摘要:
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.

The invention provides methods for designing ophthalmic lenses, and lenses produced by this method, which lenses corrects both low order and high order wavefront aberrations of the lens wearer's eyes.
摘要:
A ball retrieving apparatus is formed with a tubular storage chamber on which is mounted a gateway mechanism at the lower end thereof. The gateway mechanism is formed of a cylindrical housing having a passageway therethrough for alignment with the tubular storage chamber engaged therewith. The housing incorporates a ring of spring-loaded detent balls that are biased to project into the passageway to restrict the effective diameter thereof. Balls being retrieved are pressed into the housing to retract the detent balls against the biasing force until the ball has passed the ring of detent balls. The biasing force on the detent balls will retain the collected balls within the tubular storage chamber until the chamber is emptied. The ball retrieving apparatus can be sized to receive any type of sports activity ball.
