Common Symptoms of Dry Eyes

Common Symptoms of Dry Eyes

Dry eye symptoms can feel different from person to person. Some people only notice mild irritation after screen use, while others feel dryness, burning, or eye fatigue throughout the day. [source]

Common dry eye symptoms may include:

• Burning or stinging eyes
• A gritty, sandy, or scratchy feeling
• Redness or general irritation
• Tired eyes, especially after long screen use
• Blurry vision that improves after blinking
• Watery eyes caused by irritation
• Mild itching or discomfort
• Sensitivity to wind, smoke, air conditioning, heating, or dry air
• A feeling that something is stuck in the eye

Watery eyes can be confusing, but they may happen when dryness irritates the eye surface. In response, the eyes may produce extra reflex tears. These tears can make the eyes water, but they may not provide steady lubrication.

If itching is the main symptom, especially with sneezing, seasonal allergies, swollen eyelids, or clear watery discharge, allergies may also be involved. In that case, a pharmacist or optometrist can help you choose whether lubricating drops, allergy drops, or another option is more suitable.

Why Do Eyes Get Dry?

Dry eyes can happen for many reasons. Common triggers include long screen time, winter heating, low humidity, air conditioning, windy weather, allergy season, smoke, air pollution, and contact lens use.

Some common causes include:

1. Screen Use and Reduced Blinking

When you focus on a computer, phone, or tablet, you may blink less often. Less blinking can affect how evenly tears spread across the eye surface. This is why many people look for eye drops for screen use, especially if their eyes feel tired or dry by the end of the workday. [source]

The CNIB recommends the 20-20-20 rule for screen users: every 20 minutes, look at something 20 feet away for 20 seconds, along with taking regular breaks from the computer.

2. Dry Air, Wind, Smoke, and Indoor Heating

Environmental conditions can make dry eyes worse. Wind, smoke, air pollution, and low humidity may all contribute to irritation.

The Canadian Association of Optometrists includes environmental conditions such as wind, air pollution, and low humidity among factors that may contribute to dry eye.

3. Aging and Hormonal Changes

Dry eye can become more common with age. Hormonal changes may also affect tear quality and tear production. This is one reason older adults may need dry eye relief products more often.

4. Contact Lens Wear

Contact lenses can make dryness more noticeable for some people. If you wear lenses, it is important to choose contact lens safe eye drops and read the product label carefully.

CNIB advises contact lens wearers to make sure the artificial tear product they use is recommended for contact lenses.

5. Medicines and Health Conditions

Some medicines and health conditions may contribute to dry eye symptoms. The Canadian Association of Optometrists notes that dry eye may be linked with general health conditions and certain medications, including antihistamines and antidepressants.

What Types of OTC Eye Drops Help Dry Eyes?

The best OTC eye drops for dry eyes depend on your symptoms, how often you need relief, whether you wear contact lenses, and whether your eyes are sensitive to preservatives.

Some drops are light enough for daytime use, while thicker gels and ointments are often better for longer-lasting or nighttime relief.

Clinical dry-eye guidance commonly lists artificial tears, lubricating drops, gels, and ointments as nonprescription options for dry-eye comfort.

A 2023 systematic review of artificial tears found good evidence that they can improve dry-eye symptoms within about one month of regular use, although improvement in clinical signs may take longer. [source]

Before using any eye drop, read the product label carefully. This is especially important if you wear contact lenses, use other eye medications, have frequent symptoms, or have sensitive eyes.

1. Artificial Tears and Lubricating Eye Drops

Artificial tears, also called lubricating eye drops, are often the first OTC option for mild dry eyes. They help add moisture to the eye surface and may reduce dryness, burning, grittiness, or tired-eye discomfort.

These drops are commonly used during the day for mild dryness caused by screen use, dry indoor air, wind, smoke, travel, or seasonal irritation. They are usually lighter than gels or ointments, so they are less likely to blur vision.

2. Preservative-Free Eye Drops

Preservative-free eye drops may be a better choice if you use drops several times a day, have sensitive eyes, or feel burning or irritation from regular formulas.

Some bottled eye drops contain preservatives to help prevent contamination after opening. For occasional use, this may not be a problem for many people.

But with frequent use, preservatives can irritate the eye surface in some users. Preservative-free drops are often packaged in single-use vials or specially designed multi-dose bottles.

3. Gel Eye Drops

Gel eye drops are thicker than regular lubricating drops. Because they stay on the eye surface longer, they may help when dryness returns quickly or feels worse later in the day.

