Abstract: A system for determining refraction features of both first and second eyes of a subject including a light field display device, a system of localization of the positions of the first and second eyes of the subject, the light field display device generating a first light field directed selectively toward the first eye, and, respectively, a second light field directed selectively toward the second eye, control circuitry that adjusts the first light field as a function of at least a first refraction parameter associated with at least a first optical aberration for the first eye and the control circuitry adjusting said second light field as a function of at least a second refraction parameter associated with at least a second optical aberration for the second eye.

Abstract: Disclosed is a method for determining a filter for an ophthalmic lens to be placed in front of the eye of the wearer, the filter being able to improve or maintain the visual comfort and/or the visual performances of the wearer. The determination method includes: a step of measuring a variable representative of sensitivity of the eye or both eyes of the wearer to a characteristic light flow, and a step of determining at least one optical characteristic of the filter according to the representative variable measured.

Abstract: A photocurable composition which can be used to manufacture a three-dimensional object that is formed by stacking a plurality of layers on top of each other, from which the three-dimensional object having excellent transparency, a high glass transition temperature, and a high hardness can be formed, and which exhibits a high curing rate. The photocurable composition is a photocurable composition used to manufacture a three-dimensional object that is formed by stacking a plurality of layers on top of each other. The photocurable composition contains a monofunctional monomer having a polycyclic aliphatic group, a polyfunctional monomer, an alcohol, and an acylphosphine oxide photopolymerization initiator.

Abstract: The disclosure relates to methods, controlling units, eyeglasses, computer programs and computer-readable storage media for controlling an optical transmission of a variable transmission ophthalmic lens. The method includes receiving from a light sensor a measured illuminance of the environment of a wearer, computing a change of illuminance measured during a predetermined time interval, comparing the computed change of illuminance with a first threshold, when the computed change of illuminance is greater than the first threshold, implementing first command configured for varying the transmission of the variable transmission ophthalmic lens from initial transmission value corresponding to a current transmission value to a first target transmission value, according to a first variation profile comprising a first phase during which the transmission overshoots the first target transmission value, and a second phase during which the transmission returns to the first target transmission value.

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.
