Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic function, and a wearable computer with optimal weight distribution and stretchable arms.

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.

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

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.

Embodiments are directed to eyewear. The eyewear may include a frame, a left cord, a right cord, and an adjustable coupler. The frame may have a left end piece and a right end piece. Each of the left and right end pieces may have one or more apertures. The left cord has a proximal end portion and a distal end portion. The proximal end portion of the left cord may extend through at least one of the one or more apertures in the left end piece. The right cord has a proximal end portion and a distal end portion. The proximal end portion of the right cord may extend through at least one of the one or more apertures in the right end piece. The adjustable coupler may couple the left cord to the right cord.

A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.
