The invention relates to a polishing film (1) for a polishing head (2) for plastic spectacle lenses (3), for polishing zones on a front side (3.1) or rear side (3.2) of the spectacle lens (3), having a polishing surface (1.1) which can be positioned against the spectacle lens (3) and is bounded by a peripheral surface (1.2), wherein an edge (1.3) is provided between the polishing surface (1.1) and the peripheral surface (1.2), wherein the edge (1.3) either has a radius r of at least 0.5 mm to 10 mm or has a chamfer f with an extent f1 × f2, where the extent f1 or f2 is at least 0.5 mm to 10 mm, or the polishing film (1), when not in use, has a basic curvatuve G with a radius RG >= 75 mm and, in addition to this, a peripheral curvature G with a radius Rg <= 0.5 G, wherein the peripheral curvature g is limited to the peripheral zone (1.4), or the polishing film (1) is formed without any basic curvature G and has a peripheral curvature g with a radius Rg <= 35 mm, wherein the peripheral curvature g is limited to the peripheral zone (1.4). |
