A lens driver or lens driver circuitry for an ophthalmic apparatus comprising an electronic system which actuates a variable-focus optic is disclosed herein. The lens driver is part of an electronic system incorporated into the ophthalmic apparatus. The electronic system includes one or more batteries or other power sources, power management circuitry, one or more sensors, clock generation circuitry, control algorithms and circuitry, and lens driver circuitry. The lens driver circuitry includes one or more power sources, one or more high voltage generators and one or more switching circuits. Specifically, the lens driver comprises an H-bridge/H-bridge controller for providing the proper voltage, including polarity, to drive the electronic included in the ophthalmic apparatus.本文揭露一種用於一眼用設備之包含一電子系統的鏡片驅動器或鏡片驅動器電路系統,該電子系統致動一可變焦光學器件。該鏡片驅動器為一與該眼用設備結合之電子系統的一部分。該電子系統包括一或多個電池或其他電源、電力管理電路系統、一或多個感測器、時鐘產生電路系統、控制演算法和電路系統、以及鏡片驅動器電路系統。該鏡片驅動器電路系統包括一或多個電源、一或多個高壓產生器、及一或多個交換電路。具體地,該鏡片驅動器包含一H電橋/H電橋控制器,用於提供適當的電壓,包括極性,以驅動包括在該眼用設備中的電子器件。108‧‧‧鏡片電源供應器202‧‧‧PMOS開關204‧‧‧PMOS開關206‧‧‧NMOS開關208‧‧‧NMOS開關
