A method of assembling an adjustable fluid-filled lens assembly comprising biaxially tensioning an elastomeric membrane to a surface tension of greater than 180 N/m, typically greater than 1000 N/m; thermally conditioning the tensioned membrane, e.g., for one hour at a temperature of about 80° C., to accelerate relaxation of the membrane; mounting the membrane to a peripheral support structure whilst maintaining the tension in the membrane; assembling the mounted membrane with one or more other components to form an enclosure with the membrane forming one wall of the enclosure; and thereafter filling the enclosure with a fluid. The membrane may be formed from an aromatic polyurethane, and the fluid may be a phenylated siloxane. In some embodiments, the membrane is able to hold a substantially constant surface tension of at least 180 N/m for a period of at least 12 months.

Disclosed herein is an eyewear, optionally without nose supports/pads. The eyewear comprises a frame to receive a pair of lens; a pair of side supports adapted to pivot about a zygomatic region of a wearer’s face; and a pair of temple cables arranged to contact ear portions the wearer; wherein each of the temple cable is adjustable so as to provide a counter-weight to the frame.

The accessory eyeglasses retention device secures eyeglasses to a wearer's head. The accessory eyeglasses retention device includes an elongated body extending between a front end and a back end, and an adjustment mechanism, including a canal within the elongated body, and configured to directly and firmly grip a temple of the eyeglasses and adjustably position the elongated body relative to the temple. An angled retainer is at the back end of the elongated body, extending and angled in a medial direction towards a user's head and to contact the user's head when the eyeglasses are worn on the wearer's head, and configured to securely retain the eyeglasses in a desired location on the wearer's head.

The present invention relates to an extension and strap for eyeglasses. More particularly, the present invention relates to an apparatus for holding eyeglasses onto a user's face that allows for eyeglasses to be put on and removed with only one hand. The present invention also includes a method of using the strap of the present invention to put on, retain in place, and remove eyeglasses using only one hand.

An accessory eyeglasses retention device is integrally formed as a single elastomeric piece to secure eyeglasses to a wearer's head. The accessory eyeglasses retention device may include an elongated body extending between a front end and a back end, an adjustment mechanism including a first elastic strap and a second elastic strap, for example, longitudinally spaced apart on the elongated body and configured to hold a temple of the eyeglasses and adjustably position the elongated body relative to the temple. An angled flap is at the back end of the elongated body, extending and angled in a direction towards a portion of the wearer's head when the eyeglasses are worn on the wearer's head, and configured to securely retain the eyeglasses in a desired location on the wearer's head. Also, a lanyard attachment feature may be included at the back end of the elongated body and configured to attach the elongated body to an eyeglasses lanyard.

An adjustable looped-cord goggle attachable to a helmet is provided. The goggle includes a goggle frame having a first side and a second side, one or more channels formed along an internal periphery of frame, and an elastic cord adapted to form a first loop and a second loop. A first end of the cord fastened to a first position on the first side of the frame and a second end exits through a second position on the first side of the frame forming the first loop. A remaining portion of cord is passed through the channels to reach the second side of the frame. Further, the second end of the cord is passed through a third position and exits at a fourth position on the second side of the frame forming the second loop. The first loop and second loop fasten the goggle frame to the helmet.

A magnetic attraction type lens-replaceable eyeglasses, comprising a frame and lenses. A connector for fixedly connecting the lenses to the frame is disposed at a bridge of the frame. The connector is detachably connected to the frame. The connector and the frame are in magnetic attraction cooperation. Fixing pins capable of penetrating through the lenses and used for limiting the swing of the lenses are disposed on the side, in contact with the lenses, of the connector. By using the detachable connector, the lenses are fixed to the frame. By means of magnetic attraction cooperation, the lenses can be relatively easy to replace. Meanwhile, by using a design of positioning pins, it can be ensured that the lenses mounted on the frame will not swing or shift.
