Claims17
A method of treating contact lenses which comprises contacting the lens with an aqueous solution comprising a material composed of (a) a hydrophobic core having at least three carbon atoms and (b) at least three hydrophilic polyethylene oxide chains attached to the core, and wherein said material is selected from the group consisting of an ethoxylated glucose derivative, an ethoxylated derivative of glycerin, an ethoxylated derivative of sorbitol, and mixtures thereof.
A method of treating contact lenses which comprises contacting the lens with an aqueous solution comprising:
- a material composed of (a) a hydrophobic core having at least three carbon atoms and (b) at least three hydrophilic polyethylene oxide chains attached to the core;
- and
- a cationic cellulosic polymer.
