Method for determining an updated visual correction need for designing a new vision correcting device

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.
