How can caffeine help in treating dry eyes?

ANSWER

Two small studies have found that caffeine seems to increase the amount of tears in your eyes.While the research is promising, the studies have been small. For now, eye doctors don’t know enough about the effects of caffeine to recommend it as a treatment. Keep in mind that caffeine can affect your health in other ways, such as causing more anxiety, higher blood pressure, and trouble sleeping. So if you don’t sip caffeinated drinks now, your dry eyes are probably not a good reason to start.
