METHOD FOR PREPARING AN OPHTHALMIC LENS FOR THE FLUSH-FITTING OF A SURROUND OF A SPECTACLE FRAME |
摘要 |
The invention relates to a method for preparing an ophthalmic lens for the purpose of mounting it in a surround (110) of a spectacle frame having an inner face (114) provided with a fitment rib or groove (111) and bordered by a rear edge (116) turned towards the wearer and an opposite front edge (115), the method comprising a first step of acquiring the geometry of an acquired longitudinal profile (P1) running along the said inner face, and a step of milling the ophthalmic lens with formation on its rim of a fitment rib or groove extending along a deduced longitudinal profile whose geometry is calculated according to the geometry of the said acquired longitudinal profile. According to the invention, the method comprises a second step of acquiring a geometric characteristic (H1) which is relative to the position of the fitment rib or groove relative to the said front and/or rear edge of the frame, the geometry of the deduced longitudinal profile then also being calculated according to the said geometric characteristic. |
