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.

Eye glasses with a lightened frame are made using a process in which at least one part of the eye glass frame is made lighter by making at least one cavity in it.

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.

In an information system and a method for providing information in correlation with light that is incident on an eye, a pair of spectacles includes a holographic element that is supported in front of the eye of a wearer of the spectacles. An optical scanning device detects light that is incident on the eye via the holographic element.

An improved ophthalmic instrument for in-vivo examination of a human eye including a wavefront sensor that estimates aberrations in reflections of the light formed as an image on the retina of the human eye and a phase compensator that spatially modulates the phase of incident light to compensate for the aberrations estimated by the wavefront sensor Optical elements create an image of a fixation target at the phase compensator, which produces a compensated image of the fixation target that compensates for aberrations estimated by the wavefront sensor. The compensated image of the fixation target produced by the phase compensator is recreated at the human eye to thereby provide the human eye with a view of compensation of the aberrations the human eye as estimated by the wavefront sensor. The phase compensator preferably comprises a variable focus lens that compensates for focusing errors and a deformable mirror that compensates for higher order aberrations. The optical elements preferably comprise a plurality of beam splitters and a plurality of lens groups each functioning as an afocal telescope. In addition, instruments and systems are provided that exploit these capabilities to enable efficient prescription and / or dispensing of corrective optics (e.g., contact lens and glasses).
