Abstract:
An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.
