Who can join

Age: 30 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• • Age - at least 30 years
• Good general health (defined by medication use that has not changed within the last month and the absence of medical conditions or treatments that are deemed confounding to the data as determined by the PI)
• Ability to give informed consent
• Willing to spend time for the study; approximately one hour for a screening visit and 45 minutes for a data collection visit.
• Either gender
• Any racial or ethnic origin
• tear lipid thickness ≤ 75 nm

You may not qualify if…

• Active ocular inflammation
• Use of any ocular prescription medication (such as but not limited to, glaucoma medications, anti-inflammatory eye drops and Restasis or Xiidra) used within 14 days of the screening visit or started prior to the measurement visit(s).
• Currently having punctal plugs inserted in lacrimal puncta
• Current eye disease, infection or inflammation that affects the surface of the eye such as, but not limited to moderate or greater blepharitis and ocular allergy. Clinically significant (active treatment) of blepharitis, Sjogren's disease or other systemic disease that could influence MGD, corneal, conjunctival, or eyelid abnormalities that could influence lipid layer thickness, conjunctivitis of any cause, ocular infection or systemic medication such as diuretics, SSRIs, that could influence tear secretion, or sensitivity to any of the ingredient in the eye drop being tested,
• Past eye surgery, such as, but not limited to, refractive surgery. Subjects who have had cataract removal surgery more than one year ago may be considered as potential subjects.
• Female subjects may not be pregnant or lactating. (Subject will be asked to self-report these conditions.)
• Infectious diseases (for example, hepatitis, tuberculosis) or an immuno-suppressive disease (for example, HIV). (Subjects will be asked to self-report these conditions.)
• Inability to complete the screening and examination
• Inability to provide analyzable data. For example, subjects who cannot keep their eye open during the entire measurement interval (due to early blinking) or provide a readable eye image (due to eyelid laxity) or cannot sit still for 1 minute.
