Patent

CA 2637053

A method and apparatus are disclosed for controlling optical aberrations to alter relative curvature of field by providing optical devices and methods comprising the repositioning of peripheral off-axis focal points relative to the retina to produce stimulus for influencing the progression of refractive error while simultaneously controlling the position of the central focal point near to the retina to provide clear central vision and simultaneously providing zones of controlled peripheral defocus and other optical aberrations to improve peripheral vision for select directions of gaze.

L'invention concerne un procédé et un appareil pour réguler des aberrations optiques afin de modifier la courbure relative de champ grâce à des dispositifs et procédés optiques comprenant le repositionnement de points focaux périphériques décalés par rapport à la rétine pour produire des stimulus destinés à influencer la progression d'une erreur de réfraction tout en régulant simultanément la position du point focal central proche de la rétine pour obtenir une vision centrale nette et obtenir simultanément la régulation de zones de défocalisation périphérique et d'autres aberrations optiques pour améliorer la vision périphérique dans des directions sélectionnées du regard.
