Understanding Dry Eye: A Patient’s Guide
What is Dry Eye Syndrome?
Dry eye syndrome happens when your eyes do not produce enough healthy tears or when those tears do not work properly. Learning how your tear film functions is the first step toward finding the best treatment.
Your tear film is made up of three key layers that keep the surface of your eye moist and protected.
- Oily Layer: This outer layer, produced by glands in your eyelids, helps slow down tear evaporation.
- Watery Layer: Made by your lacrimal glands, this middle layer hydrates your eye and washes away dust and particles.
- Mucus Layer: The inner layer spreads the tear film evenly across your eye and helps tears stick to the surface.
Dry eye usually occurs for two reasons. Some people do not make enough tears, known as aqueous-deficient dry eye. Others make tears that dry up too quickly, which is often due to problems with the oily layer, called evaporative dry eye. Our eye doctors carefully identify the type of dry eye you have so we can recommend the most effective treatment for your needs.
Certain factors make dry eye more likely. Understanding your personal risk can help prevent symptoms from getting worse.
- Age and Hormones: Dry eye is common after age 50, and hormonal changes, especially in women, increase risk.
- Medications: Some medications, like antihistamines, blood pressure medicine, and certain antidepressants, can lower tear production.
- Medical Conditions: Diseases such as Sjögren's syndrome, rheumatoid arthritis, diabetes, and thyroid problems are linked to dry eye.
- Environment and Habits: Wind, air conditioning, and long hours at the computer or on mobile devices can worsen symptoms by causing you to blink less or lose moisture more quickly.
Recognizing Dry Eye Symptoms
Dry eye can cause a range of symptoms, from mild discomfort to problems with vision and daily activities. Recognizing these signs early helps ensure you receive the best care.
Many people notice a dry, scratchy, or burning feeling in their eyes, which often gets worse throughout the day. It may feel like there is sand or dirt in your eye, even when nothing is there.
Blurry or fluctuating vision is common, especially during tasks like reading, driving, or extended screen use. You may also notice that your eyes are sensitive to sunlight or bright indoor lighting.
It may seem surprising, but dry eyes often water more than normal. This extra tearing is your body’s way of responding to irritation, but these tears are mostly water, which does not solve the root problem.
Your eyes may feel tired or heavy, particularly at the end of the day or after focusing for long periods. Breaks and rest often bring some relief.
Dry eye can make it difficult to wear contact lenses. Lenses may feel sticky or uncomfortable, and you may need to remove them earlier than you used to. Sometimes, dry eye is the reason people stop wearing contacts altogether.
Measuring Dry Eye: The OSDI Questionnaire
Our eye doctors at ReFocus Eye Health North Wales use special tools like the Ocular Surface Disease Index (OSDI) to measure how dry eye affects your daily life. This helps guide your diagnosis and treatment plan.
The OSDI asks you questions about your symptoms, how often they occur, and whether they affect everyday activities such as reading, driving, or being outdoors in the wind. It also asks how often your symptoms are triggered by your environment.
Your results will be given as a score from 0 to 100, showing how mild or severe your dry eye is.
- 0-12: Normal (minimal symptoms, little effect on daily life)
- 13-22: Mild (symptoms during certain tasks or exposures, but manageable)
- 23-32: Moderate (discomfort more frequent, interference with work or reading)
- 33-100: Severe (constant symptoms, significant impact on daily life or vision)
Relief and Treatment Options
At ReFocus Eye Health North Wales, we offer a wide range of treatments tailored to your specific symptoms and the type of dry eye you have. Our advanced technology and patient-centered approach help ensure you receive the care that works best for you.
Making simple changes at home can often help reduce symptoms. We may suggest following the 20-20-20 rule during screen time, increasing fluids, using a humidifier, or protecting your eyes from wind with wraparound glasses.
Over-the-counter artificial tears are usually the first step. If you need them often, preservative-free drops are safest. Our team can help you choose the right products for your eyes and explain how to use them for the best results.
If non-prescription treatments are not enough, there are prescription eye drops that target inflammation – a common cause of dry eye. These include medications like cyclosporine, lifitegrast, or even a nasal spray designed to increase natural tear production.
For stubborn or severe dry eye, we offer advanced options at our North Wales clinic. These may include tiny punctal plugs to keep more tears on the eye’s surface, or in some cases, therapies that unblock oil glands and improve the tear film using gentle heat or specialized light treatments. Your eye doctor will guide you to the best solution for your needs.
Frequently Asked Questions
Our patients often ask these questions about dry eye, its symptoms, and what to expect from treatment provided at ReFocus Eye Health North Wales.
Most cases of dry eye do not lead to lasting vision loss, but severe, untreated dry eye can cause problems like corneal damage or infections. Early diagnosis and treatment help protect your long-term eye health.
Both can cause redness and watering but allergies often cause intense itching, while dry eye is more likely to create a burning, gritty feeling. Proper diagnosis ensures you get the relief you need.
Eating foods rich in omega-3 fatty acids, like salmon, walnuts, or flaxseeds, may support healthier tear production and reduce inflammation. Our eye doctors can discuss dietary tips tailored to you.
For most people, dry eye is a long-term condition that is managed rather than cured. With the right mix of treatments and home care, nearly everyone can achieve meaningful and lasting relief.
Using artificial tears with preservatives too often can sometimes make symptoms worse. Preservative-free options are gentler and safer if you use eye drops frequently.
