System for assisting in determining a final optical prescription for a subject and associated method

A system for assisting in determining a final optical prescription for a subject, comprising:

• at least one measurement device configured to objectively measure a set of refraction data on eyes of the subject or on corrective lenses of the subject, said set of refraction data comprising at least one of:
• for each said eye or each said corrective lens of the subject, a sphere value representative of a myopia or hyperopia power of the eye or the corrective lens;
• for each said eye or each said corrective lens of the subject, an axis value representative of an axis of astigmatism of the eye or the corrective lens;
• a pupillary distance value representative of the distance between a center of pupils of the eyes of the subject;
• two half-pupillary distance values representative of a deviation between the center of the right and left pupils respectively of the eyes of the subject, and a plane formed by a center of a nose of the subject;
• and
• an identifier allowing the measured refraction data to be associated with a measurement of the eyes or corrective lenses of the subject;
• an evaluation device, configured to propose at least one set of evaluation corrective lenses for the subject to a practitioner, each said set of evaluation corrective lenses corresponding to an evaluation optical prescription, for determination, by the subject, of a final optical prescription, from the at least one proposed set of evaluation corrective lenses,
• the evaluation device determining the at least one proposed set of evaluation corrective lenses as a function of the measured set of refraction data,
• wherein the at least one measurement device comprises a means for producing an image encoding the set of measured refraction data and for transmitting said image from the at least one measurement device to the evaluation device, said means for producing an image comprising at least an encoding processor, configured to create the image based on the set of measured refraction data,
• the evaluation device comprising a means for reading the image, configured to obtain the set of measured refraction data from the read image.
