Patent

CA 2597855

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.

L~invention concerne des dispositifs et des procédés de contrôle de myopie. Les dispositifs et les procédés dérivent de la découverte par les inventeurs de la relation entre le travail de près, les forces appliquées à l~AEil par les paupières et la myopie. Les dispositifs comportent une lentille de contact comprenant une région qui disperse la force appliquée à l~AEil par une paupière. Les dispositifs englobent également un dispositif conçu en mesurant les premières aberrations de front d~onde d~un AEil avant un travail de près et en mesurant les secondes aberrations de front d~onde de l~AEil après un travail de près. Les procédés comprennent un procédé de contrôle de la myopie comme l~identification de changements optiques associés au travail de près et la correction des changements optiques avec un dispositif optique.
