OPTICAL PROTECTIVE HYDRODYNAMIC DEVICE Russian patent published in 2025 - IPC G02C7/10 

FIELD: optics.

SUBSTANCE: invention relates to optical devices, including for protective and attack goggles or screens in order to improve vision during aimed fire and effective protection of eyes. Optical protective hydrodynamic device 1 is made in the form of a movable protective element 2 in the form of a mini-screen from the optical medium of lens 8, conjugated and balanced along the axis of rotation with an oscillatory circuit made as an extended sealed bubble tank 3 with a given volume of liquid 4 and air, in the ratio that is sufficient for free movement of the liquid inside the bubble tank and the occurrence of limited oscillatory movements on axial 6 or other movable connection of the device with a base in the form of goggles 7, screens or protective helmet when the level of liquid horizon 5 in the tank changes, wherein axial connection 6 can be made at any level relative to the surface of liquid 5 and at any distance relative to the housing of the bubble reservoir and the movable protective element.

EFFECT: provides preservation of cleanliness of part of the sight lens, creating optimum conditions for conducting aimed firing, and also provides protection of eyes in glasses with sight holes in the lens.
