Are your eyes dry and painful? Here is what you need to know about dry eye syndrome.

Do you sometimes feel a strange, dry, or itchy sensation in your eyes? Do you ever feel like something is stuck inside your eye, or does it feel like your eyes are burning? If so, you might have a common condition known as dry eye syndrome. Do not worry, as this is something many people experience. Let us talk about this condition in detail so you can understand how to take care of your eyes.

Dry eye can make your daily routine uncomfortable, especially if you spend long hours looking at screens. Fortunately, there are many ways to manage these symptoms and protect your vision. Let us explore what happens in your eyes and how you can find lasting relief.

What Is Dry Eye Syndrome?

Simply put, dry eye happens when something affects the tear film that covers your eyes. Did you know that your eyes have a tear film made of three layers to protect them and help you see clearly? When this tear film stays smooth and stable, you enjoy clear and comfortable vision. However, if something disrupts this tear film, you may experience uncomfortable symptoms like burning, itching, watering, or blurry vision.

Think of your eyes like the windshield of a car. The windshield needs to stay clean and wet so you can see the road clearly. Tears act like the windshield wiper fluid. If those tears are missing or unstable, your vision gets blurry, much like dry eye affects your sight.

Many different factors can stop your tear film from working properly. That is why doctors consider dry eye a multifactorial disease. This means the causes and risk factors are quite complex. Because of this, finding the exact cause of your symptoms can take a little time. If you have dry eye symptoms, seeing an ophthalmologist or an optometrist for proper care is very important.

What Are the Main Types of Dry Eye?

When you hear the name, you might think dry eye simply means your eyes do not make enough tears. However, that is not the whole story. There are a few main types of dry eye:

1. Aqueous Deficient Dry Eye.

This means your eyes do not produce enough tears. The lacrimal gland, located in the upper outer corner of your eye, produces these watery tears. These tears form the middle, watery layer of your tear film. Certain autoimmune conditions can cause inflammation in this gland, making it hard to produce enough watery tears.

2. Evaporative Dry Eye.

In this type, your tears evaporate too quickly. The main cause is Meibomian gland dysfunction. These are glands inside your eyelids that create the oily top layer of the tear film. If they do not work right, that oil layer becomes unstable and cannot stop the water layer from drying out. Imagine putting a layer of oil on top of water to slow down evaporation; your eye needs that oil layer to keep tears from vanishing too fast.

3. Mixed Dry Eye.

Some people have both problems at the same time. This means your eyes do not make enough tears, and your tear film is also unstable and evaporates quickly. Both issues combine to cause dry eye symptoms.

How Common Is Dry Eye?

Dry eye is a very common condition. Research shows that millions of people experience it worldwide. It occurs more often in Asia than in North America and Europe. also, women going through menopause often experience dry eye more often due to hormonal changes.

Can Dry Eye Be a Sign of Another Health Condition?

Dry eye can happen on its own, or it can occur alongside other health conditions. Sometimes, dry eye can be a sign of underlying medical issues such as:

• Sjogren's syndrome (found in about 10 percent of people with aqueous deficient dry eye).
• Diabetes (having diabetes gives you about a 50 percent higher chance of having dry eye as a complication).
• Thyroid eye disease (thyroid-related eye conditions).
• Blepharitis (inflammation along the edge of your eyelids).

What Are the Symptoms of Dry Eye?

When you have dry eye, it can feel like something is stuck in your eye and will not come out. It might feel like sand in your eye, itching, or a scratching sensation. You might also notice these other symptoms:

• A burning sensation or stinging in your eyes.
• Sensitivity to light (photophobia).
• Blurry vision or vision that changes throughout the day.
• Mucus discharge around your eyes.
• Watery eyes with tears streaming down your cheeks.

Yes, that last one sounds a bit confusing. How can your eyes water if they are dry? This is actually a common symptom of dry eye. It happens when your Meibomian glands do not make enough oil for the outer layer of your tear film. As a result, the middle water layer evaporates quickly. To respond to this irritation, your tear glands try to make more watery tears. However, these tears cannot coat your eye properly because the oil layer is missing. Therefore, those tears do not solve the real problem.

What Causes Dry Eye?

Dry eye happens when:

• Your eyes do not produce enough tears.
• Your tears evaporate too quickly.
• Both of these things happen at the same time.

Over time, many different factors can make dry eye symptoms worse or cause them to appear in the first place.

Risk Factors for Dry Eye.

Some risk factors are outside your control. For example, the risk of dry eye increases as you age. However, you can manage other risk factors by making lifestyle changes or adjusting the medicines you take.

If you have any of the following risk factors, talk with your doctor. You may be able to make changes to lower your risk of dry eye or reduce bothersome symptoms.

Environment and Lifestyle Factors:.

Weather, how long you stare at screens, wearing contact lenses, smoking, and allergies can increase your risk of dry eye. For example, sitting right in front of an air conditioner or working in a dusty environment can make your eyes dry out faster.

medicines:.

Taking certain medicines can increase your risk of dry eye. Examples include treatments for depression, allergies, high blood pressure, glaucoma, menopause, and pain relief. also, anticholinergics, oral contraceptives, and systemic retinoids can also raise your risk.

