Abstract

Devices and methods for controlling myopia are provided. The devices and methods relate to the inventors discovery of the relationship between near work, the forces applied to the eye by the eyelids and myopia. The devices include a contact lens comprising a region that disperses force applied to the eye by an eyelid. The devices also include a device designed by measuring first wavefront aberrations of an eye before pre-near work and measuring second measured wavefront aberrations of the eye post-near work. The methods include a method for controlling myopia including identifying optical changes associated with near work and correcting the optical changes with an optical device.
