About this trial
This is an interventional basic science trial for Dry Eye Syndromes focused on measuring Dry Eye Disease
Eligibility Criteria
Inclusion Criteria:

- Have not worn contact lenses for at least 7 days prior to the screening visit and are willing to forego the use of contact lenses for the duration of the study
- The participant should be literate, able to speak English, and able to complete questionnaires independently
Exclusion Criteria:
- Chronic or recurrent epistaxis, coagulation disorders or other conditions that, in the opinion of the investigator, may lead to clinically significant increased bleeding
- Nasal or sinus surgery (including history of application of nasal cautery) or significant trauma to these areas
- Cardiac demand pacemaker, implanted defibrillator or other implanted electronic device
- Corneal transplant in either or both eyes
- Current enrollment in an investigational drug or device study or participation in such a study within 30 days of entry into this study
- Women who are pregnant, planning a pregnancy, or nursing throughout the study
