What Causes Dry Eyes?
Dry eyes can arise from a variety of factors. Some causes are temporary, while others may be long-term or chronic. Here are the most common causes:
1. Age and Gender
As we age, tear production naturally decreases. This is particularly true for women during menopause when hormonal changes can lead to a decrease in tear production. Older adults are more likely to experience dry eyes due to the aging of the tear glands.
2. Environmental Factors
Environmental factors such as dry climates, air conditioning, heating, and exposure to wind can speed up tear evaporation, leading to dry eye symptoms. Air pollution and smoke can also irritate the eyes, exacerbating the problem.
3. Digital Eye Strain
With increased screen time due to smartphones, computers, and other digital devices, many people experience “digital eye strain.” Focusing on a screen reduces the number of times you blink, which means the tears evaporate more quickly, contributing to dry eyes.
4. Health Conditions
Certain health conditions increase the risk of dry eyes, including autoimmune diseases like Sjögren’s syndrome, rheumatoid arthritis, and thyroid disorders. These conditions affect the glands that produce tears, leading to chronic dryness.
5. Medications
Some medications can contribute to dry eyes, including antihistamines, decongestants, blood pressure medications, and certain antidepressants. These medications may reduce tear production, leaving the eyes feeling dry and uncomfortable.
