An ophthalmic device for reducing dyslexia effects for a wearer including a frame intended to be worn by the wearer and a blinking illuminating element coupled to the frame comprising at least one light source configured to emit light in front of the wearer's head so as to lighten a medium observed by the wearer, said at least one light source being configured to be successively switched on and switched off at a predetermined frequency when the blinking illuminating element is activated.

Method of controlling an active filtering device comprising an active filter and a filter controller arranged to control the active filter, the method comprising:

Method of controlling an active filtering device

A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film.

An imaging device including an illumination module including at least one emitter for emitting at least one excitation beam, a scanning and injection module including an image guide, a proximal end and a distal end of which are linked by a plurality of optical fibers, and a scanning and injection optical system configured to alternately inject the at least one excitation beam into an optical fiber of the image guide from the proximal end of the image guide, and a detection module including at least one detector for detecting at least one luminous flux collected at the distal end of the image guide. At least one of the illumination module and the detection module is optically conjugated with the scanning and injection module by a conjugating optical fiber.

Modular imaging system, modules for this system and method implemented using this system

A miniaturized optical head provided to equip the distal end of a beam of flexible optical fibers scanned by a laser beam, is designed to come in contact with a sample and to excite the sample confocally. This optical head includes elements for correcting spherical aberrations and focusing members. The focusing members include: at least a first lens (L) of high convergence associated with a spherical or hemispherical lens (L) arranged at the distal end of the optical head, and elements for correcting the axial and lateral chromatic aberration provided with a single divergent lens () whose curvature is substantially centered on the pupil of the optical fiber beam and arranged at the exact distance for this pupil for which the conditions of lateral achromatization coincide with the conditions of axial achromatization; this divergent lens being associated with a second convergent lens (L) in the form of a doublet (L).

Miniaturized optical head with high spatial resolution and high sensitivity, especially for fibred confocal fluorescence imaging

An imaging device includes an illumination module comprising at least one emitter for emitting at least one excitation beam; a scanning and injection module comprising an image guide, a proximal end and a distal end of which are linked by a plurality of optical fibers; a scanning and injection optical system configured to alternately inject the at least one excitation beam into an optical fiber of the image guide from the proximal end of the image guide; a detection module comprising a detector for detecting a luminous flux collected at the distal end of the image guide, wherein at least one of the illumination module and the detection module is optically conjugated with the scanning and injection module using a conjugating optical fiber.
