Provided is an eyeglass frame that includes a hinge with which a reduction in size and a reduction in weight can be achieved, and stable open/close operations can be performed over a prolonged period of time. The eyeglass frame includes a lens holding portion 2, a temple 3, and a hinge 5 that enables pivoting of the lens holding portion 2 and the temple a The hinge 5 includes a terminal portion 21 of the lens holding portion 2, a terminal portion 31 of the temple 3, and a coupling portion 4 that couples the two terminal portions. The terminal portion 31 of the temple 3 is selectively positioned with respect to the coupling portion 4 at a position when the temple 3 is completely open and at a position when the temple 3 is folded.

Aspects of the present invention relate to a head-worn computer having a see-through computer display, a frame mechanically adapted to hold the see-through computer, a first side arm pivotally attached to the frame and adapted to hold the head-worn computer in place on a head of the user, wherein the first side arm comprises a temple section and an ear horn section and the temple section further comprising a compartment adapted to contain a battery, wherein the battery powers the see-through computer display.

A adjustment sound-generating temple includes a hinge member, a connecting seat and a temple. The hinge member has a saw teeth and a pivot pins on one surface, the connecting seat is provided with an insert slot on one end and an extension rod on the other, which has two saw teeth on each of its inner side. The temple is assembled by combining the hinge member and the connecting seat. The completed temple is then connected to the frame, forming a spectacle that makes clicking sounds when adjusting the temple's angle. The clicking sounds help to enhance the quality of the spectacle as a whole.

Glasses for retarding myopia progression is provided, and include a frame (10) and glasses legs. Each of the glasses legs includes a first leg (19) and a second leg (21). The second leg (21) is connected between the frame (10) and the first leg (19), the second leg (21) is movable telescopically in relation to the first leg (19). In movement of the frame (10) relative to eyeballs (100, 200) from a primary position to a secondary position stretched, a relationship between an effective degree and a lens degree is denoted by: P.sub.2=P.sub.1/(1−d.sub.2P.sub.1). P.sub.1 is an actual lens degree at the primary position, P.sub.2 is an effective lens degree at the secondary position, and d.sub.2 is a spacing between the primary position and the secondary position, the spacing meets: 0<d.sub.2<60 mm.

Aspects of the present invention relate to a head-worn computer, comprising a removable and replaceable adjustable nose bridge assembly, wherein the adjustable nose bridge assembly has at least three user adjustable features to adapt the adjustable nose bridge assembly to the user's nose, wherein a first adjustment of the at least three user adjustable features is adapted to move the adjustable nose bridge up and down relative to a lens of the head-worn computer, wherein a second adjustment of the at least three user adjustable features is adapted to rotate a nose pad of the adjustable nose bridge about an axis substantially perpendicular to a top frame of the head-worn computer, and wherein a third adjustment of the at least three user adjustable features is adapted to flare the nose pad to the side of the axis.

Eyeglass frames that are both adjustable fore and aft on each side, and that allow each lens to be raised or lowered slightly so that the glasses fit well with both lenses at the same vertical level. Embodiments of the present invention includes a small ratchet and hinge on each arm that allows the forward part of the frame to rotate slightly up or down. In addition, in other embodiments, both legs can have a sliding length adjustment that allows the leg to fit snugly behind the ear on each side with the lens in the correct fore and aft position. Some embodiments of the present invention have both features present, while other embodiments have only one or the other feature.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

A frame includes: a pair of temples; a connecting bar connecting respective ends of the pair of temples; at least one hanging shaft located at a middle of the connecting bar; nose pads fixed to the hanging shaft; a slide attached to the hanging shaft for a sliding movement; a pair of lens-holding frames vertically slidable in front of the connecting bar, the lens-holding frames being each configured to hold vertically arranged upper and lower lenses; and a bridge coupling the lens-holding frames. The bridge is attached at a level lower than a center of the lower lens in each of the lens-holding frames, and the lens-holding frames are slidable for a distance at least corresponding to a distance between a center of the upper lens and the center of the lower lens.

A set of customizable eyeglasses allows customers to make adjustments to a width of eyeglass frames relative to one another, a width of eyeglass temples relative to one another, a depth of eyeglass temples from the eyeglass frames, and/or a length of the nose bridge support from the customer's face. The customer could input one or more measurements into a system, such as a width and depth of a face, and a company could manufacture the eyeglass components in accordance with the measurements to provide rough adjustments to the eyeglasses to be sent to the customer. When the customer receives the eyeglasses, the customer could then make fine adjustments to the eyeglasses to further customize the fit.

Provided is a pair of glasses with a ventilated structure, mainly including an upper frame, a lens unit and a lower frame. The upper frame is provided with a lens groove and an inserting seat. The inserting seat is provided with inserting groove with a downward notch. The inserting seat is provided with an adjusting unit. The adjusting unit has a plurality of adjusting holes arranged up and down. Each side of the upper frame is provided with a combination hole. The lens unit is arrange in the lens groove, and is provided with a plurality of air-permeable holes at the upper end of the lens unit. Each side of the lower frame is provided with a joint section. The joint section is detachably coupled to the combination hole of the upper frame. Two sides of the lower frame can be operatively connected or disassembled with relative to the upper frame. The lower frame is further provided with an inserting section to be inserted into the inserting groove. The inserting section is provided with a positioning convex part operatively embedded in one of the adjusting holes of the adjusting unit to for a positioning. By positioning the position of the positioning convex part relative to each adjusting hole, the air-permeable holes of the lens are hidden or exposed on the upper frame.
