As a substitute for tears your eye will be kept wet. The eyedrops work by forming a viscous eye gel via the carmellose sodium solution. It produces a transparent, lubricating and moistening film on the surface of the eye and is used as artificial tears. Carmellose clings to the surface of the eye and is therefore not washed out of the eye as quickly as a lot of alternative lubricating eye drops are.
