What is dry eye syndrome?

Dry Eye Syndrome (DES), also known as keratoconjunctivitis sicca, is a condition that affects countless people around the world. It occurs when the eyes fail to produce sufficient tears or when the tears evaporate too quickly, leaving the surface of the eye inadequately lubricated. This imbalance in tear production can cause a range of symptoms, from mild discomfort to serious complications that impact vision and overall eye health. While many people may dismiss dry eye as a minor annoyance, it can significantly reduce quality of life, making everyday activities like reading, driving, or working on a computer challenging and uncomfortable.
At Miami Contact Lens Institute, we believe in empowering patients with knowledge about their eye health while also providing them with the care and attention that they need to be able to manage this serious condition.
The Importance of Tears for Eye Health
Tears play a critical role in maintaining the health and function of your eyes. They form a protective barrier called the tear film, which consists of three layers: an outer oily layer, a middle watery layer, and an inner mucin layer. These layers work together to keep the eyes moist, clear, and free from irritants. The oily layer prevents evaporation, the watery layer provides hydration and nutrients, and the mucin layer ensures the tear film spreads evenly across the eye’s surface.
When this intricate system is disrupted, it can lead to an unstable tear film and result in the symptoms associated with dry eye. Without adequate lubrication, the eyes can become irritated and inflamed, increasing the risk of infection and even causing damage to the cornea. Understanding the importance of tears highlights why addressing Dry Eye Syndrome is not just about comfort but also about protecting your long-term eye health.
Common Symptoms of Dry Eye Syndrome
Dry Eye Syndrome manifests in a variety of ways, and the symptoms can range from mildly bothersome to significantly disruptive. Many patients describe a gritty or sandy sensation in their eyes, as though a foreign object is present. Other common symptoms include burning or stinging sensations, redness, and increased sensitivity to light. Some individuals may experience blurred vision that worsens after prolonged focus, such as reading or working on a computer.
Another surprising symptom is watery eyes. While it may seem counterintuitive, excessive tearing can occur when the eyes try to compensate for dryness. This reflex tearing, however, does not provide the consistent lubrication needed to relieve symptoms. If you’re experiencing any of these issues, it’s important to consult an eye care professional to determine if Dry Eye Syndrome is the underlying cause.
What Causes Dry Eye Syndrome?
Dry Eye Syndrome can result from a variety of factors, many of which are interconnected. One of the most common causes is Meibomian Gland Dysfunction (MGD), where the glands in the eyelids that produce the oily layer of the tear film become blocked or fail to function properly. Without this vital oily layer, tears evaporate too quickly, leading to dryness.
Environmental conditions also play a significant role. Dry, windy, or smoky environments can accelerate tear evaporation, as can prolonged exposure to air conditioning or heating. Digital device usage has emerged as a leading contributor to dry eye in today’s world. When we focus on screens, our blink rate decreases, causing tears to evaporate more rapidly.
Certain medical conditions, such as autoimmune diseases (e.g., Sjögren’s syndrome, lupus, and rheumatoid arthritis), diabetes, and thyroid disorders, can also reduce tear production. Additionally, medications like antihistamines, decongestants, antidepressants, and hormone replacement therapy are known to exacerbate dryness.
Hormonal changes, particularly during menopause, can significantly impact tear production, making women more prone to developing dry eye. Aging is another factor, as natural tear production declines with age, making Dry Eye Syndrome more common in individuals over 50.
Who Is at Risk for Dry Eye Syndrome?
Dry Eye Syndrome can affect anyone, but certain populations are at higher risk. Older adults are particularly vulnerable due to reduced tear production with age. Women are more likely to experience dry eye, especially those who are post-menopausal or undergoing hormonal changes. Contact lens wearers are another group prone to dry eye, as lenses can disrupt the natural tear film and exacerbate symptoms.
Individuals who spend extended periods using digital devices or living in arid, windy climates are also at greater risk. Those with autoimmune conditions or taking medications that dry out the eyes should be especially vigilant about managing their eye health.
Diagnosing and Treating Dry Eye Syndrome
Proper diagnosis is the first step in effectively managing Dry Eye Syndrome. At Miami Contact Lens Institute, we use state-of-the-art diagnostic tools to assess tear quality, quantity, and gland function. These assessments allow us to identify the specific type of dry eye a patient has—whether it’s caused by insufficient tear production, excessive tear evaporation, or a combination of both.
Once diagnosed, treatment can be tailored to the individual. For mild cases, over-the-counter artificial tears can provide temporary relief by supplementing natural tear production. However, for more persistent or severe cases, more advanced treatments are often necessary.
Advanced therapies such as LipiFlow and intense pulsed light (IPL) therapy target the underlying causes of dry eye by addressing Meibomian Gland Dysfunction. These treatments not only provide relief but also help restore the glands’ natural function. For patients with more complex cases, scleral contact lenses can be an effective option. These lenses create a tear-filled reservoir over the eye, providing constant hydration and protecting the cornea.
Lifestyle Changes for Managing Dry Eye
In addition to medical treatments, making lifestyle adjustments can help alleviate dry eye symptoms. Taking regular breaks from screens, practicing the 20-20-20 rule (looking at something 20 feet away for 20 seconds every 20 minutes), and increasing humidity in your environment can make a significant difference. Wearing wraparound sunglasses outdoors can also protect your eyes from wind and sun exposure, which can exacerbate dryness.
Dietary changes, such as incorporating omega-3 fatty acids found in fish, flaxseed, and walnuts, may also improve tear production and reduce inflammation. Staying hydrated by drinking plenty of water throughout the day is another simple yet effective way to support eye health.
