Device for automatic determination of at least the subjective ocular refraction of a patient, said device comprising: - an automatic refractor comprising an ocular device and a management unit configured to take corrective lenses from a reserve and position them in the ocular device; - a central unit configured to at least control the management unit of the automatic refractor in order to position corrective lenses in the ocular device; - a data input unit for inputting at least patient data into the central unit, - an instruction generation system controlled by the central unit and configured to automatically generate instructions to the patient at least during an eye test; - an interface system between the patient and the central unit, which is configured to directly detect indications generated in the form of gestures by the patient at least during said eye test and to transmit these instructions directly to the central unit; - an automatic refractometer configured to measure the objective ocular refraction of the patient and to transmit it to the central unit, the measured objective ocular refraction being used by the central unit to generate said at least one eye test and to determine said subjective ocular refraction; and - a frontofocometer configured to measure the corrections of the patient's eyeglass lenses and to transmit the measured corrections to the central unit, the measured corrections being used by the central unit to generate said at least one eye test and to determine said subjective ocular refraction, the central unit automatically controlling the elements of the device 1 and being also configured to automatically implement said at least one eye test, by controlling the management unit and receiving the indications generated by the patient via the interface system, and to automatically determine the subjective ocular refraction from at least said received indications and a prescription for corrective lenses, adapted to the subjective ocular refraction thus determined. - an automatic refractor comprising an ocular device and a management unit configured to take corrective lenses from a reserve and position them in the ocular device; - a central unit configured to at least control the management unit of the automatic refractor in order to position corrective lenses in the ocular device; - a data input unit for inputting at least patient data into the central unit, - an instruction generation system controlled by the central unit and configured to automatically generate instructions to the patient at least during an eye test; - an interface system between the patient and the central unit, which is configured to directly detect indications generated in the form of gestures by the patient at least during said eye test and to transmit these instructions directly to the central unit; - an automatic refractometer configured to measure the objective ocular refraction of the patient and to transmit it to the central unit, the measured objective ocular refraction being used by the central unit to generate said at least one eye test and to determine said subjective ocular refraction; and - a frontofocometer configured to measure the corrections of the patient's eyeglass lenses and to transmit the measured corrections to the central unit, the measured corrections being used by the central unit to generate said at least one eye test and to determine said subjective ocular refraction,
