FIELD: polymer production and polymer materials. SUBSTANCE: invention provides a novel formulation capable of being subjected to radical polymerization, which contains mixture of at least one (meth)acrylate bifunctional monomer(s) of the type depicted by general formula A: 
(formula A) and/or A': 
(formula A') and at least one bifunctional alkene monomer(s) of the type depicted by general formula B: 
(formula B) and/or B': 
(formula B'), and/or B": 
(formula B"), in which formulas 
vary within a wide range. Invention also concerns resins prepared by polymerization of indicated formulations and ophthalmological products manufactured in part or exclusively of these resins. These products can, if necessary, have photochromic properties. EFFECT: improved optical characteristics of resins. 25 cl, 5 tbl _
