APPARATUS AND METHOD FOR EYESIGHT REHABILITATION

摘要

The invention provides apparatii and methods for eyesight rehabilitation using optical devices having controllable optical power for improving the eyesight of a user. The optical device (10) comprises liquid lenses (14) having curvature that changes in accordance with the amount of transparent liquid confined within the lenses. Changes in the inclination of the user's head causes, by physical means or sensors, the curvature of the liquid lens (14) to change while rendering the liquid lenses autofocus features. Lenses made of electroactive material can be used also in order to control the optical power of the lens. According to the method used, the user wearing the lenses is challenged to look at objects positioned in different locations for a predetermined time. The time in which the lenses are focused is adjusted to be slightly longer then the natural accommodation of the user's eyes when he turns from one object to the other.
