    • Aspects of the present invention provide dynamic focusing systems and dynamic zoom systems having no moving parts. The dynamic focusing systems can include an electro-active lens, a fixed focus lens in optical communication with the electro-active lens and a focal plane. The dynamic zoom systems can include a first electro-active lens, a second electro-active lens, a fixed focus lens, and a focal plane. The electro-active lenses of the present invention can have an adjustable optical power to provide variable focusing capability. The dynamic focusing systems and dynamic zoom systems can include a controller for altering the adjustable optical powers of the electro-active lenses. The dynamic focusing systems can focus on objects at various distances based on the controlled optical power of the included electro-active lenses. The dynamic zoom systems can provide magnification and de-magnification based on the controlled optical power of the included electro-active lenses.

    • Aspects of the present invention provide systems, methods, and apparatuses for providing coarse vision correction tuning capability, fine vision correction tuning capability, and/or high-order aberration correction capability. An optical device or lens assembly of the present invention can include one or more conventional lenses, one or more fluid or liquid lenses, one or more electro-active lenses, or any combination thereof. The optical device or lens assembly can be mechanically, adhesively, or magnetically coupled to a phoropter or can be built into the phoropter as an integrated add on lens assembly. Electro-active lenses within the lens assembly of the present invention can provide a range of optical powers including—positive, neutral (plano), and negative optical powers—that can be discretely or continuously tuned or adjusted. A wired or wireless remote unit can be used to control the lens assembly of the present invention.
