A polishing film for a polishing head for plastic spectacle lenses, for polishing zones on a front side or rear side of the spectacle lens, having a polishing surface which can be positioned against the spectacle lens and is bounded by a peripheral surface, wherein an edge is provided between the polishing surface and the peripheral surface, wherein the edge 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, when not in use, has a basic curvature 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, or the polishing film 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. |
