The invention relates to an eyeglass joint for an eyeglass frame with a first joint part assigned to a rim of the eyeglass frame, and a second joint part assigned to an eyeglass temple of the eyeglass frame, wherein the joint parts are movably connected to each other by means of at least one spring element attached to both joint parts, wherein the spring element preferably has a closed annular shape and/or is rubber-elastic. Furthermore, the invention relates to a joint set, an eyeglass frame, an eyeglass frame set, and the use of a spring element.

According to the invention, spectacles include a frame front (2) onto which the temples (3a, 3b) are attached, characterized in that the temples are detachably connected to the frame front by means of a magnet (7).

The present invention generally concerns a one piece eyewear having concealed hinges made via 3D printing. More specifically, the invention includes a U-shaped hinge with irregular offsets that are blended parametric curves that connect a lens frame to temple bars. The hinge is most flexible at its parabolic cross section and allows the temple bars to open and close, mimicking the rotational and stress bearing properties of traditional mechanical hinges. The eyewear is sculpted in a 3D modeling program that exports digital instructions for rendering the hinges, lens frame, and temple bars as a single construct by a 3D printer. The one piece eyewear is capable of accepting prescription or non-prescription lenses. A method for making the eyewear having concealed hinges is also disclosed.

Users exploiting near-to-eye (NR2I) displays for augmented reality and/or correction of low vision are typically wearing these NR2I displays for specific tasks or for extended periods of time, potentially all their time awake. Conflicting tradeoffs between user comfort and minimal fatigue and strain during use, ease of attachment, minimizing intrusiveness and aesthetics should be concurrently balanced with providing an optical vision system that provides the user with a wide field of view, high image resolution, and a large exit pupil for eye placement with sufficient eye clearance. Accordingly, embodiments of the invention provide NR2I displays meeting these conflicts whilst also addressing the inherent variations between user in respect of their head dimensions, head and eye geometry, as well as adapting the displayed content to reflect the user's task at-hand, visual defects or degradations, visual focus and intent upon various regions-of-interest within their field of view. Such HMDs providing enhanced user experiences.

Provided is a hingeless eyewear in which, in a case where a pair of temples is locked to each other and folded, it is possible to prevent one temple from being unintentionally disengaged from the other temple.

An eyewear 1 includes a front 10 and a pair of temples 11 connected to the front 10 in a hingeless manner. A front region 50 of each of the temples 11 has a protrusion portion 60 that protrudes in an inner direction of the temple 11. A rear region 51 has a groove portion 80 that penetrates the temple 11 in an in-out direction and a recess portion 81 that is disposed on an outer side surface of the temple 11 and communicates with the groove portion 80. The pair of temples 11 is configured such that the groove portion 80 of one temple 11 is fitted into a portion of the front region 50 of the other temple 11 that is closer to a front 10 side than the protrusion portion 60 and is further slid along the front region 50 to a protrusion portion 60 side, so that the protrusion portion 60 of the other temple 11 is accommodated in the recess portion 81 of the one temple 11.
