Abstract
Disclosed is a method for packaging an optical lens including two faces and a peripheral edge, at least one of the faces having a convexity marked by a peak point, the method including the following steps: a step of depositing a protective strip made from a rigid material at least partially along the edge, the width of the strip extending beyond the peak point of the convex face of the lens; a step of inserting the lens into an envelope delimited by a wall; a step of positioning the lens in the envelope, such that the protective strip acts as a spacer in order to maintain a distance between the wall of the envelope and the convex face of the lens and thus preventing any contact between the wall and the face.
