Presbyopia treatment and anti-myopia spectacles comprise a negative refractive element facing an object and a positive refractive element facing a patient eye. The negative refractive element has a central zone with a strong negative refractive power. The positive refractive element has a central zone with a less strong positive refractive power. The front focal point of the central zone of the positive lens does not have to overlap with the front focal point of the central zone of the negative lens. The negative refractive element and the positive refractive element are axially separated by a relatively small distance such that the combination of the two refractive elements is compact enough to be made into an easily wearable spectacle. For myopia progression control, at least one portion of the paracentral and/or peripheral zone of at least one of the two refractive elements has a relative add power with respect to that of the central zone such that the image of an off-axis distant or intermediate object is formed in front of a corresponding paracentral or peripheral retina area to create myopic defocus on the corresponding retina area.

An auxiliary magnifying system for use in connection with a pair of glasses, includes: a. a positionable mounting fixture, said positionable mounting fixture comprising: i. an elongated body having ii. a pair of engageable mounting wings thereupon, b. an axle retained therein about which said rotatable mounting wing may be rotated; c. a mount capable of retaining a positioning arm thereupon; d. a flexibly deformable arm, one end of which is capable of being retained in said mount on said elongated body; e. a bracket capable of being mounted on the other end of said flexibly deformable arm; and f. a lens mountable in said bracket.

An assembly with removable and replaceable wire arms is used to attach different nose pad configurations to eyeglass frames for enhanced versatility. A plate with front and back surfaces and opposing side edges mounts on the bridge portion of the eyeglass frames. Opposing right and left wire members extending downwardly from the side edges of the plate terminate in a coupling mechanism adapted to receive a nose pad. The wire members are manually bendable, enabling a user to independently adjust the distance between the nose pads and the distance of the nose pads from the eyeglass frames. The coupling mechanisms may include holes to receive nose pads with posts, and screws to hold the posts in position, or barbed fins to receive nose pads with slots that engage with the barbed fins. The coupling mechanisms may receive physically separate nose pads or nose pads interconnected through an upper nose rest.

Provided are an eyeglass-mounted image display device capable of adjusting the interval between, height of, and elevation/depression angle of viewers detachably attached to eyeglasses, and an image display system using the eyeglass-mounted image display device.

The eyeglass-mounted image display device includes: viewers 7 displaying an image from an endoscope serving as an image output apparatus; and eyeglasses 1 to which the viewers 7 are detachably attached via an attaching member 8. The viewers 7 are disposed in front of lenses 3 of the eyeglasses 1, and the interval between, height of, and elevation/depression angle of the viewers 7 are adjustable with the attaching member 8.

This invention relates to ophthalmic lens for spectacle comprising a primary glass, a secondary glass, a main chamber and a membrane configured to separate the volume of the main chamber in a first chamber and a second chamber.

A device can include glasses including one or more lenses that permit a wearer a broad view of the environment from a first perspective and contact members having one or more contact-surfaces formed to secure the glasses to a head of the wearer while the wearer is wearing the device. The device can include one or more loupes, each loupe including a redirection member structured to redirect image light that is received by the loupe; one or more magnifying members structured to magnify the image light; a viewport structured to allow passage of the magnified image light. The loupe is secured through one of the lenses such that the magnified image light is presented though the viewport to an eye of the wearer while the wearer is wearing the device.

A user-wearable illumination assembly comprising eyeglass frames supporting a pair of lenses, a mounting structure on a bridge of the eyeglass frames, a headlamp removably coupled to the mounting structure, a battery housing removably coupled to the headlamp, and a battery inside the battery housing.

Head-mounted accessories for surgeons and medical/dental practitioners are equipped with no-touch, hands-free controls. A voice-activated headlamp includes a controller operative to send a signal to control a light source in accordance with a voice command received through an integrated or remote microphone. The voice command and control may be speaker-dependent or speaker-independent, and the head-mounted unit may include an interface to a computer for voice-command training or other purposes. The head-mounted unit includes a memory for storing the voice commands. The invention may be used to control other medical/dental accessories such as a head-mounted video camera, in which case the controller is further operative to at least turn the video camera ON or OFF. More preferably, a controller is additionally operative to control the focus or zoom of the video camera in accordance with a voice command.

A hands-free binocular device. A pair of eyeglasses has two temples. A telescopic section is mounted to each eyeglass temple. The hands-free binocular device includes lenses for magnifying images and light path redirecting devices for controlling the light path to the eyeglass lenses. Light from an image being observed flows through the magnifying lenses and is redirected by the light path redirecting device. The image is magnified and viewable by a user. The user can shift his gaze upward to view the magnified image or look down from the magnified image to view a non-magnified image. In one preferred embodiment the light path redirecting devices are prisms. In another preferred embodiment the light path redirecting devices are mirrors.

A method for determining filtering capabilities of a magnification device suitable for providing protection from light when viewed through the magnification device is disclosed. The filtering capability of the magnification device is determined based at least one of an input power of the inputted light signal, a magnification level of the magnification device and an orientation of the filtering within the magnification device. Further disclosed is an lighting system that generates a light, which when reflected into the magnification device is prevent from causing damage to a user's eyes based on the selection of the filtering system disclosed herein.