Health Conditions:.

Various neurological conditions, eye conditions, autoimmune conditions, and endocrine conditions can increase the likelihood of dry eye.

Surgeries:.

Certain eye surgeries, such as LASIK, cataract surgery, and corneal procedures, can increase your risk of dry eye.

How Is Dry Eye Diagnosed?

Doctors diagnose dry eye by reviewing your medical history, performing a complete eye exam, and using specific diagnostic tests.

Medical History.

To understand your symptoms and medical history, your doctor may ask you to fill out a questionnaire. Be prepared to share information such as:

• Your eye symptoms and how long you have had them.
• Environmental factors that make your symptoms worse.
• Other symptoms, such as dry mouth, tooth decay, mouth sores, fatigue, and joint pain.
• Your allergy history.
• Previous eye conditions.
• Other health conditions, including allergies and chronic viral infections.
• Surgeries you have undergone.
• Whether you smoke or are exposed to secondhand smoke.
• How often you wash your eyelids and what products you use.
• Any injuries to your eye area.

Eye Exam.

Your doctor will perform a complete eye exam to check your eye health and find the cause of your symptoms. During this exam, your doctor will:

• Check for signs of dry eye.
• Look for other causes of your symptoms besides dry eye.
• Check the health of your tear film (the three tear layers covering your cornea).
• Perform specialized tests.

Tests to Diagnose Dry Eye.

There is no single test for dry eye. Instead, doctors may use several tests:

• Slit lamp exam: This test checks the amount of tears your eyes produce. Your doctor shines a light into your eyes and examines your eyes and eyelids using a microscope.
• Schirmer's test: This is another method to check tear production. Your doctor places a small paper strip inside your lower eyelid for a few minutes to stimulate tear production. Then, the doctor measures how far the tears traveled along the paper strip.
• Tear breakup time (TBUT) test: This test checks how quickly your tears evaporate. Your doctor puts a special dye in your eye and uses a microscope to see how long your tear film stays stable without breaking up. They measure the time from when you last blinked to the first dry spot appearing on your cornea. A time under 10 seconds can be a sign of dry eye.

Doctors may also order other tests, such as antibody tests, to check for underlying health conditions that could cause dry eye.

How Is Dry Eye Treated?

The main goals of dry eye treatment are to:

• Relieve your symptoms and make your eyes feel comfortable.
• Help you see clearly.
• Minimize or prevent damage to your eye surface.
• Treat the underlying cause.

Many treatment options can help you. Depending on how severe your symptoms are and any underlying health conditions you have, your doctor will decide which treatments fit you best. You might need to try a few different treatments to find what works best for you.

Things You Can Do at Home and Environmental Changes.

If your symptoms are mild, your doctor may suggest starting with simple steps you can take at home. Here are some things you can try:

• Avoid environmental triggers. This means avoiding anything that makes your symptoms worse. Common triggers include cigarette smoke, air vents blowing directly on your face, strong wind, and allergens. Wearing wraparound glasses or sunglasses when you go outside can also help.
• Use a humidifier in your bedroom. Depending on where you live, indoor humidity can drop greatly during colder months when heaters run (sometimes below 25 percent). This can worsen your dry eye symptoms, and a humidifier can help restore moisture.
• Apply a warm compress to your eyes. You can buy a heat mask for your eyes at a pharmacy and place it over your closed eyes for about 10 minutes. This helps reduce symptoms and encourages your Meibomian glands to produce more oils (lipids).
• Give your eyes a break. Take frequent breaks when reading a book or using a computer. Following the 20-20-20 rule can help. This means every 20 minutes, take your eyes off the screen for 20 seconds and look at something about 20 feet away. Also, remember to blink often while reading or looking at screens to help produce tears.
• Take omega-3 fatty acid supplements. Some studies suggest these supplements support tear production and help reduce symptoms. However, talk with your doctor before taking any supplements, as they can interact with certain medicines.

Eye Drops.

Your doctor can recommend many types of eye drops. Talk with your doctor about the options that suit you best.

• Artificial tears: Artificial tears lubricate your eyes, provide relief, and temporarily ease symptoms. You can buy these over-the-counter without a prescription, but talk to your doctor before using them. Some types contain lipids, which help prevent tears from evaporating. However, artificial tears do not treat the underlying cause of dry eye.
• Ointments: If your eyes dry out while you sleep, you can use a thicker lubricant at night, such as an ointment.
• Topical cyclosporine A eye drops (Restasis®): Cyclosporine A eye drops treat inflammation in your tear glands so they produce more and better-quality tears. You use these drops twice a day in each eye. Many people notice a good improvement in symptoms after about three months. These drops might sting slightly when you first start using them, but that feeling goes away with continued use.
• Lifitegrast eye drops (Xiidra®): Lifitegrast eye drops also treat inflammation in your tear glands and are used twice a day. These drops treat both the signs and symptoms of dry eye. While it can take up to 90 days for full relief, you may notice some improvement within two weeks.
• Varenicline nasal spray (Tyrvaya®): Varenicline stimulates your trigeminal nerve directly to increase basal tear production.
• Autologous serum drops: If your dry eye is severe, your doctor may recommend autologous serum drops. These are special artificial tears made from your own blood serum. This treatment is often effective, but it can be expensive and may not be covered by your insurance.

