Dry, scratchy, burning eyes can be frustrating. You may blame your computer, phone, or a long day of reading, and sometimes those things really do play a role.

But dry eyes are not always just a screen-time problem.

Your eyes depend on a healthy layer of tears to stay comfortable and to keep the surface of the eye smooth. When there are not enough tears, or when the tears evaporate too quickly or do not work properly, your eyes can start to feel dry and irritated.

The tricky part is that dry eye can have many different causes. Your environment, age, medications, contact lenses, hormones, and some health conditions can all contribute.

Understanding what may be behind your symptoms can help you take better care of your eyes and know when it is worth getting professional advice.

What Does Dry Eye Actually Feel Like?

Dry eye does not always feel exactly like dryness.

Common symptoms can include:

A burning or stinging feeling
A scratchy or gritty sensation
Redness
Sensitivity to light
Blurry vision that comes and goes
Eye fatigue
A feeling that something is in your eye
Difficulty wearing contact lenses

One symptom that surprises many people is watery eyes.

It may seem strange to have watery eyes when you have dry eye, but irritation on the surface of the eye can trigger extra tearing. Those tears may not stay on the eye long enough to provide lasting lubrication.

Occasional dryness can happen to almost anyone. Persistent or frequently recurring symptoms are a different matter and may be worth discussing with an eye care professional.

Your Tears Are More Important Than You Think

Tears do much more than appear when you cry.

A healthy tear film helps keep the surface of the eye lubricated, comfortable, and clear. If the balance of the tear film is disrupted, the eyes may become dry even if they are still producing some tears.

For some people, the problem is reduced tear production. For others, tears evaporate too quickly. In some cases, more than one factor is involved.

That is one reason dry eye does not have a single universal solution. What helps one person may not address the underlying cause for someone else.

1. Getting Older Can Change Your Tear Production

As we age, the body can become less efficient at producing tears.

The National Eye Institute notes that dry eye becomes more common with age, particularly after age 50. This does not mean that everyone will develop dry eye, but age is an important risk factor.

Other changes that come with aging can also affect the eyes, including changes to the eyelids and the glands that contribute to a healthy tear film.

If dry eye symptoms gradually become more noticeable over time, it may be tempting to simply accept them as part of getting older. But persistent discomfort is still worth mentioning during an eye exam.

2. Your Environment May Be Drying Out Your Eyes

Sometimes the problem is not your eyes alone. It is the environment around you.

Wind, smoke, dry air, and air conditioning can all make tears evaporate more quickly. Long flights and other dry environments can also leave the eyes feeling uncomfortable.

You may notice that your symptoms are worse:

In an air-conditioned office
When sitting directly in front of a fan
Outdoors on a windy day
In smoky environments
During air travel

Simple adjustments may help reduce irritation. For example, avoiding direct airflow toward your face or using a humidifier in a very dry room may make the environment more comfortable for your eyes.

Wraparound sunglasses can also help protect the eyes from wind when outdoors.

3. Some Medications Can Contribute to Dry Eye

Dry eye can sometimes be a side effect of medication.

According to the National Eye Institute and Mayo Clinic, several types of medications may contribute to dry eye symptoms. These can include some medicines used for allergies and colds, depression, high blood pressure, and other conditions.

That does not mean you should stop taking a medication if you develop dry eyes.

Instead, if you think a medication may be contributing to your symptoms, talk with the healthcare professional who prescribed it. They can help you understand whether the medication could be involved and whether any changes are appropriate.

Never stop a prescribed medication on your own because of dry eye symptoms.

4. Contact Lenses Can Sometimes Make Dryness More Noticeable

Contact lenses can be convenient, but they may also contribute to dryness for some people.

The National Eye Institute lists contact lens use as a risk factor for dry eye. Wearing lenses for long periods or when your eyes are already irritated may make discomfort more noticeable.

If your eyes regularly feel dry while wearing contacts, it may help to discuss the issue with your eye care professional. The fit of the lenses, the type of lenses, your wearing schedule, and other factors may all matter.

It is also important not to assume that discomfort is something you simply have to tolerate.

Persistent redness, pain, or worsening vision while wearing contact lenses should be taken seriously.

5. Hormonal Changes Can Affect the Eyes Too

Hormonal changes can also influence tear production.

Dry eye is more common in women, and changes associated with pregnancy and menopause can affect the tear film. During menopause, changes in hormone levels may influence the glands that help produce the oily part of tears, allowing tears to evaporate more quickly.

This does not mean that dry eye symptoms are always caused by hormones. It simply means that hormonal changes can be one piece of the picture.

If dry eye symptoms appear alongside other noticeable changes in your health, it may be useful to discuss the full picture with a healthcare professional.

6. Some Health Conditions Are Linked to Dry Eye

Dry eye can sometimes occur alongside other health conditions.

The National Eye Institute lists conditions such as diabetes, thyroid problems, and autoimmune diseases among factors that can contribute to dry eye.

One example is Sjögren's syndrome, an autoimmune condition that can affect the glands responsible for producing tears and saliva.

Having dry eyes does not mean that you have one of these conditions.

However, if symptoms are persistent, severe, or accompanied by other health concerns, an eye doctor or healthcare professional can help determine whether further evaluation is needed.

7. You May Be Blinking Less Than You Realize

Most people do not think about blinking. It happens automatically.

But when you are concentrating on something, such as reading, driving, or working on a detailed task, you may blink less often.

Less blinking means tears may not be spread evenly across the surface of the eye. Over time, this can contribute to dryness and discomfort.

Screens are one common example, but they are not the only situation where this can happen.

If your eyes tend to feel dry during focused activities, taking regular breaks and consciously blinking a few times may help. This is a simple habit, but it can make a difference when eye discomfort is related to reduced blinking.

What Can You Do About Mild Dry Eye Symptoms?

The best approach depends on what is causing the problem, but a few general habits may help reduce everyday irritation.

You might consider:

Taking regular breaks during visually demanding tasks

If you spend long periods reading, driving, or focusing on detailed work, give your eyes occasional breaks.

Paying attention to airflow

Avoid directing fans, heaters, or air conditioning straight toward your eyes when possible.

Staying away from smoke

Smoke can irritate the eyes and may worsen dry eye symptoms.

Using lubricating eye drops when appropriate

Over-the-counter artificial tears may help some people with occasional or mild dry eye symptoms. If you are unsure which type is appropriate, an eye care professional can offer guidance.

It is important to remember that drops marketed mainly to “get the red out” are not the same as lubricating drops and may not be the best choice for ongoing dryness.

Reviewing your contact lens habits

If you wear contacts and regularly experience dryness, irritation, or blurry vision, discuss your symptoms with your eye care professional.

When Should You See an Eye Doctor?

Occasional dry eyes after a long day may not be unusual.

But it is a good idea to seek professional advice if your symptoms are persistent, keep coming back, or interfere with everyday activities.

Consider scheduling an eye exam if you regularly experience:

Ongoing redness or irritation
Frequent burning or pain
Persistent blurry vision
Increasing sensitivity to light
Difficulty wearing contact lenses
Symptoms that do not improve with simple changes

Dry eye can have many causes, and an eye care professional can check your eyes and help identify what may be contributing to the problem.

The bottom line is simple: dry eyes are common, but they are not always caused by too much screen time. Your age, environment, medications, contact lenses, hormones, overall health, and everyday habits can all play a role.

Paying attention to when your symptoms occur and what seems to make them better or worse can provide useful clues. And if dryness becomes a regular part of your day, an eye exam can help you move beyond guesswork and find an approach that fits the cause.
