FLUID-FILLED LENSES AND FILLING MECHANISMS THEREOF Russian patent published in 2017 - IPC G02B1/06 

FIELD: optics.

SUBSTANCE: invention relates to fluid-filled lenses and can be used in ophthalmology, photonics, digital telephones, cameras, microelectronics. Disclosed actuator for a sealed, fluid-filled lens comprises: a housing; a reservoir disposed within housing; a compression arm having a first end, which is fixed, and a second end of which is not fixed. Compression arm is disposed adjacent to reservoir and bends and compresses reservoir. Actuator of sealed, liquid-filled lens comprises a slider arranged to slide inside housing and arranged so that it adjoins compression arm, wherein sliding of slider from first end of compression arm to second end of compression arm causes, slider to push second end of compression arm, thereby compressing reservoir.

EFFECT: providing adjustment of optical force for compensating for change of natural depth of focus of eye which depends on pupil size of wearer of glasses, and which, in turn, depends on ambient illumination level.
