Dry eye disease is a condition that affects millions of people. It happens when your eyes either don’t make enough tears or the tears dry out too quickly. While it may sound minor, dry eyes can seriously affect how your eyes feel and how well you see. If left untreated, it can impact your daily life and make it harder to read, use a screen, or even keep your eyes open comfortably.
What Is Dry Eye?
Your eyes are protected by a thin layer of tears, known as the tear film. This layer isn’t just water, it also contains oils and mucus, which keep your eyes smooth and moist. When something interferes with the tear film either by reducing tear production or causing tears to evaporate too fast, you end up with dry eyes.
Dry eye disease is considered a chronic condition, which means it usually needs ongoing care. You may need to work closely with an ophthalmologist (eye surgeon) or an optometrist (eye doctor who checks vision and prescribes lenses or treatments) to manage it well.
Types of Dry Eye
Dry eye isn’t just one problem, there are three main types, and some people have more than one at the same time:
1. Aqueous Deficient Dry Eye
This means your eyes don’t make enough tears. The lacrimal glands (in the upper outer part of your eyes) are responsible for producing the watery part of tears. When they don’t work well, your eyes don’t get enough moisture.
2. Evaporative Dry Eye
In this type, your eyes make enough tears, but they evaporate too quickly. This is usually caused by meibomian gland dysfunction, the oil glands in your eyelids are blocked or inflamed, so they don’t produce enough oil to keep your tears from drying up.
3. Mixed Dry Eye
Many people have both problems, not enough tears and poor-quality tear film. This makes symptoms more severe and harder to treat without a full care plan.
How Common Is It?
Dry eye disease is actually very common. In the United States alone, more than 16 million people deal with it. The number is even higher across the world.
Some people are more likely to get dry eyes than others. For example, it is more common in people over the age of 50. Women, especially after menopause, also tend to experience it more often.
If you spend a lot of time looking at screens like computers or phones, you might be more at risk too. The same goes for people who wear contact lenses regularly.
Living in places with dry air, lots of dust, or wind can also increase the chances of having dry eyes.
Could Dry Eyes Be a Sign of Something Else?
Yes. Sometimes dry eyes are just a minor issue caused by lifestyle or weather. But in other cases, they can be a sign of an underlying health problem, like:
- Sjögren’s syndrome - An autoimmune condition where your body attacks moisture-producing glands, including those in your eyes and mouth.
- Thyroid eye disease - A condition linked to thyroid problems that causes inflammation in and around the eyes.
-
Blepharitis - Chronic inflammation of the eyelids that blocks the oil glands.
Diabetes - Affects nerves and blood flow, including those involved in tear production. -
Rheumatoid arthritis or lupus - Autoimmune diseases that may also trigger dry eye symptoms.
If dry eye shows up along with joint pain, fatigue, dry mouth, or frequent infections, it's important to tell your eye doctor and possibly get tested for autoimmune issues.
Symptoms of Dry Eye
Dry eye symptoms can range from mild to severe. The most common signs include:
- Burning, stinging, or itchy eyes
- Feeling like there’s sand or grit in your eye
- Blurry or changing vision
- Redness and irritation
- Trouble wearing contact lenses
- Sensitivity to light
- Excessive tearing (ironically, a sign your eyes are trying to fix the dryness)
Sometimes, dry eye makes it hard to focus or stay on screens. You may notice your eyes feel tired even after short periods of reading or computer work.
What Causes Dry Eye?
Dry eyes can happen for a few different reasons, and sometimes it's a mix of things.
As we get older, our eyes may not make as many tears. Certain health conditions and medications can also slow down tear production.
Sometimes, tears dry up too quickly. This can happen if the tiny oil glands in your eyelids are blocked or if you don’t blink as often, especially when staring at screens.
Your surroundings can also play a role. Wind, smoke, dust, and even air conditioning can make your eyes feel dry.
Hormonal changes, like during pregnancy, menopause, or while using birth control, can affect tear balance too.
Some eye surgeries, such as LASIK or cataract surgery, might lead to dry eye symptoms afterward.
Lastly, certain medications like antihistamines, antidepressants, and hormone treatments can also cause dryness as a side effect.
Who’s at Risk?
