Claim 2:
3. A method of treating ocular discomfort in a subject in need thereof, wherein said ocular discomfort is associated with a contact lens, the method comprising ophthalmically administering to the subject with said contact lens in an eye of the subject an effective amount of a solution comprising at least one water-soluble polymer, liposomes, and an aqueous carrier, thereby effecting boundary lubrication by reducing a friction coefficient of said contact lens, wherein a concentration of phospholipids of said liposomes in the solution is in a range of from 0.5 mM to 500 mM, and wherein said at least one water-soluble polymer comprises a non-ionic polymer selected from the group consisting of a polyvinylpyrrolidone and a polyethylene glycol, an average molecular weight of said at least one water-soluble polymer is in a range of from 3 kDa to 10 MDa, and a concentration of said at least one water-soluble polymer in said solution is in a range of from 0.01 to 10 mg/ml.
