Understanding dry eye disease is key to finding relief. Symptoms like burning, redness, or blurry vision can disrupt your daily life. Schedule an appointment with one of the top eye specialists, such as Dr. Smith at Specialty Vision, for a personalized treatment plan.
Dry eye disease occurs when our eyes do not produce enough quality tears or when the tear film is disrupted, leading to discomfort and irritation. Tears are essential for lubricating, cleansing, and protecting the surface of the eyes by providing a smooth optical layer. When the delicate balance of the tear film is disturbed, it can become a chronic challenge that affects everyday life.
When the tear film is unstable or reduced, many patients experience a variety of symptoms that can make everyday activities uncomfortable. Here’s the thing: those symptoms can range from mild annoyances to more persistent problems that interfere with your daily routine.
These symptoms might worsen in environments with air conditioning, wind, or low humidity, and especially during prolonged screen use, making proper diagnosis and treatment essential for comfort.
Understanding the causes of dry eye disease starts with a look at the tear film, which consists of three key layers. Each layer has its own function, and any disruption can lead to symptoms of dryness. Let me explain how each layer works and the factors that may compromise them.
The tear film is an elegant, multi-layered structure that not only moistens the eyes but also keeps them clear and healthy. It consists of:
Any imbalance or damage to these layers, whether individually or in combination, can result in an unstable tear film and the symptoms associated with dry eye disease.
A primary contributor to dry eye disease is the malfunctioning of glands that produce the tear film’s layers. When the lacrimal gland fails to secrete sufficient water or when the meibomian glands do not release enough oil, the tear film suffers. Inflammation of the eyelids, known as blepharitis, is a common cause that can disturb both aqueous and lipid production.
Our eye doctors pay special attention to gland evaluations during examinations since identifying any abnormal gland activity is key to determining the precise cause of the tear film disruption. In some cases, the dysfunction may also be linked to autoimmune conditions like Sjögren’s syndrome, where the body’s immune system mistakenly attacks the glands responsible for tear production.
The environment around us plays a significant role in the health of our eyes. Dry, windy, or dusty conditions can directly cause increased evaporation of the tear film. Exposure to high altitude, low humidity, or pollution can further destabilize the tear layers. Additionally, the modern reliance on digital screens often results in reduced blinking rates, which means less spreading of the essential tear components across the ocular surface.
Even contact lens wearers might experience altered tear film dynamics, as lenses can interfere with the natural distribution of tears. The disruption of the mucin layer behind a contact lens, for instance, can compromise the overall quality of the tear film, prompting the discomfort associated with dry eye disease.
Some medications have side effects that impact tear production and composition. Drugs with anticholinergic effects—such as certain antidepressants, antihistamines, and even some blood pressure medications—can reduce the eye’s ability to produce adequate tears. Beta blockers and topical treatments for other eye conditions also sometimes play a part in reducing tear secretion or affecting gland function.
These drug-induced changes to the tear film can lead to both aqueous and mucin deficiencies, further contributing to the dryness and discomfort many patients experience.
Injury to the eye or even ocular surgery can disrupt the normal patterns of tear production. Corneal nerve damage during procedures like LASIK or repositioning of the eyelids after blepharoplasty can result in decreased tear secretion by altering the neural signals that control tearing. These changes can lead to chronic dry eye symptoms if not managed properly.
Aging is another major factor affecting tear stability. As we grow older, the natural production of tears may decline, and the glands may become less efficient. In addition, age-related anatomical changes, such as alterations in eyelid structure, can exacerbate tear film instability, making it more challenging to maintain a healthy ocular surface.
Treatment for dry eye disease is tailored to address the specific causes and symptoms affecting each individual, and a comprehensive approach is often necessary. The aim is to restore a stable, healthy tear film and to protect the ocular surface from further damage.
Here’s a look at the range of treatment options available that our eye doctors consider when working with dry eye patients.
The most common first-line treatment for dry eye disease is the use of over-the-counter artificial tears. These solutions help supplement the natural tear film, providing moisture and temporary relief from dryness and irritation. For many patients, using artificial tears several times a day can be a very effective way to manage symptoms.
In addition to standard tears, longer-acting agents such as gels, ointments, or hydrophilic inserts (like LACRISERT®) may be recommended for more severe cases. These products are specially designed to stay on the eye’s surface longer, ensuring that moisture is maintained throughout the day and overnight.
When over-the-counter options are not enough, our eye doctors may prescribe medications to address underlying inflammation—a common contributor to dry eye disease. Prescription drops like cyclosporine or lifitegrast can help reduce ocular surface inflammation and enhance natural tear production.
For some patients, short-term use of topical corticosteroids can rapidly reduce inflammation, though these are typically used with caution to avoid long-term side effects. The choice of medication is based on the severity of the symptoms and the patient’s overall medical history.
For patients who do not respond to conventional treatments, several in-office procedures can help restore the tear film and alleviate symptoms. Devices that heat the meibomian glands, such as TearCare and LipiFlow, work by gently warming the glands to improve the flow of oils necessary for a stable tear film.
Intense Pulsed Light (IPL) therapy is another option that targets inflammation around the eyelids and can help improve gland function. These treatments are usually performed by our eye doctors in a controlled, clinical setting, ensuring that the cause of the flare-up is addressed effectively.

The treatment of dry eye disease isn’t only about in-office procedures—it also requires a commitment to proper home care and daily routines. Patients are encouraged to maintain proper eyelid hygiene through regular eyelid scrubs and warm compresses. These simple habits help keep the glands clear of debris and support the natural flow of the tear film.
These lifestyle modifications, combined with the appropriate use of medications or procedures, create a comprehensive strategy for managing dry eye disease on a long-term basis.
Since dry eye disease is multifactorial, it is essential that treatment be personalized. Each patient’s symptoms, contributing factors, and lifestyle considerations are reviewed carefully by our eye doctors, so that a tailored, effective treatment plan can be developed. Whether the condition stems from gland dysfunction, environmental triggers, or medication side effects, understanding the unique needs of each patient is key. A detailed evaluation of the tear film, along with an analysis of the patient’s symptoms, helps pinpoint the underlying issues. Future management may involve periodic reassessments and adjustments, ensuring the treatment remains effective over time.
Dry eye disease is common and can significantly affect comfort and vision if untreated. With causes ranging from gland dysfunction and environmental factors to medication effects and age-related changes, understanding the root cause is essential for effective treatment. A tailored approach—including artificial tears, medications, in-office procedures, and lifestyle modifications—helps manage symptoms and restore eye health.
