Patent number: 8272736Abstract: A method for treating an ophthalmic lens comprising two main sides, wherein at least one side comprises an organic or mineral external layer coated with a MgF2 temporary protective layer, said method comprising the specific treating step of depositing the MgF2 temporary protective layer on the external layer through vacuum evaporation at a speed lower than or equal to 0.5 nm/s. The lens obtained from the above method is capable of being submitted to a trimming operation within 48 hours after the ophthalmic lens has been treated, i.e. after the various layers have been deposited.Type: GrantFiled: December 22, 2008Date of Patent: September 25, 2012Assignee: Essilor International Compagnie Generale d'OptiqueInventors: Pascale Lacan, Dominique Conte

Patent number: 8260450Abstract: An eyeglass lens processing apparatus for forming a hole on an eyeglass lens to attach a rimless frame to the lens, includes: a lens chuck that holds the lens; a drilling tool; a designating unit that designates a position of a hole; a unit that measures or inputs an inclined angle of a refractive surface of the lens at the designated hole position; an arithmetic unit that obtains a hole angle with respect to a predetermined reference axis based on the inclined angle; a control unit that controls a positional relationship between the held lens and the drilling tool based on the obtained hole angle to perform a drilling; and an input unit that inputs a modified hole angle based on the obtained hole angle. The control unit controls the positional relationship between the held lens and the drilling tool based on the modified hole angle to perform a re-drilling.Type: GrantFiled: February 28, 2007Date of Patent: September 4, 2012Assignee: Nidek Co., Ltd.Inventor: Kyoji Takeichi
