What Is Dry Eye? Symptoms, Causes, and Treatment

Comprehensive information for you or a loved one — including treatment options and discounts on popular medications.

Dry eye disease, or dry eye syndrome, is a medical condition that develops when your tear (lacrimal) gland doesn’t make enough tears. It can also develop if tears don’t contain enough oil, which causes them to evaporate too fast. 

The tear film covers the cornea — the clear, front part of the eye. It’s made up of water, oil, and mucus. And it provides a protective barrier for your eye. Without enough tears, you can experience eye pain. In extreme cases, this can cause eye damage and even vision loss.

What can cause dry eye disease?

There are several things that can increase your chances of developing dry eye disease. These are discussed below.

Age

Your tear glands naturally make less tears as you get older. This increases your chances of developing dry eye. Also hormone changes during menopause lower the oil content in tears, which can trigger dry eye.

Medical conditions

Certain autoimmune conditions — especially Sjögren’s syndrome and rheumatoid arthritis — can affect the tear gland and cause dry eye disease. COVID-19 infection can also cause dry eye disease.

Eye conditions

Some eye conditions also affect the tear gland. Blepharitis, or inflammation of the eyelids, is one example. Also, previous eye surgery, including LASIK surgery, can cause dry eye.

Medications

Some medications lower your tear gland’s ability to make tears, which can lead to dry eye. For example, medications to treat blood pressure, anxiety, heartburn, and allergies can cause dry eye. 

Environment

Dry and windy environments cause tears to evaporate more quickly. You’re more likely to develop dry eye disease if you live in a dry or windy climate. 

What are the symptoms of dry eye?

Dry eye can cause symptoms like:

  • Eye pain and discomfort

  • Burning sensation in one or both eyes

  • Eye redness

  • Temporary blurred vision, often with reading

  • Gritty sensation in the eye

  • Watery eyes

It may seem odd that your eyes can feel watery if you have dry eye disease. This is because your tear gland will try to relieve irritation from dry eye by making more tears. But these lower-quality tears aren’t able to completely relieve dry eye, so other symptoms don’t go away.

How is dry eye disease diagnosed?

An eye doctor (ophthalmologist) can diagnose dry eye during a complete eye exam. Your eye doctor will examine the surface of your eyes using special tools, like a slit lamp. This will allow them to see if your tears are strong enough to protect your cornea and whether your cornea has damage. 

They may also collect a tear sample using a small paper strip to see if you’re making enough tears. They may also measure the amount of oil in your tears.

Treatments for dry eye disease

There are several ways to treat dry eye. Most people need to use a combination of treatments for complete relief. 

Artificial tears

Artificial tears are the first-choice treatment for dry eye. There are many different types of artificial tear drops available over the counter (OTC). 

Some artificial tears are thicker and prevent the tear film from evaporating as quickly. If you need artificial tear drops frequently during the day, try preservative-free artificial tears. These can be safely used multiple times a day. Make sure to throw away your single-use vial within 24 hours after opening it. 

Omega-3 fatty acid supplements

There’s evidence that omega-3 supplements can improve dry-eye symptoms. Omega-3 supplements are available OTC and are safe for most people. But it’s not clear how much people need to take for best results. Your eye doctor can help you determine the right dose for you. 

Punctal plugs

These are plugs that your ophthalmologist can place in your tear ducts. They keep tears from draining, so the tears can stay on your eye longer. 

Punctual plug placement is a short medical procedure that’s done in the ophthalmologist’s office. It doesn't require anesthesia. But your eye doctor may use numbing medication on your tear ducts. Some punctual plugs dissolve on their own, so you don’t need another procedure to remove them. 

Medications for dry eye

Prescription medications can help when other treatments aren’t enough to relieve dry eye disease. Some options are described below.

Medicated eye drops 

Restasis (cyclosporine) and Xiidra (lifitegrast) are medicated eye drops that stop eye inflammation and can keep it from coming back. Miebo (perfluorohexyloctane) is a medicated eye drop that stops tears from evaporating. All three options are FDA approved to treat dry eye disease.

Prescription nasal spray

Tyrvaya (Varenicline) is a nasal spray that’s FDA approved for the treatment of dry eye. It works by increasing tear production. 

Autologous serum tears

Autologous serum tears aren’t a prescription treatment you can pick up at a retail pharmacy. These eye drops are created in a lab from a sample of your blood. Autologous serum tears can be a good option when other options haven’t worked. They can also be helpful for people who have dry eye from an autoimmune condition.

How can you prevent dry eye disease?

There are steps you can take to keep dry eye from getting worse. Some of these are discussed below.

Move your fan

The air stream from a fan evaporates tears, worsening dry eye. Always position your fans so they aren’t blowing toward your face.

Take screen breaks

Prolonged screen time can cause eye strain and dry eye. Use the 20-20-20 rule: Every 20 minutes, take a 20-second break and look at something 20 feet away.

Get a humidifier

Humidifiers increase moisture in the air, keeping tears from evaporating too quickly. This can help lessen dry eye symptoms.

Take out your contacts

Contact lenses can disrupt the tear barrier and lower the amount of oxygen reaching your cornea. Make sure you don’t sleep with your contacts in place. Your eye doctor may also recommend limiting your contact use to a set number of hours a day. 

Avoid smoke

Smoke can trigger dry eye — including cigarette and wood smoke. Avoid smoke as much as possible.

Try a warm compress

A warm compress lets more oil flow into tears so they evaporate slower. Place a warm eye mask over both eyelids for about 10 minutes a day. 

Use lid scrubs

To clean your eyelids, use baby shampoo or OTC pads like Ocusoft lid scrubs. Gently clean the base of the eyelashes on your upper and lower lid while keeping the eye closed. Try this a few times a week.

Frequently asked questions

How do you fix dry eye?

There are many treatments for dry eye disease, like artificial tears, prescription eye drops, and nasal sprays. What works well for one person might not work well for another. Over time, you might need to change your routine or add new treatment options. 

Some medical conditions can trigger or worsen dry eye. Getting treatment for these conditions can also lessen dry eye symptoms. 

Does dry eye disease get better on its own?

Dry eye disease doesn’t usually get better or go away on its own. Sometimes, you can reverse dry eye disease. 

For example, if medications are causing your symptoms, talk to a healthcare professional about switching to another option. This may improve your dry eye symptoms. Don’t stop taking prescribed medications without first talking to your healthcare team. 

Contact lenses can worsen and trigger dry eye disease. You can consider other options for treating your nearsightedness (myopia), like glasses or surgery such as PRK and LASIK.

Can dry eyes cause blindness?

Severe and untreated dry eye disease can cause permanent vision loss. Without proper treatment, dry eye can lead to other serious eye conditions. You can develop corneal abrasions and keratitis. These conditions can lead to serious eye injuries and even vision loss.
