204;
304) being configured to be attached to said ophthalmic lens (2), and an attachment member (5;
105;
205;
305) configured to be positioned on said positioning and centering pin (4;
104;
204;
304) and to be attached to the latter and also to be attached to said ophthalmic lens (2), characterized in that said system also has a tool (20;
120;
220;
320) for positioning said attachment member (5;
105;
205;
305) on said positioning and centering pin (4;
104;
204;
304), said tool (20;
120;
220;
320) having a body (42;
142;
242;
342) provided with at least one receiving recess configured to at least partially receive at least one of said attachment member (5;
105;
205;
305) and said positioning and centering pin (4;
104;
204;
304), at least one centering member (48, 56;
148, 156;
257) for centering said attachment member (5;
105;
205;
305), and at least one guiding member (48, 57;
148, 157;
256) for guiding said positioning and centering pin (4;
104;
204;
304);
said recess, said at least one centering member (48, 56;
148, 156;
257) and said at least one guiding member (48, 57;
148, 157;
256) being configured such that, when said attachment member (5;
105;
205;
305) and said positioning and centering pin (4;
104;
204;
304) are mounted on said tool (20;
120;
220;
320), said attachment member (5;
105;
205;
305) is centered with respect to said body (42;
142;
242;
342) and said positioning and centering pin (4;
104;
