LENS DESIGN WITH OPTICAL FORCE PROFILE OF ARBITRARY SHAPE AND METHOD OF PREVENTING AND/OR SLOWING PROGRESSION OF MYOPIA Russian patent published in 2017 - IPC G02C7/04 A61F2/16 

FIELD: physics.

SUBSTANCE: ophthalmic lens includes the first zone in the center of the lens; the first peripheral region continuously extending from the center and having an optical force different from the optical strength of the zone at the center and the second peripheral region continuously extending from the first peripheral region and having an optical power different from the optical power of the first peripheral region. A continuous optical power profile of an arbitrary shape is provided, having a visual efficiency substantially equivalent to the visual effectiveness of a monofocal lens, and having a depth of focus and a reduced sensitivity to image quality on the retina, which allows to slow, inhibit or prevent the progression of myopia. The said continuous profile corresponds to the mathematical expression indicated in the claims.

EFFECT: improving the correction of the vision in the distance with increasing the depth of focus and reducing the sensitivity to image quality.
