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: Disclosed is a method for determining a parameter of an optical device including at least an optical lens, the method including: an optical system providing step, during which an optical system including a visual target, the optical device and an image acquisition module is provided in an initial configuration state, a parameter determining step during which a parameter of the optical device is determined based on the blur level of the images of the visual target acquired by the image acquisition module through the optical device in at least two different configuration states.

Abstract: Disclosed is a method for determining a parameter of an optical equipment including an optical lens including permanent markings and being mounted in a spectacle frame, including: positioning the optical equipment is before a pattern in a first position; positioning a portable electronic device including an image acquisition module in a second position so as to acquire an image showing together the pattern seen through at least part of the optical lenses of the optical equipment in the first position and at least part of the spectacle frame of the optical equipment in the first position; detecting the permanent marking on the optical lens using the image acquired by the image acquisition module of the portable electronic device in the second position; and determining at least one parameter of the optical equipment based on the position of the permanent marking.