Punctal Occlusion.

If your eyes do not produce enough tears, punctal occlusion (temporary or permanent) can help. In a pain-free procedure, a doctor places a tiny plug into the tear drainage opening (punctum) in your lower eyelid. This blockage keeps more tears trapped on the surface of your eye.

With a temporary punctal occlusion, the plug dissolves quickly. If your dry eye improves, your doctor may suggest a permanent punctal occlusion. In that case, the doctor uses a silicone plug that stays in your tear ducts as long as needed.

In-Office Procedures.

Your doctor can perform in-office procedures to help manage your dry eye. Common options include:

• Thermal pulsation therapy (LipiFlow®): This treatment helps people whose tear film is unstable due to meibomian gland dysfunction. It gently massages and warms your eyelids to help your Meibomian glands produce oil.
• Intense pulsed light (IPL) therapy: This treatment uses pulses of light to melt thick substances blocking your Meibomian glands. This helps open your glands and allows oil to flow freely.

Therapeutic Contact Lenses.

Dry eye can make the simple act of blinking very painful because your eyelid rubs against the dry, irritated surface of your eye. Therapeutic contact lenses protect and lubricate the eye surface to help with this. These lenses come in a few types:

• Soft bandage lenses: These lenses protect your eyes and help damaged areas on your cornea heal.
• Rigid scleral lenses: These lenses are larger and rest on the white part of your eye (sclera) instead of the cornea. They protect and lubricate your eyes while also correcting your vision.

Your doctor will discuss various contact lens options with you to find the best choice.

How Can You Lower Your Risk of Dry Eye?

Because dry eye has many causes, preventing it completely can be difficult. However, these steps can help lower your risk:

• Go for annual medical exams. A primary care doctor can help you monitor your overall health. If you are worried about developing dry eye, talk with your doctor. Ask if anything in your medical history or medicine list creates a risk, and find out what steps you can take to lower that risk.
• Manage underlying health conditions. Conditions like diabetes can cause dry eye. Talk with your doctor about your diabetes risk and follow their guidance to manage your blood sugar levels.
• Make lifestyle and environmental changes. You can take many steps in your daily life to lower your dry eye risk. If you use a computer daily, take frequent breaks. Avoid cigarette smoke. Add a humidifier to your bedroom and other rooms where you spend a lot of time. Also, ask a doctor for other suggestions to keep your eyes lubricated and healthy.

Does Dry Eye Go Away Completely?

Dry eye is a chronic condition. There is no complete cure, but treatments can help you manage your symptoms successfully.

You may need to try several different treatments to find what works best for you. This can feel frustrating at times, but the effort is worth it. If your current treatments do not bring relief, or if you want to discuss other options, talk with your doctor.

Self-Care and When to See a Doctor.

Living with dry eye is not easy. Many people experience stress, anxiety, and exhaustion while trying to manage their symptoms. If your condition affects your quality of life, talk with your doctor. Finding an approach that helps you manage your symptoms may take trying a few different treatments.

Remember that millions of people have dry eye. Therefore, you do not have to face this alone. Connect with online support communities and ask your doctor for recommendations. Sharing your challenges with others who understand what you are going through can make a big difference in your daily life.

Your eye doctor will tell you how often you need to come in for medical checkups. If other health conditions cause your dry eye, you may need frequent checkups with other doctors as well. Be sure to attend every medical appointment so your care team can monitor your condition and provide treatment.

Talk with your eye doctor if you notice:

• New symptoms.
• Symptoms that get worse.
• New side effects from treatments.

Dry eye affects much more than just your physical comfort. It can impact your ability to work, socialize, and enjoy life. Dry eye can also affect your emotions and mental health. You might feel lonely, but you are not alone. Connect with others who have this condition and share your experiences. Patience and persistence are necessary, but finding relief is definitely possible.

If your current treatments do not bring relief, do not hesitate to talk with your doctor. Tell them how you feel, and ask what other treatments are available to help you manage your condition and improve your quality of life.

Take-Home Message.

Dry eye is a condition that brings discomfort and can sometimes affect your vision. Many different factors contribute to it, rather than just one cause. Not making enough tears or having your tears evaporate too quickly are the main issues.

• Symptoms: Itching, burning, redness, blurred vision, a feeling that something is stuck inside, or sometimes unexpected watering.
• Causes: Aging, the environment (AC, dust, wind), certain medicines, other health conditions (like diabetes), and staring at computer screens for too long.
• Treatments: Artificial tears, specialized eye drops, warm compresses, lifestyle changes, and sometimes minor in-office procedures performed by a doctor.
• The most important thing: If you have these symptoms, be sure to see an eye doctor. They will find the exact cause and give you the right treatment. Avoid trying unverified remedies on your own.

Remember that your eyes are precious, and taking care of them is your responsibility.
