An optical element, notably an optical element for creating a retractable sheet for use in a motor vehicle, has in the final state a three-dimensional shape resulting from forming of the optical element, the optical element being designed to have an extended shape comprising: a first main surface, a second main surface, and an edge surface. A method of manufacturing involves during a first step of the method, forming the optical element to give its final three-dimensional shape in terms of the first main surface, the second main surface and the edge surface. During a second step at least one of the surfaces of the optical element is cleaned. During a third step, a functional coating is applied to the first main surface and/or the second main surface.
