FIELD: chemistry.
SUBSTANCE: invention relates to organosilicon prepolymers, containing fragments, which absorb ultraviolet (UV) radiation. Claimed is an actinically cross-linkable polymer, which contains cross-linkable polysiloxane polymer units, formed from one or several hydrophilic vinyl monomers, and double photofunctional polymer units, formed from a polymerisable compound, containing an ethylene-unsaturated group, a photoinitiating fragment and a fragment, absorbing UV-radiation, or a latent fragment, absorbing UV-radiation. Soft silicone hydrogel contact lenses, manufactured from the claimed prepolymer, are also claimed.
EFFECT: it is possible to manufacture the high-quality contact lenses with low expenditures, providing high homogeneity and reproducibility of an initial lens shape.
