Your eyes feel dry after a long day on the computer.

They burn after scrolling on your phone.

Or maybe they feel gritty, tired or slightly blurry by evening.

In situations like these, people often reach for artificial tears.

But what exactly are they—and when should you use artificial tears?

Artificial tears are lubricating eye drops designed to mimic or supplement your natural tear film. They are commonly used for mild dry-eye symptoms and are available without a prescription. The American Academy of Ophthalmology notes that artificial tears can be used to add moisture when the eyes are dry and irritated.

But not every red, painful or blurry eye should be treated with artificial tears alone.

The key is knowing when they are appropriate—and when your symptoms need proper evaluation.

What Are Artificial Tears?

Artificial tears are lubricating eye drops made to help moisturise the surface of your eyes.

Your natural tears do much more than simply make your eyes “wet.”

They help:

Keep the cornea smooth
Reduce friction when blinking
Protect the eye surface
Maintain clear vision
Wash away small irritants

When the tear film becomes unstable or evaporates too quickly, artificial tears may provide temporary relief.

When Should You Use Artificial Tears?

Artificial tears may be useful when you have mild symptoms such as:

Dryness
Burning
Grittiness
Mild irritation
Tired eyes
Temporary blur that improves after blinking
Discomfort after screen use
Mild dryness in air-conditioned environments

They are often one of the first treatments used for mild dry eye.

1. When Your Eyes Feel Dry After Screen Time

One of the most common situations is:

“My eyes feel dry after using my laptop or phone.”

When you concentrate on a screen, you often blink less frequently.

Less blinking means your tear film may evaporate faster.

Artificial tears may temporarily improve:

Dryness
Burning
Grittiness
Intermittent blur

But they should be used along with better screen habits, not as a substitute for them.

Try:

Regular screen breaks
Complete blinking
Better screen distance
Comfortable room lighting

2. When Your Eyes Feel Dry in Air Conditioning

Air conditioning can reduce humidity and make tears evaporate more quickly.

If you spend long hours in:

Offices
Cars
Flights
Air-conditioned rooms

you may notice increasing dryness by evening.

Lubricating drops can help replace some of the moisture being lost.

It may also help to avoid having the AC vent blow directly toward your face.

3. When Your Eyes Feel Gritty or Scratchy

Dry eye often creates the sensation that:

“Something is stuck in my eye.”

You may describe it as:

Sand in the eye
Scratchiness
Roughness
Grittiness

Artificial tears can reduce friction between the eyelid and eye surface.

However, if the sensation is severe, occurs suddenly or affects only one eye, make sure there is no actual foreign body or corneal injury.

4. When Your Vision Gets Temporarily Blurry

Your tear film is part of your eye’s focusing system.

If the tear layer becomes uneven, vision can temporarily become blurry.

A common pattern is:

Vision becomes blurry → you blink → it clears for a few seconds.

Artificial tears may help when this blur is caused by tear-film instability.

But persistent blurred vision should never simply be blamed on dry eye.

Your prescription, cornea, retina and other parts of the eye may need examination.

5. When Your Eyes Burn After Long Work Hours

Burning is a common dry-eye symptom.

You may notice it after:

Working on a computer
Gaming
Editing videos
Driving for long periods
Reading
Using your phone late at night

If the burning is mild and improves with lubricating drops and breaks, dry eye may be involved.

If burning is intense or accompanied by redness, discharge, severe pain or light sensitivity, get your eyes examined.

6. When Your Eyes Water Because They Are Dry

This surprises many people.

Dry eyes can actually water excessively.

When the eye surface becomes irritated, your body may produce reflex tears.

These watery tears can overflow down your cheeks but may not contain the right balance of oil and other components needed to stay on the eye surface.

Artificial tears may sometimes improve this cycle if dryness is the underlying cause.

7. When Contact Lenses Feel Dry

Some contact lens wearers notice that their lenses feel comfortable in the morning but dry or irritating by evening.

Lubricating drops may help, but not every artificial tear is suitable for use while contact lenses are in the eye.

Check the label and use products that are specifically compatible with contact lenses, or ask your eye-care professional.

Persistent contact-lens dryness may mean you need:

A different lens material
Shorter wearing time
Better tear-film management
A different replacement schedule

Preservative-Free vs Preserved Artificial Tears

This is an important distinction.

Preserved Artificial Tears

Multi-dose bottles often contain preservatives to reduce contamination after opening.

These can be convenient for occasional use.

Preservative-Free Artificial Tears

Preservative-free drops usually come in single-use or specially designed containers.

They are often preferred when artificial tears are needed frequently.

The American Academy of Ophthalmology advises preservative-free tears if you need artificial tears more than about six times per day or if you are sensitive to preservatives.

How Often Can You Use Artificial Tears?

There is no single frequency that works for everyone.

For occasional mild dryness, you may only need them once or a few times during the day.

If you need drops repeatedly throughout the day, consider preservative-free options and discuss the underlying cause with an eye doctor.

If you find yourself needing drops every hour just to stay comfortable, that is a good reason to get a proper dry-eye evaluation.

Can You Use Artificial Tears Every Day?

Many people do use lubricating artificial tears regularly.

However, daily dependence on drops does not necessarily mean the problem is fully treated.

Chronic dry eye may be caused by:

Meibomian gland dysfunction
Reduced tear production
Eyelid inflammation
Screen-related reduced blinking
Contact lenses
Medications
Environmental factors
Autoimmune conditions

Artificial tears may relieve the symptom while the underlying cause remains.

Are Artificial Tears the Same as Redness-Relief Drops?

No.

This is an important difference.

Artificial tears are primarily designed to lubricate the eye surface.

Redness-relief drops may contain medicines that temporarily shrink blood vessels to make the eye look whiter.

They are not the same thing.

