You may qualify if:

• At least 18 years of age at the time of consent
• Able to provide written voluntary informed consent
• Must have a normal pre-corneal tear film in one or both eyes\[MC4.1\]\[AA4.2\]
• Subjects cannot have instilled any topical ocular drops (including OTC lubricant drops) within 24 hours of the study visit.
• Able and willing to follow instructions, including participation in all trial assessments and visits

You may not qualify if:

• Have any clinically significant ocular surface slit-lamp findings in either eye and/or, in the opinion of the Investigator, have any findings that could interfere with trial parameters including:
• History of Stevens-Johnson syndrome
• Active blepharitis or lid margin inflammation
• DED secondary to scarring, irradiation, alkali burns, cicatricial pemphigoid, or destruction of conjunctival goblet cells (as with vitamin A deficiency)

• Use of any of the following ocular therapies in the study eye within 24 hours prior to Visit 1: Vuity®, VIZZ™, topical ocular steroid treatments, topical antibiotics, prescription dry eye therapy including varenicline nasal spray, over the counter dry eye therapy (such as artificial tears, re-wetting drops, or Lumify®), TrueTear™ device (intranasal tear neurostimulator), or topical anti-glaucoma medication
• Have active uncontrolled ocular allergies or ocular allergies that are expected to be active during the trial period
• Have undergone intraocular surgery or ocular laser surgery in the study eye within 3 months prior to Visit 1; have undergone refractive surgery in the study eye within 6 months prior to Visit 1
• Have worn contact lenses within 24 hours prior to Visit 1.
• Have active ocular or systemic infection (bacterial, viral, or fungal), including fever
• Female subjects who are pregnant, nursing, or planning a pregnancy
