FLEXIBLE DYNAMIC MOVING ZONES FOR CONTACT LENSES Russian patent published in 2016 - IPC A61F2/16 G02C7/04 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. An ophthalmic device sized and shaped to fit a user's eye comprises: a corrective lens with an optic zone having an upper portion, comprising a lens assembly for far vision correction, a lower portion comprising a lens assembly for near vision correction with a peripheral zone surrounding the optical zone, a front surface and back surface; and a flexible moving zone integrated into the corrective lens between the front and back surfaces in the peripheral zone and designed to move the lens on an eye. The flexible moving zone is configured in the form of a projection made of a deformable material with is deformed under the action of blinking eyelid pressure, thereby at least one flexible moving zone is configured and positioned so as to interact to the user's eyes as that a downward view is accompanied by at least one flexible moving zone interacting to the eyelids so as to match the lens assembly for near vision correction with an eye pupil, whereas in at least an upward or straight view, the lens assembly for far vision correction matches with the pupil.

EFFECT: using the presented invention enables smooth and accurate linear lens movement over the eye surface.
