Abstract
The invention relates to a method for adjusting the position of a transparent element (1), consisting in forming an image of a peripheral edge (B1) of the transparent element, using the light diffused by said peripheral edge. In this way, movements by the transparent element relative to reference marks can be followed on a screen or carried out automatically based on an analysis of the image. The method can be used to apply a piece of film (2) to a spectacle lens, adjusting the distance between the respective peripheral edges (B1, B2) of the spectacle lens and the piece of film.
