Understanding Dry Eye Disease
What is Dry Eye Disease?
Dry eye disease happens when your eyes do not produce enough tears, or when tears do not work correctly to keep your eyes comfortably moist. Understanding the causes and effects of dry eye can help you take control of your symptoms and protect your eyes for the long term.
Tears are made up of three different layers. These layers work together to coat and protect the eyes. The oily layer helps prevent quick evaporation, the watery layer gives moisture and nutrients, and the mucus layer lets tears spread evenly across your eyeball. Problems with any layer may cause dry eye symptoms.
Dry eye disease comes in two main types. If your tear glands produce too little watery fluid, that is called aqueous-deficient dry eye. If the outer oily layer is low or poor quality, your tears may evaporate too quickly, causing evaporative dry eye. Many people have both types at once.
Dry eye usually develops slowly, starting with mild discomfort that can get worse over time. As the tear glands make fewer or lower-quality tears, symptoms like dryness, burning, and blurry vision can become more noticeable. Early treatment helps prevent the condition from progressing.
Dry eye can affect people of all ages, but it is especially common in adults over age 50 and women going through hormonal changes. People who use screens for long periods, wear contact lenses, or have certain medical conditions may also be at higher risk of dry eye disease.
Common Causes of Dry Eye Disease
Many different factors can contribute to dry eye symptoms. Knowing what can cause or worsen dry eye helps you avoid triggers and focus on the right treatments.
As we get older, our eyes naturally make fewer tears, and hormonal shifts in women, especially after menopause, can cause or worsen dry eye.
Spending time in dry, windy climates, heated or air-conditioned spaces, or places with a lot of smoke or dust can make tears evaporate faster, leading to more dryness and irritation.
Looking at screens for long periods makes us blink less often, which causes tears to dry up and eyes to feel tired or irritated.
Some medicines, such as antihistamines, antidepressants, or blood pressure medications, may decrease tear production. Health problems like diabetes, thyroid disease, or autoimmune disorders can also cause dry eye.
Long-term use of contact lenses can affect tear stability. Surgeries like LASIK or cataract removal may reduce tear production for a while or, rarely, long term.
Inflammation of the eyelids or blocked oil glands (meibomian gland dysfunction) can make it difficult for your tears to stay on the eye and protect the surface properly.
Symptoms of Dry Eye Disease
Dry eye symptoms can look different from person to person, but recognizing them early helps you get the best care from our team at ReFocus Eye Health Penndel.
Most people notice stinging, burning, scratchy, or gritty sensations in their eyes. Sometimes, it can feel like something is stuck under your eyelids or your eyes feel very tired at the end of the day.
Dry eye can cause blurry vision that gets better for a moment when you blink or use eye drops. Your vision may change during the day or during certain activities.
Ironically, eyes that are too dry may water excessively as your body tries to make up for the lack of quality moisture. These tears, however, might not help the dryness for long.
Some people notice stringy or sticky mucus in or around their eyes, especially when waking up. Eyelids may feel stuck together in the morning.
Contact lens wearers often notice dryness or discomfort, or find they cannot wear their lenses as long as they used to.
Chronic dry eye may lead to redness and a tired appearance, with small blood vessels more visible on the whites of your eyes.
How Dry Eye is Diagnosed and Treated
Accurate diagnosis is important because dry eye can have many causes and different types may require unique treatments. At ReFocus Eye Health Penndel, our ophthalmologists use advanced tools to pinpoint the source and design a personalized plan that fits your needs.
Our team will ask about your symptoms and medical history, check your vision, and use gentle tests to measure your tear quantity and quality. Sometimes imaging or special dyes are used to look at the surface and glands of your eyes.
For mild dry eye, over-the-counter artificial tears can provide fast relief. Preservative-free drops are often best for frequent use. Your doctor can recommend a brand or type that works for your eyes.
If artificial tears are not enough, our ophthalmologists might prescribe drops or other medications to reduce inflammation or boost your natural tears. Newer options, like nasal sprays, are helping more people get relief.
Certain procedures, such as inserting tiny plugs into the tear ducts to slow drainage, or using gentle heat and massage for oil gland blockages, are available. Our advanced technology allows for treatments like intense pulsed light (IPL) or gland expression, which can improve comfort for many patients.
For challenging or severe cases, treatments like autologous serum eye drops (made from your own blood), scleral lenses, or amniotic membrane therapy may be recommended by our specialists.
At-Home Care and Lifestyle Tips
Alongside professional treatment, good habits and simple changes at home can make a big difference in managing dry eye day-to-day.
Gently applying a warm, wet cloth to your closed eyelids each day can help your oil glands work better. Keeping eyelids clean with special cleansers also supports healthier eyes.
Follow the 20-20-20 rule: every 20 minutes, look at something at least 20 feet away for 20 seconds to give your eyes a break when using screens.
Using a humidifier, avoiding blowing air directly onto your face, and wearing sunglasses outdoors can all reduce tear evaporation and help protect your eyes.
Staying well-hydrated and eating foods rich in omega-3 fatty acids, such as fish or flaxseeds, may improve your tear quality over time. Talk to your doctor before making any big changes to your supplements.
