A team led by researchers from the University of Waterloo discovered that a significant increase in tear secretion and tear film stability after participating in aerobic exercise can be another remedy for relieving dry, itchy eyes.
Every time we blink, our eyes are covered in tear film—an essential protective coating necessary for maintaining healthy ocular function. Healthy tear film comprises three layers–oil, water, and mucin–that work together to hydrate the ocular surface and protect against infection-causing irritants like dust or dirt.
When any part of the tear film becomes unstable, the ocular surface can develop dry spots, causing eye symptoms like itchiness or stinging and burning sensations.
