Americans live with chronic dry eye. The standard treatment is single-use plastic vials, daily, for life.
The body already knows how to make tears.
The trigeminal nerve is the largest cranial nerve, with branches reaching from the nose to the lacrimal gland. Stimulating the external nasal branch activates a natural reflex arc that triggers tear production without drugs or drops.
This pathway — the trigeminal-lacrimal reflex — has been validated in FDA-cleared devices. NeuroStim refines the approach with an external, non-invasive, two-minute protocol.
