Whether you’re seeking first-line treatment for dry eyes or relief from mild eye discomfort, this article will equip you with the knowledge you need to make informed decisions about your eye health. What are artificial tears?

Definition and availability

Artificial tears are eye drops specifically designed to mimic natural tears and provide moisture and lubrication to the eyes. These drops are available without a prescription and can be purchased over the counter at pharmacies, grocery stores, and online retailers.

The accessibility of artificial tears makes them a convenient and effortless solution for dry eyes.

Purpose and use

Primarily, artificial tears serve as the first-line treatment for dry eyes, providing relief from mild eye discomfort. They work by lubricating the surface of the eye, supplementing natural tear production, and aiding in the eye’s self-cleansing process.

Additionally, artificial tears can be beneficial in various situations, such as alleviating eye dryness caused by contact lens wear, prolonged digital device use, eye surgery, or allergies.

Uses of artificial tears

Dry eye conditions

One of the most prevalent uses for artificial tears is the treatment of dry eyes. Dry eye disease (DED) occurs when the eyes don’t produce enough tears or when the quality of tears is compromised.

This can result in symptoms such as burning, stinging, itching, redness, and a sandy or gritty sensation. Artificial tears provide immediate relief by moisturizing the eyes, reducing inflammation, and improving overall ocular comfort.

With regular use, they can combat the underlying causes of dry eyes, aiding in the restoration of natural tear production.

Other eye discomfort causes

Apart from dry eye conditions, artificial tears can also be used to alleviate eye discomfort caused by various factors:

1. Contact lens wear: Wearing contact lenses can sometimes lead to dryness and irritation.

Lubricating eye drops can restore moisture and enhance comfort, allowing you to continue enjoying the benefits of wearing contact lenses. 2.

Digital device use: Extended screen time can lead to digital eye strain, characterized by symptoms like dryness, blurry vision, and eye fatigue. Artificial tears provide relief by rehydrating the eyes and reducing the resultant discomfort.

3. Eye surgery: After undergoing procedures like LASIK or cataract surgery, it is common to experience dry eye symptoms as the eyes heal.

Artificial tears can aid in the recovery process by providing the necessary lubrication and soothing the eyes. 4.

Allergies: Allergic conjunctivitis can cause itchy, red, and watery eyes. Artificial tears can help wash away allergens, offer relief from symptoms, and minimize eye irritation caused by allergies.


By understanding the definition, availability, purpose, and uses of artificial tears, you are well-equipped to manage dry eyes and seek relief from eye discomfort. Whether you’re dealing with dry eye conditions, contact lens wear, digital device use, eye surgery, or allergies, artificial tears offer a simple and effective solution.

Remember to consult an eye care professional if your symptoms persist or worsen. Take control of your eye health, embrace the comfort, and enjoy life with refreshed and revitalized eyes through the power of artificial tears.

Ingredients in Artificial Tears


Lubricants play a crucial role in artificial tears, as they provide the necessary moisture and lubrication to the eyes. The common lubricant ingredients in artificial tears are demulcents and cellulose-based substances like carboxymethyl cellulose (CMC) and hydroxypropylmethylcellulose (HPMC).

These substances have a viscous gel-like consistency that helps retain moisture on the eye’s surface, reducing dryness and discomfort. Glycerin is another lubricant commonly found in artificial tears, as it can attract and retain moisture, enhancing the lubricating effect.


In addition to lubricants, some artificial tears contain lipids, which are fats and oils that help improve tear stability and slow down evaporation.

Lipids act as emollients, providing a protective layer to the tear film, preventing tears from evaporating too quickly.

Lanolin and mineral oil are examples of lipids found in certain artificial tears. Moreover, certain artificial tears contain omega III fatty acids, which have anti-inflammatory properties and can further enhance tear quality.

Redness relievers

Artificial tears can also include ingredients that help reduce redness in the eyes caused by irritated blood vessels. These ingredients, such as naphazoline hydrochloride, tetrahydrozoline hydrochloride, and brimonidine tartrate, work by constricting blood vessels, decreasing redness, and providing temporary relief.

However, it is important to use these ingredients sparingly and as directed, as they can cause rebound redness if used excessively or for prolonged periods.

