Abstract
Over 1 billion people worldwide including more than 100 million people in the United States of America alone suffer from an age-related eye condition known as presbyopia. Presbyopia is caused by a loss of focal accommodation of the crystalline lens inside the eye as the lens stiffens with age. A presbyopic person has reduced or very limited ability to focus on objects placed at different distances. The utilization of conventional fixed, uniform or graded power eyeglasses for presbyopia correction is generally unsatisfactory as fixed power eyepieces cannot provide any accommodation restoration. In this paper we will discuss an implementation of lightweight adaptive-optics auto-focusing eyeglasses that augment the accommodation range of vision thus partially or fully cancelling the accommodation loss caused by presbyopia and restoring normal vision function.
