Tears may not be at the forefront of your health concerns, but experts say they’re actually an important part of your ocular health and hygiene. That’s because your eyes work around the clock to produce and distribute tears made of lipids, water, and mucus, which help your eyes maintain their normal functions. “Tears keep your eyes wet and smooth, and help focus light so you can see clearly,” explains the National Eye Institute, a branch of the National Institutes of Health (NIH). “They also protect your eyes from infections and irritating things, like dirt and dust.” Having dry eyes can therefore cause a whole host of eye problems, including eye infections, corneal damage, and even vision loss.

Besides general discomfort, people with dry eyes may notice redness, sensitivity to light, stringy mucus in the eyes, and a stinging or burning sensation. Additionally, some people with dry eyes feel as though something is stuck in their eyes and experience difficulty or discomfort wearing contact lenses. They may also notice changes in their vision. If you develop dry eyes, you may find yourself frequently rubbing your eyes. While this can help stimulate the flow of tears, it also increases irritation. Experts say there’s one common cause for dry eyes that you might not expect—and it could be central to your daily beauty routine: using a hair dryer. This can cause your tears to evaporate due to the intensity of heat and direct airflow, or can worsen existing symptoms from other causes.ae0fcc31ae342fd3a1346ebb1f342fcb For this reason, the Mayo Clinic suggests that you “avoid air blowing in your eyes.” This includes air flow from “hair dryers, car heaters, air conditioners, or fans,” all of which can irritate your eyes by reducing moisture.

Certain medical conditions and medications could also be behind your scratchy, uncomfortable eyes. In particular, “antihistamines, decongestants, hormone replacement therapy, antidepressants, and drugs for high blood pressure, acne, birth control and Parkinson’s disease,” have all been linked to dry eyes, Mayo Clinic experts say. Speak with your doctor if you notice symptoms without a known cause. They may recommend a range of interventions, including minimizing your exposure to irritants, getting a humidifier, or using artificial tears to reduce discomfort.
