The application discloses an optical shielding film, a full-spectrum medical protective eyecup and a preparation method thereof, and relates to the field of protective eyecups. The optical shielding film comprises a nano optical coating, the nano optical coating comprises a plurality of composite layers, the composite layers comprise a metal layer and a dielectric layer, the thickness ratio of the metal layer and the dielectric layer is 1: (3-10), the metal layer comprises at least one of aluminum, silver and chromium, and the dielectric layer comprises at least one of silicon dioxide, titanium dioxide, aluminum oxide and zirconium oxide. The application utilizes the metal layer to provide a high-reflection interface, utilizes the dielectric layer to adjust phase matching, can reflect visible light and near-infrared light with a wavelength of 500-1200 nm at each layer interface, and makes all reflected light interfere constructively at the front surface of the substrate and be reflected back with extremely high efficiency, while the transmitted light is greatly inhibited due to destructive interference, realizing high-efficiency shielding of the wide-band light with the wavelength, and being suitable for the preparation of a flexible protective eyecup in medical photoelectric treatment.

The utility model relates to functional spectacles technical field, concretely relates to a dual -purpose protective glasses, can give consideration to daily leisure use and outdoor travel protection, the glasses body includes the mirror frame and glasses leg, the glasses leg articulates on the bending part of mirror frame both ends, the protection spare links in the bending part and glasses leg junction, the protection spare includes the insertion part, first protection piece and second protection piece, first protection piece and second protection piece are fixed respectively in the insertion part both sides, first protection piece is attached the mirror frame upper side edge setting, is used for covering the clearance of mirror frame upper side and user's face, second protection piece is attached the mirror frame outside edge setting, is used for covering the clearance of mirror frame both sides and user's face, the utility model aims at providing a kind of protective glasses with " outdoor protection " and " daily leisure " dual function, and support protection spare quick, convenient disassembly.

The application discloses a sealed anti-fog breathable protective goggles, belongs to the technical field of goggles, and comprises a goggles main body, a breathable protection assembly, a driving shell and a conduction assembly. The ring-shaped air bag is arranged in the arched breathable groove, the air bag is inflated to block the channel, and the air bag is deflated to restore the ventilation, so that the flexible switching of the sealed and ventilated states is realized. The ring-shaped air bag is uniformly supplied with air or drawn back through the flow guide pipe and the driving pipeline. The whole driving is completely manually operated, and an external power supply is not needed. The conduction assembly utilizes the phase change material in the energy absorption and heat conduction box to collect the forehead surface heat, and the heat is conducted to the transparent high-heat-conducting film on the lens through the energy guide rod, the integrated plate, the energy guide column and the fog reduction frame, so that the fog layer condensation is inhibited, and the coating and the electric heating scheme are replaced. The sealed and anti-fog are synchronously triggered by the single-time dialing of the rotating handle through the air pressure linkage of the sealing rod and the driving pipeline, so that the operation is simple, and the function response is always consistent.

This utility model relates to the field of eyewear technology, and in particular to a protective eyewear and its control system. It includes a frame and two mounting brackets. The frame is equipped with a supplementary light and a protective lens with laser band protection function. A first polarizing element is arranged in the light output path of the supplementary light, which is used to supplement the visual field of the protective eyewear. The mounting brackets are provided with a mounting cavity for housing a second polarizing element. This utility model utilizes the supplementary light to enhance the illumination intensity of the visual field, offsetting or reducing the attenuation effect of the protective lens on non-target laser bands, allowing the operator to more clearly distinguish target objects in the visual field and reducing the operator's eye strain. Simultaneously, due to the gradual adjustment of the polarization angle, the light presented to the operator's visual field changes gradually, allowing the operator to better adapt to the transition, further reducing the operator's eye strain and workload.

This utility model belongs to the field of eyewear technology and discloses a lens-protective eyeglass, including a support frame assembly. The support frame assembly has temple 1 and temple 2 on both sides, and a connecting assembly at its upper end. The connecting assembly includes a connector, a tension spring fixedly connected to the end of the connector, and a connecting unit movably connected to the upper end of the connector. Through the cooperation of the connector and connecting unit, this utility model allows the connecting block to move away from the first and second support frames, releasing the connector from its engagement with the connector. This causes the first support frame to move away from the second support frame, creating a gap between them. This facilitates lens removal, achieving the effect of cleaning the lenses without the need for tools or force, and preventing damage to the lenses or frames during removal.
