METHOD AND DEVICE FOR DETERMINING AT LEAST ONE CUSTOMIZED ADJUSTMENT PARAMETER OF A LENS CARRIED BY A SPECTACLES FRAME FACING THE EYE OF A WEARER

摘要

The invention relates to a method for determining at least one customized adjustment parameter of a lens carried by a spectacles frame facing the eye of a wearer. According to the invention, the method involves determining a first pantoscopic angle (THETA1) formed between the holding plane of a lens and the vertical when the wearer adopts a seeing posture, said method comprising the following steps (a) determining a postural parameter of the wearer of the spectacles frame in a seeing posture, (b) determining a second pantoscopic angle (THETA2) formed between, on the one hand, the projection of the side of said frame in the sagittal plane of the wearer and, on the other hand, the line, in this same plane, of the front face of said frame, and (c) determining said first pantoscopic angle (THETA1) as a function, firstly, of the second pantoscopic angle (THETA2) determined in step (b) and, secondly, the postural parameter of the wearer determined in step (a).
