The present invention is directed to a topical ophthalmic composition for a liquid comprised of clear colloidal polar nanolipids delivered in submicron sized particles, aqueous colloidal lubricants, aqueous polymers, emulsifies, and a unique stabilizing buffer system, which undergoes a liquid-gel phase transition in the eye. Said composition is designed to deliver advanced eye lubricants, protect the three (3) layers of corneal film from dryness, and provide a unique system of Dry Eye treatment that addresses and treats all three layers of corneal tear film. Said composition is further designed to provide a superior delivery system of various Active Pharmaceutical Ingredients (APIs), and/or anti-infective/antibiotic/anti-fungal agents, accepted as safe and efficacious for ophthalmic use.
