Abstract: A method for manufacturing eyeglasses. In the method a preform for the eyeglasses is injection moulded of transparent plastic, the preform comprising lens areas and a frame connecting them and arranged seamlessly thereto, and a computer-controlled printing is performed on the preform for providing one or more functional and/or decorative coatings, the printing being directed at least to the lens areas. The computer-controlled printing in also directed to the frame. Thus, the outline of a frame area is printed. In a second embodiment of the invention, there is injection moulded an eyeglass frame that forms a continuous, endless and elastic component around the lens holes. The lens holes are compressible around the lenses fitted in the lens holes. Computer-controlled printing is directed to the frame for providing one or more functional and/or decorative coatings.
