FIELD: chemistry.
SUBSTANCE: invention relates to silicone polymers and hydrogels obtained therefrom. Disclosed is a silicone polymer, having a whole light transmissivity of at least 90 %, obtained from reactive components containing (i) at least one silicone component, which is a (meth)acrylate ester, and (ii) 2-hydroxyethyl acrylamide. Also disclosed is a silicone hydrogel containing said polymer; a contact lens and an ophthalmic device made from said materials.
EFFECT: disclosed material enables to obtain an ophthalmic device with faster curing to achieve a high level of light transmission and high oxygen permeability.
