstract: This invention relates to a manufacturing method for production of visibly heterogeneous or asymmetrical sunglasses, eyeglasses or frames. The production method mass produces a product comprising a randomly selected motley assembly of asymmetrical lens frames, for example, wherein a component of the left frame is different from a component in either the left frame or the right frame and/or where the product is sunglasses, the left lens is of a different color from the right lens, for example. Further, in the method both differing aspects may occur in the manufactured product. The sunglasses made by a random selection of right and left framed lenses of different colors, for example, and/or by a random selection of right and left differently framed lenses or by a random selection of both. In the method for manufacturing parts of the frames are randomly selected from sets of randomly pre-assembled sub-assemblies.
