What Is TrueTear?

The TrueTear™ device provides a temporary increase in tear production during use. TrueTear causes your eyes to produce their own natural tears using tiny pulses of energy. These pulses activate a natural response through a clever technology called neurostimulation.

The TrueTear tip stimulates a nerve in the nasal cavity with tiny pulses of energy, sending out nerve signals to the brain. The brain then sends nerve signals to the tear glands surrounding the eyes to temporarily increase tear production. The glands surrounding the eyes react and temporarily produce real tears.
