The invention describes augmented reality glasses (1) for medical applications configured to be worn by a user, comprising a frame (15) that supports a glasses lens (2a, 2b), wherein the frame (15) comprises an RGB lighting system comprising RGB-emitting devices (16a, 16b, 16c) configured to emit light beams (B1, B2, B3); first optical systems (17a, 17b, 17c) configured to collimate at least partially said beams (B1, B2, B3) into collimated beams (B1c; B2c; B3c); wherein the frame (15) further comprises a display (3) configured to be illuminated by the RGB lighting system (16) by means of the collimated beams (B1c; B2c; B3c); to receive first images (I) from a first processing unit (10); to emit the first images (I) as second images (IE1) towards the glasses lens (2a, 2b), wherein the lens (2a, 2b) is configured to reflect the second images (IE1) coming from the display (3) as images projected (IP) towards an internal zone (51) of the glasses corresponding to an eye position zone of the user who is wearing the glasses in a configuration for use of the glasses. The invention moreover describes an augmented reality system for medical applications on a user comprising the augmented reality glasses (1) of the invention, biomedical instrumentation (100) configured to detect biomedical and / or therapeutic and / or diagnostic data of a user and to generate first data (D1) representative of operational parameters (OP_S) associated with the user, transmitting means (101) configured to transmit the first data (D1) to the glasses (1); wherein the glasses (1) comprise a first processing unit (10) equipped with a receiving module (102) configured to receive the first data (D1) comprising the operational parameters (OP_S) associated with the user.

Optical elements such as a vari-focal lens element, a vari-focal diffractive optical element and a variable declination prism usable as spectacle lens elements and so on.

The present invention illustrates various methods of attaching a pair of eyeglass lenses or a lens shield to an eyeglass frame using magnets or magnetically attractive material. The magnetic attachment methods are beneficial because they allow the user to have interchangeable lenses or shields for indoor and outdoor use, enhancing their visual acuity during work or play. The lenses may be tinted, prescription, protective eyewear, or plano. The magnetic lenses are convenient and user friendly, allowing intuitive, tool-less interchangeability with no need to twist or stress the frame. These methods of attachment require no specific instructions or tools when the user replaces lenses.

A head mounted display (HMD) is worn on a user's head for displaying an image. A HMD is a personal see-through device designed to view still or video images or data that nonetheless permits the user to view his surroundings.

Continuous Adjustable 3Deeps Filter Spectacles are provided with lenses with continuously changeable optical densities, so that viewing of 2D movies is optimized for visualization in natural 3D. Method and means are disclosed for the continuous Adjustable 3Deeps Filter Spectacles to perform two independent optimizations to achieve optimized 3Deep visual effects on 2D movies. First they compute the optical density setting of the lenses for optimal viewing of 2D movies as 3D. Then they continuously render the lenses of the spectacles to these optical densities optimized for characteristics of the electro-optical material from which the lenses of the spectacles are fabricated. The invention works for both 3DTV and 3D Cinema theater viewing.

A spectacle lens (2) has an antireflective coating (1). The antireflective coating (1) produces a residual reflection appearing color-neutral not only under illumination with a natural daylight spectrum, but also under an illumination with an illumination spectrum deviating from the natural daylight spectrum. A method for making a spectacle lens (2) having an antireflective coating (1) is described in which an optical lens (2a) is provided and a layer sequence of layers (3, 4, 5, 6, 7, 8, 9) with alternately high and low refractive material forming the antireflective coating (1) is applied to the optical lens. The antireflective coating (1) is applied with the proviso that the antireflective coating (1) produces a residual reflection appearing color-neutral not only under illumination with a natural daylight spectrum, but also under an illumination with an illumination spectrum deviating from the natural daylight spectrum.

A method and system design and manufacture of the monogrammed faceted and stone adorned eyeglass lenses via a computer program allowing a design, intricate facet cuts and stone placement on a computer lens model. Software may utilize a touch probe or laser scanner to gather point data from a previously designed lens, converting the data to a computer model. The data is then used to send signals to an articulated robotic arm holding a lens shape. The robotic arm receives the commands from the computer, moving and rotating the lens shape against an abrasive wheel, rotating cutter blade or rotating drill thereby duplicating the facet cuts, slots notches or depressions or other designs contained in the computer lens model. Varying pressure is applied by the articulated arm and various degrees of abrasiveness of the abrasive wheel.

The base, on which the main body of a jewel is mounted, and the rear surface magnet are connected to the chain part. By this jewelry article for eyeglasses being mounted on a lens of the pair of eyeglasses, even if the main body of a jewel and the rear surface magnet fall because of their positioning difference on the lens occurred by some contacts to the main body of the jewel, the base and the rear surface magnet are in a state of being hanged down on an eyeglass frame through the chain part joined to the eyeglass frame by the joining part for an eyeglass frame.
