Abstract: The present disclosure includes optical articles comprising a lens having first and second lens surfaces and a protective layer having first and second protective surfaces that is coupled to the lens such that the first protective surface is disposed on the second lens surface. The optical article can comprise a plurality of convex or concave optical elements defined on the second lens surface or the first protective surface. The protective layer can have a maximum thickness larger than a maximum height of each of the optical elements such that the protective layer encapsulates the optical elements.

Abstract: The present invention relates to an optical device usable in a head-mounted display which comprises a light conducting element and at least one wafer, and to a head-mounted device which is configured to provide an informative display of augmented reality for a wearer of the head-mounted device and which comprises such an optical device. This optical device (1) comprises: a light conducting element (4) which has two first and second opposite main faces (4a and 4b) and which inputs and conducts by total internal reflections a light (6) received from the light source (5) and partially outputs it out of said element, at least one wafer (2, 3) which comprises an internal surface (2a, 3a) facing a said first main face of said light conducting element, and interposition means in contact with said first main face and said internal surface and defining a gap (11a, 11b) optically isolating said element. According to the invention, said interposition means comprise a peripheral sealing arrangement (10a, 10b) which extends along its peripheral length between and in sealing contact with a peripheral area (2aa, 3aa) of said internal surface and a facing zone (4aa, 4ba) of said first main face, at least one portion of said sealing arrangement exhibiting a locally reduced optical coupling with said first main face to preserve said internal reflections at said at least one portion toward the inside of said element.

Abstract: An optical device adapted for a wearer includes an emitting system, a first wafer and a gap. The emitting system includes a halt conducting element configured to output a light through an exit face of the light conducting element towards an eye of the wearer. The first wafer includes an internal face facing the light conducting element. The gap is arranged between at least the exit face of the light conducting element and the wafer. The internal face of the wafer includes at least a curved surface facing the exit face and has a curvature greater than 0 D.

Abstract: Disclosed is a method implemented by computer for determining a lens blank intended to be used for the manufacturing of a finished optical article. The method includes: —a virtual volume data determining step, during which virtual volume data are determined based at least on finished optical article data representative of the volume of the finished optical article and over-thickness data representative of over-thickness requirements, the virtual volume data are determined so that the virtual volume defined by the virtual volume data includes the volume of the finished optical article volume of the finished optical article and the over-thickness, —a lens blank determining step, during which a lens blank is determined based on the virtual volume data so as to include the virtual volume defined by the virtual volume data.