If your main problem is chronic redness, hiding the redness does not address the cause.

Are Artificial Tears the Same as Antibiotic Drops?

No.

Artificial tears:

Lubricate
Moisturise
Relieve mild dryness

Antibiotic drops are medicines used for specific bacterial infections when clinically appropriate.

Artificial tears cannot treat a bacterial eye infection.

Are Artificial Tears the Same as Steroid Drops?

Definitely not.

Steroid eye drops are prescription medicines used for specific inflammatory eye conditions.

They should not be confused with simple lubricating drops.

Do not start steroid drops without professional advice.

Can Artificial Tears Treat an Eye Infection?

No.

Artificial tears may make an irritated eye feel more comfortable, but they do not treat:

Bacterial infections
Viral infections
Serious corneal infections

If you have discharge, severe redness, pain or reduced vision, do not rely only on artificial tears.

When Are Artificial Tears Not Enough?

Artificial tears may not be enough if you have:

Persistent daily symptoms
Moderate or severe dry eye
Significant meibomian gland dysfunction
Eyelid inflammation
Severe contact-lens intolerance
Autoimmune disease
Corneal surface damage

Dry-eye treatment may need to address the specific cause.

That can include additional therapies recommended after an eye examination.

Can Artificial Tears Be Harmful?

Artificial tears are generally safe when used correctly, but eye drops must be sterile.

The FDA notes that eye products bypass some of the body’s natural defenses, so contamination can create a serious infection risk.

That is why proper handling matters.

Never touch the bottle tip to:

Your eye
Eyelashes
Fingers
Clothing
Countertops

The FDA specifically recommends washing your hands before use and keeping the dropper tip away from all surfaces.

How to Use Artificial Tears Correctly

Follow these simple steps:

Wash and dry your hands.
Check the expiry date.
Tilt your head back.
Gently pull down the lower eyelid.
Hold the bottle above the eye without touching it.
Place the recommended number of drops into the lower eyelid pocket.
Close your eye gently.
Avoid rubbing immediately afterward.
Close the bottle tightly.
Store it according to the label instructions.

Usually, one properly placed drop is enough to fill the eye’s tear reservoir.

Do Not Share Artificial Tears

Even if another family member also has dry eyes, do not share bottles.

The bottle tip can become contaminated.

Eye-drop products must remain sterile because contaminated drops can cause eye infections.

Recent FDA safety warnings have highlighted that contaminated ophthalmic products can result in serious infections and even vision loss.

Should You Use an Old Bottle of Artificial Tears?

Check:

Expiry date
How long the bottle has been open
Storage instructions
Whether the bottle tip has been contaminated
Whether the liquid looks unusual

Do not use eye drops if:

The bottle is damaged
The solution looks cloudy when it should be clear
The colour has changed
You suspect contamination

What About “Natural” or Herbal Artificial Tears?

Be careful.

“Natural” does not automatically mean safe for the eye.

The FDA warns against unapproved ophthalmic products containing ingredients not appropriate for eye use and emphasizes that products used in the eye must be sterile.

Avoid putting homemade liquids, honey or unapproved remedies directly into the eye.

What If Artificial Tears Sting?

Some drops may cause brief mild stinging.

But stop using the product and seek advice if you develop:

Significant burning
Increasing redness
Pain
Discharge
Swelling
Vision changes

The FDA advises stopping eye drops and seeking medical advice if you experience pain, discharge, vision changes or unexpected discomfort.

When Should You See an Eye Doctor Instead of Just Using Artificial Tears?

Arrange an eye examination if:

You need drops every day for weeks
The drops stop helping
Your symptoms are getting worse
Your vision stays blurry
You cannot tolerate contact lenses
One eye is much worse than the other
You have significant redness
Your eyes are painful
You have light sensitivity

These symptoms may indicate that the problem is more than simple dryness.

When Should You Seek Prompt Medical Attention?

Do not simply keep adding artificial tears if you develop:

Severe eye pain
Sudden vision loss
Significant reduction in vision
Thick discharge
Severe redness
Strong light sensitivity
Eye injury
Chemical exposure
Painful red eye while wearing contact lenses

These situations may require urgent evaluation.

Do Artificial Tears Cure Dry Eye?

Not always.

Think of artificial tears as support for the tear film.

They often relieve symptoms, but whether they solve the problem depends on why your eyes are dry.

For example:

If you have reduced tear production:

Adding tears may be helpful.

If your eyelid oil glands are blocked:

Your tears may still evaporate too quickly.

If screen use is reducing your blink rate:

Drops may help, but your screen habits also need attention.

This is why persistent dry eye requires more than simply finding a stronger bottle of drops.

Which Artificial Tears Are Best?

There is no single “best” artificial tear for everyone.

Different products vary in:

Thickness
Ingredients
Preservatives
How long they remain on the eye
Contact-lens compatibility

The AAO notes that there are many artificial tear brands and that patients may need to try different options to find one that works well for them.

If your dry eye is persistent, choose drops based on professional advice rather than simply selecting the most expensive product.

The Bottom Line: When Should You Use Artificial Tears?

Artificial tears are most useful for mild dry-eye symptoms and eye-surface irritation.

They may help when your eyes feel:

Dry
Gritty
Tired
Mildly burning
Temporarily blurry
Irritated after screen use
Uncomfortable in dry environments

But artificial tears should not become a way to ignore persistent symptoms.

If you are reaching for drops constantly, ask:

“Why are my eyes dry in the first place?”

Finding that answer is often more important than simply adding another drop.

Using Artificial Tears Every Day?

If your eyes are regularly dry, burning, gritty or blurry despite using lubricating drops, a dry-eye evaluation can identify whether the problem is reduced tears, excessive evaporation, blocked oil glands, screen habits or another eye condition.
