According to an article in Primary Care Optometry News dry eye symptoms can be caused by interactions of cosmetics. Gregory S. Moore, OD pins the problem on the interaction of different product brands rather than the used of eye make-up in general. He says “There’s the possibility that different brands of make-up are interacting and causing a problem. The U.S. Food and Drug Administration only requires companies to test the brands against themselves, so you never know if what you’re using could be causing some type of chemical reaction.” Source: https://www.pconsupersite.com
Other causes of dry eye can include hormonal changes (specifically in women) and computer eye strain.
