摘要

Method for the determination of an ophthalmic lens using a prescription of astigmatism for the vision of far and near vision, and the lens is obtained.The invention relates to a method for the determination through the optimization of an ophthalmic lens, taking into account not only the requirement of the user to the vision of far away: the intensity.The amplitude and axis of astigmatism, but also the requirement of user for near vision. The prescription of near vision is measured with binocular vision.The lens is thus defined by the optimization using the prescription for the intensity and the astigmatism to the vision of far and near vision as a target.According to the invention,The changes in astigmatism from the conditions of vision can be explained for the objects that are generally further away to the far vision than for near vision.May also be taken into consideration variations in astigmatism caused by deformation of the eye in its physiological rotation along a direction to a direction of view primary visionAdapted to near vision.
