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.
Claims20
A system for modifying the vision of a subject, comprising:
- an adjustable optical system having an adjustable spherical focus and a control signal input adapted to receive a control signal for controlling the adjustment of at least one focus parameter of the adjustable optical 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.
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 the adjustable optical system and including a fluid lens, wherein the fluid lens includes an interface between two immiscible fluids;
- 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.
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 the adjustable optical system and including a fluid lens having an elastically deformable shell surrounding an inter-lens spade, wherein the fluid lens is adjustable by adjusting the pressure or volume of a fluid in the inter-lens space;
- 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.
