SET OF SOFT CONTACT LENSES Russian patent published in 2024 - IPC A61F9/00 G02C7/04 

FIELD: medicine.

SUBSTANCE: set of soft contact lenses configured to be placed on the user's eye, comprising the following: soft contact lenses that provide overall spherical power correction ranging from a negative correction in diopters to a positive correction in diopters. Moreover, each of the contact lenses in the set contains a main part with an optical zone and a peripheral zone located adjacent to the optical zone. The optical zone contains a refractive structure, which has a first power of -3D for all contact lenses in the set; and for lenses with a total power other than -3D, provide a diffractive structure located adjacent to or within the optical zone, this diffractive structure having a second power and located at a distance of 2–6 mm from the center of the lens. The first power and the second power jointly provide an overall spherical correction of the power.

EFFECT: use of this invention will expand the range of technical means.