Some people are more likely to get dry eyes, especially if they:
- Are over 50 years old
- Are female
- Use screens for more than 6 hours a day
- Wear contact lenses
- Have autoimmune or thyroid disorders
- Live in low-humidity areas
- Take medications that reduce tear production
How Doctors Diagnose Dry Eye
Dry eye is diagnosed by an eye specialist after a detailed exam. Here’s how they usually figure it out:
Medical History
You’ll be asked about your symptoms, general health, medications, and any past surgeries or infections. You may also be asked if you’ve experienced dry mouth, joint pain, or fatigue signs of autoimmune conditions like Sjögren’s syndrome.
Eye Exam
Your doctor will look closely at your eye surface and eyelids using a microscope. They’ll check your tear film and blinking pattern during eye exam.
Tear Tests
There are a few tests that help confirm dry eye:
- Schirmer’s test - A paper strip is placed under your eyelid to measure how many tears your eyes make.
- Tear breakup time - A dye is placed in your eye to see how quickly tears evaporate.
- Slit-lamp exam - A close look at your eye surface to check for inflammation or damage.
Note:- Blood tests may also be done to check for autoimmune disorders.
How to Treat Dry Eye
There’s no single treatment that works for everyone. Most people need to try more than one option to find relief.
Home Remedies
- Avoid smoke, wind, and direct air blowing at your face
- Use a humidifier indoors
- Take regular screen breaks
- Blink often while using devices
- Use warm compresses to loosen blocked oil glands
- Try omega-3 supplements (ask your doctor first)
Eye Drops
- Artificial tears - These help with mild dryness. Use as often as needed.
- Ointments - Thicker, used before bed if your eyes get dry overnight.
- Prescription drops like Restasis or Xiidra - Reduce inflammation and help tear production.
- Nasal spray (Tyrvaya) - Stimulates natural tear production through your nose.
-
Serum drops - Custom eye drops made from your own blood. Used in severe cases.
Tear Duct Plugs
If tears are draining too fast, tiny punctal plugs can be inserted to keep moisture in your eyes longer. These can be temporary or long-term.
In-Office Treatments
- LipiFlow or thermal therapy - Uses heat and massage to unclog oil glands
- IPL (Intense Pulsed Light) - Light therapy that helps reduce inflammation and improve tear quality
Special Contact Lenses
- Bandage lenses - Soft lenses that protect the eye surface
- Scleral lenses - Larger lenses that hold moisture and correct vision
Note:- Your eye doctor will help you choose the right type based on your condition.
Can You Prevent Dry Eye?
You might not be able to avoid dry eye completely, but there are simple things you can do to lower your chances.
Keeping your eyelids clean is a good start. It helps prevent blockages in the tiny glands that keep your eyes moist.
Try to avoid things that make your eyes feel dry or tired, like staring at screens too long or being in dry, windy places. Taking short breaks when using your phone or computer can really help.
Drinking enough water throughout the day is also important. Staying hydrated keeps your whole body, including your eyes, in better shape.
And don’t forget regular eye checkups, especially if you have other health issues or take medication every day. Your eye doctor can help catch any problems early.
Will It Ever Go Away?
Dry eye often doesn’t go away completely, especially if it’s caused by aging or a medical condition. But with the right care plan, most people can manage it well and keep symptoms under control.
Taking Care of Yourself
Living with dry eye can be frustrating, but you're not alone. Work closely with your ophthalmologist or optometrist, follow your treatment plan, and speak up if your symptoms change or get worse. Support groups and online communities can also be helpful if your symptoms affect your quality of life.
When to Call Your Doctor
It’s a good idea to contact your eye doctor if your dry eye symptoms suddenly get worse or if you start noticing any changes in your vision.
You should also reach out if the treatment you’re using doesn’t seem to be helping.
Pay attention to any new symptoms too. Things like joint pain or a dry mouth, along with dry eyes, could be a sign of something more serious and worth getting checked out.
Conclusion
Dry eye disease is more than just a small irritation. It can affect your comfort, vision, and quality of life. The good news is that it can be managed with the right care. Whether your symptoms are mild or severe, there are treatments and lifestyle changes that can help. The key is working with an eye care professional like an ophthalmologist or optometrist, staying consistent with your treatment, and making small adjustments to your daily habits. With the right plan, your eyes can feel better and stay healthier over time.
