METHOD FOR THE DETERMINATION OF A PROGRESSIVE OPHTHALMIC LENS |
摘要 |
A method for the determination by optical optimization of a personalized progressive ophthalmic lens intended to be inserted into a frame chosen by a given wearer for whom a power addition has been prescribed in near vision, the method comprising the stages of: - determining at least one parameter representing the frame chosen by the wearer; - measuring parameters representing the wearer's head-eye behaviour; - weighting the parameters representing the wearer's head-eye behaviour with the parameter representing the frame chosen by the wearer; - determining power and resulting astigmatism defect targets for each direction of viewing under wearing conditions, the targets being associated with an individual merit function taking into account the weighted head-eye coordination parameters. The method allows the design of the lens to be adapted to the size and the shape of the frame chosen.
