Silicone hydrogel contact lenses are provided which have reduced modulus and contact angle properties, and which have acceptable wettabilities for use in daily wear and extended or continuous wear applications.

Silicone hydrogel contact lenses

PROBLEM TO BE SOLVED To provide an ophthalmic lens, which can be more safely worn, that is, to provide a material, which is transparent and has high oxygen permeability and a high hydrophilic property, and to provide a novel monomer to be a raw material thereof. SOLUTION A hydrophilic polysiloxane macromonomer contains polyoxyethylene as a hydrophilic side chains in a polysiloxane main chain, wherein transparency, oxygen permeability, and hydrophilic properties of the material are controlled by regulating the length of the polysiloxane main chain, the length of the hydrophilic polyoxyethylene side chains, and the number of the side chains.

Hydrophilic polysiloxane macromonomer, and production and use of the same

A hydrophilic polysiloxane macromonomer containing polyoxyethylene as a hydrophilic side chains pendant to a polysiloxane main chain for imparting transparency, oxygen permeability, and hydrophilic properties to a contact lens is disclosed. The properties of the material are controlled by regulating the length of the polysiloxane main chain, the length of the hydrophilic polyoxyethylene side chains, and the number of the side chains.

A solution for preserving and/or disinfecting a contact lens characterized by containing polylysine.
