METHOD OF DETERMINING AN EYE PARAMETER OF A USER OF A DISPLAY DEVICE
First Claim
1. Method for determining an eye parameter, for example a geometrical eye parameter, of a user of a display device, the method comprising:
- a display device providing step, during which a binocular display device is provided to the user, the binocular display device is configured to display independently images towards the two eyes of the user,an image display step, during which an image is displayed to the user when using the display device,a display parameter modifying step, during which at least one parameter of the display device is modified so as to modify the quality of the perceived image,wherein the display parameter modifying step is repeated until image subjective quality of the perceived image is perceived as optimal by the user, andan eye parameter determining step during which an eye parameter is determined based on the parameter of the display device.

Abstract
Disclosed is a method for determining an eye parameter of a user of a display device, the eye parameter relating to a dioptric parameter of an ophthalmic lens to be provided to the user, the method including: a display device providing step, during which a binocular display device is provided to the user,—an image display step, during which an image is displayed to the user when using the display device; a display parameter modifying step, during which at least one parameter of the display device is modified so as to modify the virtual display distance of the perceived image, wherein the display parameter modifying step is repeated until image subjective quality of the perceived image is perceived by the user as optimal; and an eye parameter determining step during which an eye parameter is determined based on the parameter of the display device.

12. A system for determining an eye parameter of a user of a display device, the system comprising:
-
display device providing means, configured to provide to a user a binocular display device, the binocular display device being configured to display independently images towards the two eyes of the user, image display means, configured to display an image to the user when using the display device, display parameter modifying means, configured to modify at least one parameter of the display device so as to modify the quality of the perceived image, wherein the display parameter modifying means are further configured to modify the at least one parameter until image subjective quality of the perceived image is perceived by the user as optimal, and eye parameter determining means configured to determine an eye parameter based on the parameter of the display device.
