Abstract: An optometry device for testing an individual's eye, includes a refraction test unit having an optical system for providing different vision correction powers close to the eye of the individual, and a display unit adapted to produce a visual test image for the individual's eye, the visual test image being visible through an exit aperture of the test unit of the optometry device. The display unit includes a screen adapted to display a test picture used in producing the visual test image and at least one optical element having an optical power. The optical element presents an active state in which it exhibits a non zero refraction power placed on an optical path of the light emitted by the screen and exiting the device through the exit aperture, and an inactive state in which it introduces no refractive power on the optical path.

Abstract: The method includes the steps of: a) illuminating the pupil of an eye of a subject by a light source of a portable electronic device, the light source being formed by a lighted area displayed on a screen of the portable electronic device; b) acquiring a picture of the pupil of the eye of the subject by an image-capture apparatus of the portable electronic device, the picture including an image of the reflection of the light source on the retina of the eye; and c) determining a refraction feature of the eye taking into account at least a geometrical feature, a positional feature or an intensity distribution of the image of the reflection. An associated portable electronic device is also described.

Abstract: A method for monitoring an evolution of a visual acuity value of a user of a digital device configured for displaying optotypes at a chosen optotype size, and computing a guessing rate corresponding to a percentage of optotypes correctly identified by a user. The method includes determining a visual acuity reference value based on at least a predefined first guessing rate threshold of the displayed optotypes at an optotype reference size, testing the evolution of the visual acuity value by displaying optotypes at a first optotype size corresponding to the optotype reference size, measuring the guessing rate of the displayed optotypes, and, if the measured guessing rate is below the first guessing rate threshold by more than a tolerance value, remeasuring the guessing rate of displayed optotypes at a second optotype size, the second optotype size being superior to the first optotype size.

Abstract: An optical device for capturing images of an eye of an individual, the optical device having a first measurement channel and a second measurement channel. The first measurement channel generates at least one first lighting beam directed toward the eye and along a first axis and to capture at least one first image of the eye when illuminated by the at least one first lighting beam. The second measurement channel is generates at least one second lighting beam directed toward the eye and along a second axis separated from the first axis by at least 5°, for example at least 10° or at least 20° and to capture at least one second image of the eye when illuminated by the at least one second lighting beam. The first measurement channel and the second measurement channel are synchronized together.
