Apparatus, including a housing that is configured to be mounted in proximity to a human eye. The apparatus further includes optics that is retained by the housing and that is configured to focus optical radiation from a scene to an image viewable by the human eye. The apparatus also includes a tunable wavelength filter that is retained by the housing and that is configured to sequentially filter the optical radiation from the scene by a first wavelength and by a second wavelength different from the first wavelength.
摘要:
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 slip-resistant eyewear system comprising an eyewear frame generally comprises a nosepiece comprising a nosepiece material configured to couple to a bridge of an eyewear frame. The frame comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second spring-loaded tension adjusters. First and second bows are coupled to first and second tension adjusters. A first bow extension element is coupled to the first bow and comprises a first fastening element at a first end of the first bow extension element and a second bow extension element is coupled to the second bow and comprises a second fastening element at a first end of the second bow extension element that is configured to mate with the first fastening element to secure the first and second bow extension elements together.

A customizable eyeglass system for use in any remote situation, and which is ideal for use in third-world countries or areas where electrical power and typical machinery for manufacturing eyeglasses is lacking. The system includes a frame with receivers for the temples to connect into and lock into place. A pair of customizable lenses is connected to the front of the frame. The lenses can be rotated to dial in the correct prescription for the patient and then locked into place as well. Thus the invention corrects near and distance vision while also correcting astigmatism. If adjustments need to be made, the patient can easily unlock the lenses, rotate them to a proper orientation for proper sight, and then lock the lenses into place again.

According to an exemplary embodiment, a loupe attachment for glasses may be provided. The loupe attachment may include a loupe and a number of optical devices such as mirrors or prisms. The loupe and the optical devices may be connected to eyeglasses and be positioned as desired. The loupe and the optical device may be connected to the glasses on number of locations and the relative position of the loupe and optical devices in the trajectory of light may be modified. According to a second exemplary embodiment, loupes may be rigidly connected to eyeglasses and a number of optical elements may be rigidly or rotatably connected to the front end of the loupe so as to reflect the field of view situated at an angle from the loupe viewing direction.

In one aspect, a device includes a frame, at least one lens coupled to the frame, at least one membrane at least partially covering at least one face of the lens, a reservoir in fluid communication with the membrane and containing fluid, and a fluid control assembly which controls fluid communication of the fluid between the reservoir and the membrane.
摘要:
The present invention relates to optical instruments, in particular to magnification loupes, such as those worn by dentists and surgeons. The invention features magnification loupes that are equipped with a light source, an energy harvesting component and an energy storage component. The invention further relates to magnification loupes comprising a light source and a polymer battery as energy storage component. In addition, the invention is directed to magnification loupes comprising a first light source emitting a light beam and a sensor structured and configured to detect a reflection of this light beam. If such a reflection is detected, a second light source mounted on the magnification loupe is turned on or off. The invention further concerns a ring made from or coated with a light-reflecting material. The invention also relates to a battery charging station on which the batteries present in the magnification loupes can be recharged.
