to the second plastic layer in adhering relationship thereto where one of the opposing surfaces of the second transparent medium is smooth and becomes the outside surface of said optical layered structure formed by the first transparent medium the first and second plastic layer and the second transparent medium the invention also relates to the structure formed by such method application_number US 54057590 A description an example of sunglasses 2 having the novel lenses 4 of the present invention is seen in fig1 of the drawings each of the lenses 4 comprises a laminated sandwich consisting of a front or anterior lens plate 6 a rear or posterior lens plate 8 the latter of which takes its position on the inside of the total lens structure next to the eye of the wearer and a micro thin layer 10 disposed between the anterior and posterior lens plates 6 and 8 the bas relief object which is chosen to be imaged by reflected light is used as a casting surface for forming the topography of the interior face 12 of one of the lens plates the anterior plate 6 as seen in fig4 a 4c is shown as an example the surface irregularities and undulations which form the contour of the pattern object are transferred directly to the interior face 12 by the process of casting or molding the lens plate 6 which can be of glass or a plastic material to the topographically contoured surface of the interior face 12 of the anterior lens plate 6 is added by well known deposition methods the micro thin layer 10 of a light reflective material such as gold in place of a deposited reflective.
