Common Causes of Dry Eyes

When you were younger, the idea of not being able to make enough tears may have sounded almost impossible. Tears were something that simply happened, whether from emotion, allergies, laughter, or a windy day. But as we age, many people begin to notice a different kind of eye problem: burning, stinging, watering, blurred vision, or a gritty feeling that persists. These symptoms may be signs of dry eye, a common condition that can become more noticeable with age, screen use, certain medications, medical conditions, and Arizona’s dry climate.

Tears do far more than express emotion. They help keep the surface of the eye moist, comfortable, and clear. A healthy tear film includes water for moisture, oils for lubrication, mucus for even coverage, and protective components that support eye health. When the eyes do not produce enough tears, or when tears evaporate too quickly, dry eye syndrome may develop. At Southwestern Eye Center, our eye doctors can help identify the cause of dry eye symptoms and recommend treatment options to improve comfort and protect your vision.

Most common reasons for Dry Eye Syndrome

Side Effect from Medication

  • Certain antihistamines
  • Nasal decongestants
  • Tranquilizers
  • Certain blood pressure medicines
  • Parkinson’s medications
  • Birth control pills
  • Anti-depressants

Diseases

Exposure Keratitis

Exposure keratitis can occur when the eyes do not fully close, including during sleep. When the surface of the eye stays exposed, it can become dry, irritated, and uncomfortable.

Autoimmune Disorders

Aging

Particularly as it relates to menopause. Women who only take estrogen supplements during menopause are 70 percent more likely to experience dry eye, whereas those taking estrogen and progesterone have a 30 percent increased risk of facing dry eye.

Unfortunately, dry eyes cannot be cured. However, there are many ways to obtain temporary relief.

How to help dry eyes

Artificial Drops and Ointments

Available over the counter, artificial drops are the most common solution for dry eyes. If contending with a chronic eye problem, drops are necessary every day, even when symptoms aren’t present.

Humidifier

Adding more moisture to the air speeds up tear evaporation.

Hot Compresses and Massage with Baby Oil

This helps form a thicker, steadier lipid layer. Heat warms the oils in the glands, thereby improving flow. Massage helps remove oils from the glands.

Frequent Breaks

If dry eyes result from reading or watching TV, allow yourself time to close your eyes every 10 minutes or so. This helps restore moisture and gain comfort.

Close Fitting Glasses

Wearing wrap-around shades or those with side shields can help slow tear evaporation.

If you suffer from frequent dry eyes, speak with an eye doctor. It’s important to identify the cause and, if possible, pursue a more permanent solution.

Excess tearing can occur in response to dryness as the eyes try to compensate for irritation.
