Abstract
A phoropter for use in optometric testing, utilizing a variable shaped electrowetting effect lens having an electronically adjustable shape, and through which the subject views an object. A control unit electronically adjusts the lens form according to the subject’s visual perception of the object. The adjustment can either be performed iteratively by the subject himself, or by means of the subject’s instructions to the optometrist. The lens shape can be adjusted to provide correction for high order aberrations, and is used for prescribing correction lenses, or as input information for performing vision correcting refractive surgery. Electrowetting lenses are described whose shape can be adjusted to provide correction for higher order aberrations, or even to generate a multifocal lens, either by means of a sectored electrode structure arranged peripherally around the lens clear aperture, or by means of a transparent pixelated electrode structure laid over the entire lens aperture.
