6. Occlusion of the ocular puncta within 30 days prior to Screening/Baseline (Visit 1)
7. Have worn contact lenses within 3 days prior to Screening/Baseline (Visit 1) or planned wear during the study
8. Use of topical prescription products for dry eye, including topical ocular anti inflammatories (eg, cyclosporine, lifitegrast), corticosteroids, MIEBO® (perfluorohexyloctane ophthalmic solution), or TRYPTYR® (alcotremon ophthalmic solution) within 30 days prior to Screening/ Baseline (Visit 1)