The downside is that gel drops may temporarily blur vision. For this reason, many people prefer to use them in the evening, before bed, or at times when clear vision is not immediately needed. [source]

4. Nighttime Eye Ointments

Eye ointments are thicker than gel drops and are usually used before sleep. They can help people who wake up with dry, irritated, or gritty eyes.

Because ointments can blur vision more than regular drops, they are not usually the best choice before driving, reading, working, or using screens.

5. Contact Lens-Safe Drops

Not all dry eye drops are suitable for contact lenses. If you wear contact lenses, choose drops clearly labelled as contact lens-safe or rewetting drops.

Some drops may require you to remove your lenses before use and wait before putting them back in.

Always follow the label directions, and speak with a pharmacist or optometrist if your lenses feel dry, uncomfortable, or blurry often.

6. Drops for Screen-Related Dryness

Long screen time can make dry eye symptoms feel worse because people often blink less while focusing on screens. Light artificial tears or lubricating drops may help during work hours.

Eye drops can help with moisture, but they should not be the only step. Regular screen breaks, conscious blinking, proper lighting, and reducing direct air flow from fans or vents can also help reduce dryness and eye fatigue.

7. Drops for Burning, Itchy, or Watery Eyes

Burning, grittiness, and watery eyes can happen with dry eye. Lubricating drops may help when these symptoms are caused by dryness or irritation.

Itchy eyes need more careful attention. If itching is the main symptom, especially with sneezing, seasonal allergies, swollen eyelids, or clear watery discharge, allergies may also be involved. In that case, allergy eye drops or another option may be more suitable than standard lubricating drops.

Avoid using redness-relief drops as your main dry-eye solution unless a healthcare professional recommends them. These drops may reduce redness temporarily, but they do not treat the underlying dryness.

Best Eye Drops for Dry Eyes by Symptom

Ingredients to Look for in Dry Eye Drops

Some dry eye drops contain lubricating ingredients that help add moisture and comfort to the eye surface. The right ingredient depends on the type of dryness and the product formula.

Common ingredients may include:

Carboxymethylcellulose

Carboxymethylcellulose is commonly used in artificial tears. It helps lubricate the eye surface and may support comfort for mild to moderate dryness.

Glycerin

Glycerin helps support moisture and comfort. It is often found in lubricating eye drops for dry or irritated eyes.

Hyaluronic Acid

Hyaluronic acid helps hold moisture and may support hydration on the eye surface. It is often used in dry eye products designed for longer-lasting comfort.

Polyethylene Glycol or Propylene Glycol

These are common lubricating ingredients used in dry eye drops. They may help relieve burning, irritation, and dryness.

Mineral Oil or Petrolatum

Mineral oil or petrolatum may be found in thicker gels or ointments. These products are often used for longer-lasting or nighttime dry eye relief.

For frequent use, preservative-free options may be a better choice, especially if your eyes are sensitive.

Eye Drops to Avoid for Dry Eyes

Not all eye drops are made for dry eye relief. Some products are mainly designed to reduce redness, not to treat dryness.

Redness-relief drops may make the eyes look less red for a short time, but they may not solve the dryness problem. Some people may also experience more irritation if these drops are used too often.

For dry eyes, look for words such as:

• Artificial tears
• Lubricating eye drops
• Dry eye relief
• Preservative-free
• Contact lens-safe
• Rewetting drops, if you wear contact lenses

Avoid choosing a product only because it says “redness relief.” If you are unsure, ask a pharmacist before buying.

How Do You Choose the Best Eye Drops for Dry Eyes?

Choosing the best eye drops for dry eyes starts with understanding what your eyes need most.

If your dryness is mild or only happens sometimes, artificial tears or lubricating eye drops may be enough. If you need drops several times a day or your eyes feel easily irritated, preservative-free options may be gentler.

For dryness that feels worse at night or comes back quickly after regular drops, gel eye drops or ointments may offer longer-lasting relief. Contact lens wearers should always check the label carefully and choose only drops that are safe to use with lenses.

Here is a simple way to choose:

• Choose artificial tears for mild dryness.
• Choose lubricating drops for daily comfort and screen-related dryness.
• Choose preservative-free drops for frequent use or sensitive eyes.
• Choose gel drops for longer-lasting relief.
• Choose ointments for nighttime dryness.
• Choose contact lens-safe drops if you wear lenses.
