1. A method of manufacturing spectacles of the type which does not have a lens-holding frame and which has a single, wrap-around front lens structure that can extend laterally beyond the main visual regions, and which also has respective arms for the lateral support of the spectacles, predominant portions of the respective lateral arms of the spectacles are produced integrally with the front lens structure by a process for the forming of plastics material with which a semi-finished lens is produced, so that the spectacles are consequently produced in a single piece, wherein by the forming step the spectacles comprise a single front lens structure having a marked degree of wrap-around and in which the main visual regions with the optical properties are incorporated and in that, after the forming step, a step is provided for shaping the semi-finished lens by machining with the removal of material, during which the arms and the single front lens structure are shaped to the final shape in accordance with a preselected style.
