That’s a great question. Dry eye is multicausal. Generally as we get older, cells that create our tears become less efficient. Some medications can dry the eyes, low omega-3 intake, and dehydration are also major factors. Long hours on computers and other electronic devices are making everyone at greater risk for eye dryness.
I hope this was helpful.
