Evaporative dry eyes, caused by an unstable or deficient lipid layer of the tear film (the top outer most layer) that affects almost 90% of dry eye patients. 

Hycosan Shield replaces the function of the lipid layer, forming an outer shield over the surface of the tear film, reducing evaporation of the watery layer.

• Spreads easily due to low surface tension properties

• Replaces the outer lipid layer of the tear film

• Helps to indirectly re-establish the tear film's watery layer by preventing its evaporation

• Increases tear film thickness, as well as lipid layer thickness, over time

• Preservative & phosphate free
