Hormonal deficiencies or changes

Low blink rate

Blinking is critical in spreading tears over the surface of the eye and stimulating tear production. A chronic low blink rate is associated with dry eye symptoms. Computer use, reading, and watching TV are the three activities most commonly associated with a low blink rate.

We use our Tear lab and Inflammadry to analyze tear chemistry for dry eye diagnosis and treatment.
