  • Patent number: 10534201
    Abstract: The present invention is to provide a full-frame adhesive anti-fog film structure, comprising: an anti-fog film, which has a front side and a back side opposing the front side; and an adhesive, which is disposed at an edge of the back side and arranged along the edge so as to be frame-shaped. The anti-fog film of the present invention is attachable to a planar, cylindrical or spherical lens through the full frame-shaped adhesive so that not only can the anti-fog film be fully attached to the lens but the full attachment of film also prevents bubbles from forming between the two attached surfaces. Also, an airtight space is formed between the full-frame adhesive anti-fog film structure and the lens to stop heat transfer and prevent fog from being formed, so as to not only provide good vision to users but also reduce the chance that the user will fall prey to an accident if the user's view is blocked.

  • Patent number: 10509155
    Abstract: Systems, devices, and methods that implement waveguides in curved transparent combiners that are well-suited for use in wearable heads-up displays (WHUDs) are described. Waveguide structures with in-couplers and out-couplers are integrated with curved eyeglass lenses to provide transparent combiners that substantially match the shape, size, and geometry of conventional eyeglass lenses and can, in some implementations, embody prescription curvatures to serve as prescription eyeglass lenses. The waveguides and in-/out-couplers are planar or curved depending on the implementation. WHUDs that employ such curved transparent combiners are also described.

  • Patent number: 10488678
    Abstract: An eye-mounted device includes a contact lens and an embedded camera, which for convenience will be referred to as a femtocamera. The front aperture of the femtocamera faces away from the user's eye so that the image sensor in the femtocamera detects imagery of a user's external environment. The femtocamera optics has a folded optical path, which is advantageous for fitting the femtocamera into the limited space within the contact lens. In one design, the optics for the femtocamera is based on a two mirror design, with a concave mirror followed by a convex mirror. In an alternate design, the optics for the camera includes an imaging lens near the front aperture.

  • Patent number: 10459255
    Abstract: An eye-mounted display is used to enhance vision of a user with visual impairment. Images of a user's unimpaired view of a surrounding environment are captured. These image are modified to compensate for the user's visual impairment. For example, the captured images can be magnified, an angular extent of the captured images can be compressed, or a contrast of the captured images can be enhanced. Also, the captured images can be modified by including identification of an object, a face, or an emotion. For a captured image including text, the text in the captured images can be modified. The eye-mounted display projects the compensated images onto the user's retina. When the user's retina has a damaged section, the eye-mounted display projects the compensated images away from the damaged section.

  • Patent number: 10444800
    Abstract: A system for protecting electronic headset components from sunlight is provided. The headset is secured to a user's head for use and includes an electronic display, a lens, and a battery all secured to a frame structure. The frame structure includes a mask portion which is sized and shaped to fit snugly against the user's face, and a strap for holding the mask to the face. According to the invention, a moveable shield is mounted to a portion of the frame structure, either directly or indirectly, and is designed to move between a stowed position, wherein light from the display may pass freely through the lens to the user's eyes, during use, and a blocking position, wherein sunlight is prevented from passing through the lens and reaching, and damaging, the delicate electronic display. The shield may be sized and shaped to fit both lenses, or each lens, and may pivot or slide between positions, either automatically, or manually.

  • Patent number: 10441161
    Abstract: A system and a method for holographic refraction eye testing device is disclosed. The system renders one or more three dimensional objects within the holographic display device. The system updates the rendering of the one or more three dimensional objects within the holographic display device, by virtual movement of the one or more three dimensional objects within the level of depth. The system receives input from a user indicating alignment of the one or more three dimensional objects after the virtual movement. The system determines a delta between a relative virtual position of the one or more three dimensional objects at the moment of receiving input and an optimal virtual position and generates prescriptive remedy based on the delta.
