Ophthalmic eyeglass correcting both foveal vision and peripheral vision
摘要:
An ophthalmic eyeglass (1) is adapted for correcting both the foveal vision and the peripheral vision of a wearer. An image portion formed in the foveal zone of the wearer's retina is thus sharp, at the same time as another image portion is also sharp, which is formed on the retina away from the foveal zone, by light rays that are oblique to the line of sight of the wearer. To this purpose, the eyeglass comprises a central zone (10) and first (21) and second (22) regions that alternate in a peripheral zone (20) of said eyeglass. First parameters of the eyeglass in the central zone and in the first regions are adapted so as to correct the foveal vision of the wearer and second parameters of the eyeglass in the second regions are adapted for correcting the peripheral vision of said wearer.
