Abstract

Various embodiments of methods and systems for improving and enhancing vision are disclosed. Adjustable lenses or optical systems may be used to provide adaptive vision modification. In some embodiments, vision modification may be responsive to the current state of the user'"'"'s visual system. Certain embodiments provide correction of the subject'"'"'s near and far vision. Other embodiments provide enhancement of vision beyond the physiological ranges of focal length or magnification.

Claims

1-116. -116. (canceled)

117. A system for modifying the vision of a subject, comprising:

an adjustable optical system having a control signal input adapted to receive a control signal for controlling the adjustment of at least one focus parameter of a lens system; and

at least one image detector adapted to detect in real-time an image reflected from a retina of an eye of the subject and capable of generating as an output a reflected image signal containing information about the focus condition of said reflected image.

118. The system of claim 117, further comprising a mounting structure for positioning said lens system with respect to an eye of said subject.

119. The system of claim 117, wherein said image detector is located on or about said lens system.

120. The system of claim 118, wherein said image detector is located on said mounting structure.

121. The system of claim 118, wherein said mounting structure comprises an eyeglass frame.

122. The system of claim 118, wherein said mounting structure comprises a helmet-mounted frame, or a component of a hat, a head-adornment, or an item of head-centered apparel.

123. The system of claim 117, wherein said adjustable optical system comprises a fluid lens.

124. The system of claim 123, wherein said fluid lens comprises an interface between two immiscible fluids.

125. The system of claim 123, wherein said adjustable optical system comprises a lens having an elastically deformable shell surrounding an inter-lens space, and wherein adjusting said lens comprises adjusting the pressure or volume of a fluid in said inter-lens space.

126. The system of claim 117, wherein said adjustable optical system comprises an electroactive lens.

127. The system of claim 117, wherein said adjustable optical system comprises a compound lens.

128. The system of claim 117, wherein said adjustable optical system has an adjustable spherical focus.

129. The system of claim 117, wherein said adjustable optical system has at least one of an adjustable cylindrical focus or axis of cylindrical orientation.

130. The system of claim 117, wherein said adjustable optical system has an adjustable magnification factor.

131. The system of claim 117, wherein said adjustable optical system has an adjustable intensity in at least one visible spectral band.

132. The system of claim 117, further comprising a transmitter configured to transmit at least a portion of said reflected image signal wirelessly from said image detector to an image analyzer.

133. The system of claim 117, further comprising a transmitter configured to transmit said control signal to said adjustable optical system for reception at said control signal input.

134. The system of claim 117, wherein said control signal input is configured to receive a digital signal.
