Problematic dry eyes are one of the most common problems reported to eye doctors. Dry eyes result from either a decrease in the amount of tear production, or the quality or composition of the tears produced.
Common causes may include advancing age, allergies, poor diet, heating/colling environmental circumstances, hormonal changes, health status such as diabetes, arthritis, lupus, thyroid dysfunction, chemotherapy or radiation treatments and acne, rosacea, contact lens use, computer use, and patients that have a history of LASIK surgery.
In addition certain medications can contribute to dry eye symptoms such as antidepressants, antihistamines, decongestants, acne treatments, diuretics and some blood pressure medications.
Common symptoms of dry eyes may include blurred or variable vision, sensitivity to light, dryness, burning, stinging, gritty or foreign body sensations. Occasionally, the dry eye patient may experience a paradoxical excess or "reflex" tearing caused by the underlying eye surface irritation.
Treatment of this condition may include artificial tears, gels and/or lubricating ointments at bedtime, daily eyelid hygiene scrub procedures, a prescribed medication regimen, omega-3 nutritional supplements (fish and flaxseed oil), and punctal (tear drainage) occlusion of the eyelid to retain moisture.
As you can see the causes and possible treatments are complex. Your eye doctor can formulate and individual treatment plan for you based on severity and known causes. Here are some helpful tips:
- Wear sunglasses outside to reduce aggravating glare and block the drying wind effect
- Stay hydrated by drinking plenty of water and fluids
- Bedroom - add a humidifier, turn off fans!
- Aim vents in cars away from your face
- Take frequent "blink breaks" when using a computer
- If taking hormone replacement therapy be sure your doctor knows about your tear problem
Use over-the-counter lubricants such as SYSTANE ULTRA Lubricant Eye drops as needed for extra relief
- Supplements such as flaxseed oil and omega-3 could provide extra benefits
- Avoid excessive caffeine
- Smoking aggravates this problem
- Environmental factors can add to your discomfort (smoke, fumes, dust)
- Airline travel can increase symptoms
- Taking antihistamines for allergy can increase symptoms
