Abstract: Disclosed is a method for determining an updated visual correction need for designing a new vision correcting device of an individual already having a previous vision correcting device previously designed to correct his/her vision, wherein, in a first step, a previous level of correction of the previous vision correcting device is acquired, in a second step, a current vision acuity parameter of the individual wearing the previous vision correcting device is assessed, and, in a third step, the updated visual correction need is determined based on the previous level of correction of the previous vision correcting device acquired in the first step and on the current vision acuity parameter assessed in the second step. A complementary visual correction need can also be determined.

Abstract: A method for checking the compliance of a checked optical characteristic of a checked ophthalmic lens (30) relative to an expected optical characteristic, from a non-deformed pattern (40) and a deformed pattern (20) each having a non-uniform contrast, the method includes the steps of: a) determining (A) an image pattern (50), which is the image of the deformed pattern through the checked ophthalmic lens, in predefined optical conditions, b) combining (B) the image pattern with the non-deformed pattern to form a test pattern (60), c) comparing (C) the test pattern with at least one reference pattern (70), and d) deducing (D) the compliance of the checked optical characteristic with the expected optical characteristic on the basis of the preceding comparison. A device for implementing such a checking method is also described.
