Dry eye is a result of a loss of water from the tears on the eye surface that makes the tears too salty or “hyper-osmotic.” Hypo-osmotic TheraTears Lubricant Eye Drops help put back the lost water, lowering the high salt concentration, so that they not only wet but also rehydrate dry eyes.
In addition the tears are an electrolyte solution specially designed to protect the eye surface. With TheraTears we replicated and patented the electrolyte balance of the human tear film so that each drop of every TheraTears Lubricant Eye Drops provides the special salt balance, the electrolyte balance, needed for the health of the eye surface.
And finally, each drop of TheraTears provides a special, highly lubricating form of carboxymethylcellulose, to maximize the instant relief from the dryness, stinging and burning, and sandy-gritty irritation of dry eye. So by rehydrating, protecting and lubricating the eye, TheraTears provides soothing, long-lasting and cumulative dry-eye relief that really works!
