Patent Images
1. 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 said adjustable optical system;
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;
an image analyzer for determining a sharpness of said reflected image; and
an optical system controller for generating said control signal to regulate the adjustment of said at least one focus parameter of said adjustable optical system to increase said sharpness of said reflected image.
