Abstract: An optometric testing device comprising a first shutter and a second shutter placed in front of two eyes of a patient and configured to present an activated state in which a shutter blocks the propagation of light and a deactivated state in which the shutter allows the propagation of light, a communication unit configured to communicate with a display system in order to send and/or receive a synchronization signal, and a control unit configured to command each shutter as a function of the synchronization signal so that the first shutter and the second shutter change state with a first frequency and a second frequency, wherein the control unit is configured to command each shutter so that the first frequency is different from the second frequency and/or so that a duty cycle of activation of the first shutter is different from a duty cycle of activation of the second shutter.

Abstract: Disclosed is a method for measuring the refraction of an individual by a refraction measuring appliance, including: an initial step of determining at least one initial value of a visuo-postural parameter of the individual; a step of processing the initial value in order to deduce at least one initial value of a regulating parameter of the refraction measuring appliance, the regulating parameter being associated with the visuo-postural parameter; a step of regulating the refraction measuring appliance according to the initial value of the regulating parameter; and a step of measuring the refraction of the individual by the measuring appliance regulated in this way. Also disclosed is a method for the optical design of an ophthalmic lens, and to a pair of glasses including such a lens.

Abstract: It is proposed a method for defining a design of an ophthalmic tinted lens provided with a turquoise blue ophthalmic filter. It is provided at least one optical parameter value that is prescribed with reference to a clear ophthalmic lens. At least one non-null optical power value is determined from said at least one prescribed optical parameter value. At least one reduction value is obtained. At least one reduced optical power value is calculated in function of said at least one non-null optical power value and said at least one reduction value. The ophthalmic tinted lens design is defined on the basis of said at least one reduced optical power value. Methods for defining a design of a first and a second ophthalmic tinted lens are also proposed. It is also proposed a corresponding ophthalmic tinted lens.
