Abstract: A method for evaluating the visual acuity of a person using a mobile device having at least a front camera and a screen, the method including a user positioning step during which the user of a mobile device positions himself in front of a mirror at a predefined distance d/2, a mobile device positioning step during which the mobile device is positioned with the front camera of the mobile device facing the mirror, a distance measuring step during which a distance d between the front camera of the mobile device and a virtual image of the mobile device in the mirror is measured, a displaying step during which the screen of the mobile device displays optotypes, and an evaluation step during which the visual acuity of the user is evaluated.

Abstract: A method for determining at least one optical parameter of an eye of a person comprising displaying at least two sharp images on a retina of the eye of the person, the at least two images comprising a target and being carried by two light beams focused substantially in the plane of a pupil of the eye at at least two different positions, adapting a parameter of the target in each image based on feedback of the person relative to the change of the parameter of the target in the image, and determining the at least one optical parameter of the person's eye based on the adaption of the parameter of the target in each image.

Abstract: A method and associated instrument in which an optical system is switched from a first to a second refractive power states, to provide a first, and then a second refraction correction to an eye of a subject, the switching being carried on without interrupting a light beam coming from a target object and transmitted by the optical system to the eye of the subject. The switching is carried on in order to circumvent an intermediate refraction correction that is in between said first and second refraction corrections, or with a speed higher than a given limit.

Abstract: An optometry device for testing an individual's eye (E) comprises an imaging module (10) adapted to produce a first image at a variable distance for the individual's eye (E), a beam splitter (26) arranged to combine the first image and a second image for the individual's eye (E), and a screen (22) facing the beam splitter (26). A mirror (24) is arranged in combination with the screen (22) to produce the second image to be visible by the individual's eye via the beam splitter (26).