Salt concentration

The salt concentration, or tonicity, of artificial tears can vary. Hypertonic tears have a higher salt concentration compared to the natural tear film.

These tears draw water out of the eyes, temporarily reducing swelling and congestion but can also cause temporary stinging or discomfort. On the other hand, hypotonic tears have a lower salt concentration, which helps to increase hydration and provide a gentle moisturizing effect.


Preservatives are added to some artificial tears to prevent the growth of bacteria and increase the shelf life of the product. However, preservatives can cause irritation and sensitivity in some individuals.

For those with sensitive eyes or those using artificial tears frequently, preservative-free options are available. Common preservatives found in artificial tears include benzalkonium chloride, Polyquad, Purite, and sodium chlorite.

Other additives

Artificial tears may contain additional additives to enhance their effectiveness and provide benefits beyond simple lubrication. Humectants like hydroxypropyl guar and sodium hyaluronate help retain moisture and improve tear stability.

Osmoprotectants, such as natural products like autologous serum tears or homeopathic products, aim to restore the balance of tear osmolarity in dry eye conditions. These additives cater to specific needs and conditions, offering targeted relief.

How to Choose Artificial Tears

Consulting with an eye doctor

When selecting artificial tears, it is advisable to consult with an eye doctor or healthcare professional. They can assess your specific needs, determine the cause and severity of your dry eye condition, and recommend the most suitable artificial tear formulation for you.

Considerations for formula

Consider the formula that best addresses your individual circumstances. There are general-use formulas that work well for mild dry eye symptoms, while others are specifically designed for those experiencing prolonged digital device use.

Additionally, there are formulas specifically formulated for dry eye disease (DED), targeting the underlying causes of dry eyes. If you have sensitivity to preservatives, opt for preservative-free options to minimize potential irritation.

Switching brands or formulations

Sometimes, switching to a different brand or formulation of artificial tears may be necessary. If you find that your current artificial tears do not provide sufficient relief or if you experience any side effects, talk to your eye doctor about trying a different brand or formulation.

They can guide you in finding the most effective product for your specific needs.

Dosage and frequency

Proper dosing and frequency are crucial for maximizing the benefits of artificial tears. Follow the dosing instructions provided with the product.

If you are using preservative-free artificial tears, bear in mind that the vials or single-use containers should be discarded after use. Using excessive amounts of artificial tears or using them too frequently can dilute the natural tear film and potentially worsen dryness.

Applying artificial tears

To apply artificial tears effectively, follow the instructions provided with the eye drops. Begin by washing your hands thoroughly to reduce the risk of introducing any potential irritants to your eyes.

Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Squeeze the recommended number of drops into the pocket, being careful not to touch the dropper tip to your eye or any other surface.

After applying the drops, blink gently to distribute the artificial tears evenly across the eye’s surface. In conclusion, understanding the ingredients in artificial tears, considering individual needs, and utilizing proper application techniques are key to effectively managing dry eyes and finding relief from eye discomfort.

Remember, if symptoms persist or worsen despite using artificial tears, consult with your eye doctor for further guidance. With the right choice of artificial tears, you can restore and maintain optimal eye health, enjoying the world with clear, comfortable, and well-hydrated eyes.

Side Effects of Artificial Tears

Safety and Potential Side Effects

Artificial tears are generally considered safe for most individuals and have minimal side effects. However, like any other product, individual experiences may vary.

It is important to be aware of the potential side effects that can occur when using artificial tears. Common side effects may include temporary blurred vision, a slight stinging or burning sensation upon application, or increased sensitivity to light.

These side effects are usually mild and fade quickly as the eye adjusts to the drops. In rare cases, individuals may experience an allergic reaction to the ingredients in artificial tears.

Symptoms of an allergic reaction can include redness, itching, swelling, or a rash around the eyes. If you suspect an allergic reaction, discontinue use and consult with an eye doctor or healthcare professional.

Risks of


Preservatives are often added to artificial tears to prevent bacterial growth and increase the shelf life of the product. While preservatives are generally safe for most individuals, they can cause certain risks and side effects.

Some individuals may be sensitive to preservatives, resulting in eye irritation, redness, or increased dryness. Long-term use of preservative-containing artificial tears can potentially harm the delicate corneal nerves and disrupt the natural tear film, leading to further dryness and irritation.
