System and associated methods of use for rapid assessment of visual field integrity. In one embodiment, the device comprises a frame that rests near a patient's eyes with pinpoint lights or mechanical stimuli that act as visual stimuli mounted at locations within the frame and in the patient's peripheral visual field. A vantage point in front of the frame allows an operator to view the patient's eyes during assessment, enabling the operator to maximize the accuracy during both in person and telemedicine assessments. The lights or mechanical stimuli are positioned such that they are visible to patients with a wide range of interpupillary distances, enabling the use of a single-size device for all patients.

A headgear mount system includes a mechanical assembly comprising at least one mount assembly, at least one tilt / flip assembly, and at least one interpupillary distance (IPD) adjustment assembly.

Disclosed are multi-axis articulating binoculars configured to enhance functionality, depth perception, and maneuverability in both daylight and low-light environments. The binoculars include left and right optical barrels mounted to a central body through hinges that provide articulation along multiple axes, enabling adjustment of interpupillary distance (IPD) and expansion of the effective field of view (FOV). In certain embodiments, horizontal articulation of the barrels allows outward angling to increase the combined FOV beyond conventional fixed systems, providing situational awareness comparable to quad night vision devices at reduced cost and weight. The binoculars further incorporate a dual-mode infrared (IR) illumination system with selectable wavelengths, such as 850 nm and 1064 nm, to provide adaptability across different environmental and operational conditions. Structural components may be formed from lightweight carbon fiber composites to improve handling, strength-to-weight ratio, and thermal performance, thereby enabling extended, reliable operation in demanding field applications.

This invention belongs to the field of smart glasses technology, specifically relating to a magnetic lens structure for smart glasses. It includes a glasses body and an adjustable nose pad assembly connected to the glasses body. A refractive lens assembly is detachably connected to the nose pad assembly, allowing the refractive lens assembly to move synchronously with the adjustment of the nose pad assembly. By directly mounting the refractive lens assembly to the nose pad assembly, this invention ensures that when the nose pad assembly is adjusted, the refractive lens assembly moves with the nose pad assembly, rather than with the smart glasses body, thus maintaining the interpupillary distance of the refractive lens and improving wearing comfort.

A second driving unit can change an interval between the pair of display units. An interpupillary distance adjustment unit adjusts the interval between the display units by the second driving unit in accordance with a detection result obtained by the interpupillary distance detector. After interpupillary distance adjustment is performed, a diopter adjustment unit performs diopter adjustment related to the display unit by the first driving unit.

This invention discloses an ophthalmic examination device for ophthalmic care, belonging to the field of ophthalmic examination technology. It includes a base with a support structure for supporting the patient's chin, a pupillary distance adjustment component, and two sets of symmetrical eye-expanding mechanisms. The pupillary distance adjustment component drives the two sets of eye-expanding mechanisms to move horizontally synchronously, adapting to the patient's interpupillary distance. Each eye-expanding mechanism includes a horizontally positioned examination cylinder with a convex lens mounted at its front end. Compared with existing technologies, this invention has the following advantages: Through the cooperation of the pupillary distance adjustment component and the linkage limiting structure, pupillary distance adjustment and head limiting are completed synchronously without additional calibration, significantly improving operational efficiency. Furthermore, the eye-expanding mechanism uses a single-set drive to achieve synchronous and equal-amplitude opening of both eyelids. Combined with a worm gear self-locking and elastic fitting design, it solves the compatibility problem between pupillary distance adjustment and eyelid opening transmission, while avoiding rigid contact damage and preventing eyelid slippage, thus meeting the needs of efficient clinical diagnosis and treatment.
