How to Choose the Right Artificial Tears for Dry Eyes

If you have dry, irritated, burning, or gritty eyes, artificial tears may be one of the first treatments you try. These lubricating eye drops can provide temporary relief by adding moisture to the surface of your eyes.

However, not all artificial tears are the same. Some are better suited for occasional dryness, while others may be more appropriate for people who need to use eye drops frequently. Choosing the right type can make a difference in how comfortable your eyes feel.

As an ophthalmologist, I often see patients who have been using artificial tears for months but are still experiencing dry eye symptoms. In those cases, the important question is not always, "Which eye drop should I use?" It may be, "Why are my eyes staying dry in the first place?"

What Are Artificial Tears?

Artificial tears are lubricating eye drops designed to supplement your natural tears. They can help relieve common symptoms of dry eyes, including:

• Burning or stinging
• Gritty or sandy sensations
• Eye irritation
• Mild redness
• Blurred or fluctuating vision
• Discomfort when reading or using digital screens
• Eyes that feel tired or strained

Artificial tears can be helpful when your eyes occasionally become dry from factors such as prolonged screen use, air conditioning, wind, or contact lens wear.

They can also be part of a dry eye treatment plan for people who experience more frequent symptoms.

How Do You Choose the Right Artificial Tears?

The best artificial tears for you depend on how often you experience symptoms, how frequently you need to use the drops, and what may be contributing to your dry eyes.

When choosing an artificial tear, consider the following.

1. How Frequently Do You Need Eye Drops?

If you only need artificial tears occasionally, a preserved formulation may be suitable for some people.

If you need to use artificial tears several times a day or very frequently, preservative-free artificial tears may be worth considering. Frequent exposure to preservatives can irritate the ocular surface in some patients.

If you find yourself reaching for eye drops repeatedly throughout the day, that is also something worth discussing with an eye doctor. Needing frequent lubrication may be a sign that your dry eye needs more than temporary symptom relief.

2. Preservative-Free vs. Preserved Artificial Tears

Artificial tears are available in both preservative-free and preserved formulations.

Preservatives help prevent contamination in multi-dose bottles, but some people can develop irritation when they use preserved drops frequently.

Preservative-free artificial tears are available in individual vials as well as certain multi-dose containers designed to remain sterile without traditional preservatives.

If you use artificial tears often, ask your eye doctor whether a preservative-free option would be more appropriate for you.

3. Consider the Consistency of the Drop

Artificial tears come in different formulations and viscosities. Some are relatively thin and feel more like natural tears, while thicker gels and ointments can provide longer-lasting lubrication.

Thicker products may temporarily blur your vision, so they are often more convenient at night or when you do not need clear vision immediately afterward.

There is no single artificial tear that works best for everyone. You may need to try different formulations to find one that provides comfortable, effective relief.

4. Are You a Contact Lens Wearer?

Contact lens wear can contribute to dryness and discomfort for some people. If you wear contact lenses, make sure the eye drops you choose are compatible with your lenses.

If your eyes frequently feel dry or uncomfortable while wearing contacts, don't simply continue adding more drops. An eye examination can help determine whether your lenses, wearing schedule, tear film, or another condition may be contributing to your symptoms.
