2. Have a history of ocular surgical intervention or trauma within 12 weeks prior to Visit 1 or planned for the period of the study.
3. Have presence of any active ocular inflammation (e.g., uveitis, allergic conjunctivitis, ocular rosacea, or iritis), other than acute adenoviral conjunctivitis.
4. Have clinical signs or presence of an ocular infection other than acute adenoviral conjunctivitis (e.g., bacterial, fungal or other ocular viral infection, such as herpes).
5. Have the presence of corneal subepithelial infiltrates at baseline.
6. Have a history of recurrent corneal erosion syndrome, ulcerative keratitis or dry eye, including meibomian gland dysfunction and other ocular surface diseases.
7. Have presence of blepharitis, lid abnormality, significant inflammation of the lid margin, or ptosis.
8. Have lacrimal duct obstruction in either eye.
9. Have presence of any other clinically significant findings during the slit lamp exam that may interfere with study parameters or otherwise confound the data as determined by the investigator
10. Have any clinically significant retinal or optic nerve findings (as observed in the non-dilated fundus exam) or prior diagnoses in either eye that may interfere with study parameters or otherwise confound the data as determined by the investigator).
11. Have used any topical ocular or systemic anti-viral or topical ocular or systemic corticosteroid within 7 days of enrollment and do not plan to start any topical ocular or systemic anti-viral during study duration.
