Abstract: A system for determining a personalized value of an optical feature of a corrective ophthalmic lens which is intended to be worn in front of an eye of an individual for correcting his vision, the system including: a trial optical corrective device adapted to be place in front of an eye of an individual, the trial optical corrective device providing a correction to an individual complying with an initial value of an optical feature; an eyewear adapted to be placed in front of the trial optical corrective device worn by the individual and adapted to immerse the individual in a virtual environment, the eyewear being designed to present, in the virtual environment, a visual task to the individual adapted to determine an adjustment value; a processing unit programmed calculate a personalized value of the optical feature based at least on the initial value and the adjustment value.

Abstract: The disclosed method uses a headset to be placed on the head of an individual, an image capture apparatus, and a sensor adapted to measure a value of a first parameter linked to the luminous intensity of a light present in the environment of the individual with a wavelength included in a predetermined wavelength range. The method includes the following steps: a) capturing at least an image of the environment with the image capture apparatus; b) measuring the measured value of the first parameter; c) displaying on a screen of the headset a corrected image based on the captured image, taking into account the measured value and the optical feature of the lens. An associated electronic device is also described.
