Causes, Symptoms, and Treatments
Dry Eye Syndrome affects nearly 16.4 million Americans. We’re here to guide you through common causes, symptoms, and available treatments to alleviate dry eyes, as well as explain the importance of advanced diagnostic assessments we carry out like the Tear Osmolarity Test to help diagnose and manage the condition effectively.
What are Dry Eyes?
Dry Eyes occur when the eye does not produce enough tears, or the quality of tears produced is poor, so they can’t provide the moisture needed for comfort. The tear film, which consists of three layers—oil, water, and mucus—plays a crucial role in keeping the eyes hydrated and protected. If one of these layers is compromised, it can result in dryness, irritation, and discomfort. This can range from mild to severe and may affect both the quality and quantity of the tears.
Dry Eyes Causes
There are several factors that can contribute to dry eyes, including:
- Age: As we age, tear production decreases, especially in individuals over 50.
- Hormonal Changes: Women are more likely to experience dry eyes, particularly during menopause.
- Environmental Factors: Exposure to dry climates, wind, or air conditioning can lead to drier eyes.
- Health Conditions: Conditions such as blepharitis (eyelid inflammation), diabetes, rheumatoid arthritis, and autoimmune diseases like Sjögren’s syndrome are known to be associated with dry eye disease.
- Medications: Certain medications, including antihistamines, birth control, and antidepressants, can reduce tear production.
- Extended Screen Time: Staring at digital devices for prolonged periods means you blink less, causing the eyes to dry out as moisture can’t spread regularly over the eye’s surface.
Symptoms of Dry Eyes
Symptoms of dry eyes vary from person to person. Common signs include:
- Irritated or Scratchy Eyes: A feeling of discomfort or a “gritty” sensation in the eyes.
- Burning or Redness: Dry eyes can cause inflammation, leading to redness and irritation.
- Blurred Vision: Tear instability can lead to fluctuating vision quality.
- Excessive Tearing: Your eyes may water a lot, producing tears that are poor quality as part of dry eye syndrome.
- Sensitivity to Light: Dryness can lead to increased light sensitivity.
- Eye Fatigue: Extended periods of reading or screen use can exacerbate eye strain and discomfort, drying the eyes out.
If you’re experiencing any of these symptoms, it’s important to consult our eyecare experts for advice. The first course of action will be to have a comprehensive eye exam and if required, any additional specialized tests so we can accurately diagnose the severity of your dry eyes and recommend the appropriate treatment.
One of these tests is called the RPS Inflammatory Detector which looks for specific inflammatory markers in tears so we can make a note of potential treatment options for you.
The Tear Osmolarity Test: A Key Diagnostic Tool for Dry Eyes
Another cutting-edge diagnostic tool we have invested in to help with dry eye diagnosis is TearLab Osmolarity Testing. This quick and painless assessment essentially measures the saltiness (osmolarity) of your tears. The higher the osmolarity, the more likely it is that your eye surface is damaged due to dry eye disease. By using the Tear Osmolarity test, our eye doctors can evaluate the severity of your dry eyes, create a tailored treatment plan for you to manage your symptoms effectively and track treatment progress.
How the Tear Osmolarity Test Works:
The Tear Osmolarity test involves placing a small probe onto your lower eyelids to collect a tiny sample of your tears and placed in a reader to measure osmolarity. The results from TearLab Osmolarity Testing may differ for each eye, potentially indicating whether just one is suffering from dry eye syndrome, or if the severity varies in either eye.
Dry Eyes Treatment Options
While there is no permanent cure for dry eyes, treatments can help manage the condition and improve your quality of life. The treatment we recommend for you will depend on the severity and underlying causes of your dry eyes:
1. Artificial Tears
Over-the-counter artificial tears or lubricating eye drops are commonly used to treat mild dry eye symptoms, keeping your eyes hydrated to minimize discomfort. Thicker ointments or gels to use at night are also available if you tend to wake up with drier eyes each morning.
2. Lifestyle Changes
Making certain lifestyle changes can significantly improve dry eye symptoms:
- Hydration: Drink plenty of water to keep your body and eyes hydrated.
- Screen Time Management: Follow the 20-20-20 rule—take a 20-second break every 20 minutes and look at something 20 feet away to give your eyes a break from screens.
- Think Blink: Remember to blink often to ensure tears spread across your eyes frequently to keep them moist.
- Humidifier: Using a humidifier indoors can help add moisture to the air, to counter dry environments caused by air conditioning or heating.
- Warm Compresses: Try placing a warm compress on your eyes daily for 10 minutes and then gently massage your eyes to help ease any meibomian gland blockages in your eyelids that are preventing oil from being secreted for the lipid layer of your tear film.
3. Punctal Occlusion
For individuals with severe dry eyes, we may recommend punctal occlusion. This straightforward and relatively painless procedure involves inserting small punctal plugs into areas on your eyelids to prevent tear drainage, allowing your eyes to retain moisture for a longer period. This means you may not have to rely so heavily on eye drops to continuously keep your eyes lubricated. We can remove them at any time if required.
4. Medications and Vitamins
- Omega-3 Supplements: Omega-3 fatty acids have been shown to improve tear production and promote a healthy tear film. We supply Eye Promise EZ Tears vitamins to ease dry eye symptoms.
- Prescription Eye Drops: In cases of severe, chronic inflammation, we may advise using prescription eye drops such as Restasis to increase tear production and reduce inflammation.
FAQ: Dry Eye Treatment, Causes, and Diagnosis
Dry eyes can be caused by various factors, including aging, hormonal changes, health conditions like blepharitis or diabetes, medications, environmental factors, and extended screen time.
Common symptoms include irritated, sore, red or burning eyes, watery eyes, blurred vision, sensitivity to light, and eye fatigue. If you experience these symptoms, it's important to seek professional help from our dry eye specialists.
The TearLab Osmolarity Test measures the saltiness (osmolarity) of your tears. High osmolarity levels indicate dryness and inflammation on the eye surface, helping us to diagnose dry eye disease.
Treatments include artificial tears, punctal plugs, lifestyle changes, and vitamin supplements or medications like Omega-3 supplements and Restasis prescription eye drops.
To manage dry eyes caused by extended screen time, remember to follow the 20-20-20 rule, blink more often, and use a humidifier to prevent moisture loss.
