7 results about "Blurred vision" patented technology

The application discloses an image processing method and device, which comprises the following steps: collecting a video in front of a vehicle through a camera; processing the video collected by the camera, so that the processed video is clearer; and projecting the processed video on a windshield glass of the vehicle, so that a driver can see the road condition information more clearly through the projected picture on the windshield glass in a blurred vision scene, the accident rate is reduced, and the driving safety is improved.

This invention discloses an anti-fogging structure for gastrointestinal endoscope lenses, belonging to the field of endoscopy technology. The anti-fogging structure includes an instrument body. A controller, adjustment mechanism, and water supply mechanism are fixedly mounted on the surface of the instrument body. A connecting tube is fixedly connected to the surface of the instrument body, and a probe is fixedly connected to the end of the connecting tube. The connecting tube and the probe are used to insert into human organs. The adjustment mechanism is used to adjust the position of the probe. The lens body is fixedly mounted on the surface of the probe. A heating tube is tightly fitted to the surface of the lens body, forming a highly efficient heat conduction structure. When sterile water is delivered to the heating tube through the outlet tube, the heating tube rapidly heats up and evenly transfers heat to the surface of the lens body, avoiding blurred vision caused by fogging. Furthermore, using sterile water as the medium avoids the risk of secondary contamination and meets medical-grade safety standards, balancing functionality and hygiene requirements.

Provided is an XR device using an event camera for divers. The XR device according to an embodiment may generate an external RGB image and an external event image by photographing an external environment, may perform video frame interpolation with respect to the external RGB image by using the external event image, and may display the interpolated external RGB image on a transparent display. Accordingly, clearer underwater images may be provided to divers in a low-light underwater environment in which visibility is significantly reduced due to the refraction of water, blurred vision, turbid water, flow of currents.

The application discloses a kind of composite plant extract eye drops for relieving eye fatigue and a preparation method thereof, and relates to the technical field of ophthalmic preparations.The eye drops of the present application use lutein, zeaxanthin, blueberry extract, peppermint essential oil and borneol as fat-soluble active ingredients, and use phospholipid and poloxamer 188 as a composite nanocarrier, in combination with sodium hyaluronate, sodium chloride and a buffer system, a bacteriostatic system to form the eye drops.The present application uses a film hydration combined with high-pressure homogenization process to produce clear and transparent, thermodynamically stable eye drops, which solves the problems of low solubility, easy oxidative degradation and poor bioavailability of fat-soluble ingredients, improves the concentration and retention time of active ingredients in the eye, and the synergistic effect of various plant extracts can effectively relieve the symptoms of eye fatigue caused by long-term eye use, such as dryness, acid swelling, blurred vision and ciliary spasm, without eye irritation and with high stability.

This application relates to the field of vehicles, and particularly to laminated glass, its manufacturing method, and vehicles. The laminated glass includes an outer glass plate, an inner glass plate, and an intermediate layer disposed between the outer and inner glass plates. The intermediate layer includes at least one nonlinear optical composite layer, each of which independently includes a polymer matrix and a nonlinear optical medium dispersed within the polymer matrix. The laminated glass of this application can maintain high light transmittance even in low light conditions without affecting driving activities. When encountering strong glare, it reduces light transmittance, protecting the driver from glare-induced blindness, blurred vision, or visual discomfort. After the strong glare disappears, it restores high light transmittance.

This invention provides a portable eyewash station, relating to the field of eyewash stations, comprising: a cleaning cap threadedly connected to the upper end of a cleaning bottle; a cleaning head fixedly connected to the upper end face of the cleaning cap; a cleaning cup fixedly connected to the upper end face of the cleaning cap; a rubber ring fixedly connected to the upper end face of the cleaning cup; a sliding plate slidably connected to the inner side of the cleaning bottle; a piston fixedly connected to the upper end face of the sliding plate; and a fixing plate fixedly connected to the inner side of the lower end of the cleaning bottle. Through the design of this invention, eyewash is effectively cleaned, ensuring the user's health, improving the user experience, and solving the problem that existing portable eyewash stations, due to their fixed placement, cause excessive tearing when harmful substances splash into the eyes, leading to blurred vision, difficulty in finding the eyewash station in time, and delays in optimal eyewash cleaning.
