Abstract: The invention provides a method, system, and device for connecting loose trial lenses into a virtual reality (VR) headset, augmented reality (AR) headset, or other head mounted display. The system consists of two components: First, a component that is installed mechanically into the headset and which remains in the headset throughout the duration of its use. Second, a component which holds loose trial lenses and can be inserted and removed from the headset at will. The two components may connect to each other mechanically, magnetically, electrically, or by other means. In the magnetic system, both components contain embedded magnets that allow the second component to hold loose trial lenses inside the headset magnetically.

Abstract: A virtual reality system can perform a visual field test for detecting an ocular disorder. The system can include a display unit and a virtual reality headset. The virtual reality headset can be in wireless communication with the display unit. The virtual reality headset can include a display screen configured to present a test scene to a patient to thereby detect the ocular disorder.

Abstract: A light tracking apparatus mounted on a movable vehicle includes a power source for the light tracking apparatus. There is at least one light receiving means for detecting reflected light from the surface marking and surrounding background. A computing means is included for processing the difference between intense and weak reflected light from the pavement marking providing a signal indicating a significant change in light intensity, and an alarm means responding to said signal for indicating a that change in the light intensity.

Abstract: The present invention relates to a binocular indirect ophthalmoscope for observing and examining the fundus of the human eye. The ophthalmoscope of the invention integrates an electro-optic imaging system in the viewing optics of the ophthalmoscope. Advantageously, such integration permits the stereoscopic observation of the retina and choroid by employing radiation ranging from the near ultraviolet to the infrared, including the visible spectrum. A light source illuminates a desired portion of a patient's fundus and the radiation reflected in response to the illuminating radiation is brought to focus to produce an aerial image of the fundus. A pair of ophthalmoscope lenses then magnify and image the aerial image along two different optical paths onto imaging sensors, such as charge coupled devices (CCDs) and image cameras, or image tubes such as image intensifiers.
