FIELD: ophthalmology.SUBSTANCE: fluid filled adjustable contact lens comprises front and rear surfaces; lens chamber located between them comprising a front membrane, attached to the rear membrane, reservoir fluidly connected to the lens chamber actuator configured to transfer fluid back and forth between the lens chamber and the reservoir; sensor configured to sense movement from the user and transmit a control signal processor configured to actuate the actuator upon receipt of the control signal from the sensor. Front and rear surface of the lens are configured for neutralization of astigmatism, created by deformation of the lens chamber. Fluid transfer changes the optical power of the lens by changing the curvature of the front membrane, that results in change of curvature of the front surface of the lens. Reservoir and actuator are arranged inside the lens.EFFECT: technical result - possibility of setting up lens continuously in required range of optical power.8 cl, 4 dwg |
