Did you know that your eyes can produce excessive tears and still suffer from dryness at the same time? It may sound contradictory, but it is completely true-and it is key to understanding why you may buy eye drops from the pharmacy without experiencing real relief. Dry eye is not always caused by a lack of tears; in many cases, it results from poor tear quality or an imbalance in the delicate oily layer of the tear film.
Dry Eye Syndrome is more complex than it appears and far more common than many people realize. In this article, we explain its causes and symptoms and guide you through the most suitable dry eye treatment and best Eye Medications options, from daily lubricating drops and nighttime gels to knowing when it is time to see an eye specialist.
What Is Dry Eye Syndrome and What Causes It?
Dry eyes are more than a minor irritation. It is a medical condition that affects the tear film covering and protecting the surface of the eye. This tear film consists of three layers:
-
An oily layer
-
A watery layer
-
A mucous layer
These layers work together to keep the eye surface moist, smooth, and clear. When the balance of any of these layers is disrupted, uncomfortable symptoms can develop.
Causes of Dry Eye Syndrome
Dry eye syndrome develops for two main reasons:
-
The eyes do not produce enough tears.
-
Tears evaporate too quickly before they can perform their protective function.
In some cases, both factors occur together, making the condition more complex and more likely to affect vision and daily comfort.
Although aging is one of the most significant risk factors, as tear-producing glands become less efficient over time, many other causes can contribute to dry eye, including:
Health and Medical Conditions
Certain autoimmune diseases, such as Sjögren’s syndrome, rheumatoid arthritis, and lupus, can damage the tear glands.
Thyroid disorders and vitamin A deficiency may also affect tear quality and production.
Women are more prone to dry eye because of hormonal changes associated with pregnancy, menopause, and oral contraceptive use.
Medications
Many medications can reduce tear production, including:
-
Antihistamines
-
Antidepressants
-
Blood pressure medications
-
Hormonal therapies
-
Certain glaucoma eye drops
Environmental and Lifestyle Factors
Spending long hours in front of screens significantly reduces blinking frequency, accelerating tear evaporation. Additional contributing factors include exposure to wind, dry air, direct air conditioning, prolonged contact lens wear, and smoking.
Some eye surgeries, such as LASIK and cataract surgery, may also cause temporary or chronic dry eye symptoms.
Meibomian Gland Dysfunction (MGD)
These tiny glands located along the eyelid margins produce the oily layer of the tear film that prevents evaporation.
When these glands become blocked (a condition known as Meibomian Gland Dysfunction (MGD)) the tear film loses its protective barrier and evaporates more quickly. This is considered the most common cause of dry eye overall.
Dry Eye Symptoms You Should Not Ignore
Dry eyes may initially seem like nothing more than temporary fatigue or mild irritation, but ignoring it can lead to more serious complications, including corneal ulcers, scarring, and partial vision loss. Every symptom deserves attention and early evaluation.
The most common complaint is the sensation of a foreign body in the eye. Many patients describe feeling as though sand or a small particle is trapped beneath the eyelid and cannot be removed. This is often accompanied by burning or stinging, especially in dry or warm environments.
Eye redness is another common symptom. While many people associate redness with fatigue or allergies, when it occurs alongside dryness, it may indicate inflammation of the eye surface.
Light sensitivity can become severe enough to make sunny days or prolonged screen use uncomfortable.
Blurred or fluctuating vision is another concerning symptom. Tears do more than moisturize the eye - they also create a smooth optical surface over the cornea that helps maintain clear vision. When this tear layer becomes unstable, vision may improve and worsen intermittently, often changing after blinking.
Stringy mucus discharge, which may appear inside the eye or at the corners of the eyelids, is a clear sign of tear film imbalance and should be medically evaluated.
Perhaps the most confusing symptom is excessive tearing despite dryness. Although it seems paradoxical, the explanation is simple: when the tear film lacks an adequate oily layer, the watery component evaporates rapidly. In response, the tear glands produce more tears as compensation. These excess tears often spill onto the cheeks without resolving the underlying problem.
Difficulty seeing at night, discomfort while driving, and an inability to comfortably wear contact lenses are signs that the condition has progressed beyond simple irritation and is beginning to affect quality of life. At this stage, consulting an eye doctor becomes essential rather than optional.
Dry Eye Treatment with Eye Drops - What Is the Difference Between the Options?
Standing in front of a pharmacy shelf filled with dozens of products for dry eye can be confusing. They are all eye drops, so what makes one better than another?
The answer lies not in the packaging but in the active ingredients. Different formulations target different aspects of dry eye. Understanding these differences can save both time and money while helping you choose the most appropriate treatment.
Lubricating eye drops generally fall into three categories:
-
Drops that replace the missing aqueous (water) layer.
-
Drops that support the lipid (oil) layer to reduce evaporation.
-
Combination drops that address both.
Most products available in pharmacies belong to one of these groups.
Common Lubricating Eye Drops Available in Pharmacies
Artelac
The Artelac range is among the most popular eye lubrication products and is available in several versions, including Artelac Splash, Artelac Complete MDO, and Artelac Rebalance.
Most formulations contain hyaluronic acid, known for its excellent ability to retain water and hydrate the eye surface.
Some versions also contain lipid components that help reduce tear evaporation and improve tear film stability.
Artelac products are particularly suitable for people experiencing dry eye related to screen use, contact lenses, or environmental factors.
Advantages:
-
Effective and natural eye hydration
-
Suitable for frequent use
-
Available in formulations for varying levels of dryness
Systane
Systane is one of the most widely used brands for dry eye management and is available in several versions, including Ultra, Hydration, Complete, and Gel Drops.
These drops form a protective layer over the eye surface, reducing irritation and helping retain moisture.
Some formulations include lipid components that benefit patients with Meibomian gland dysfunction.
Advantages:
-
Multiple options for different severities of dry eye
-
Effective in reducing burning and foreign body sensation
-
Available in daytime and nighttime formulations
Best Types by Condition:
-
Systane Ultra: Mild to moderate dry eye
-
Systane Hydration: Enhanced hydration needs
-
Systane Complete: Dry eye associated with increased tear evaporation
-
Systane Gel/Night: Severe dry eye or overnight protection
Optive
Optive eye drops contain lubricating ingredients that replenish moisture on the eye surface, along with components designed to protect corneal and conjunctival cells from the effects of dryness.
Unlike simpler formulations, Optive combines two active moisturizing agents, making it suitable for people who need more than basic lubrication but do not yet require advanced treatments.
It is commonly used by individuals experiencing eye strain from office work or prolonged digital device use.
Advantages:
-
Good hydration with cellular protection
-
Suitable for daily use
-
Helps relieve burning and stinging sensations
Hylo-Comod
Hylo-Comod contains 0.1% sodium hyaluronate and features the unique COMOD delivery system, which keeps the bottle sterile without the need for preservatives.
It is particularly popular among patients who require frequent daily use or long-term treatment.
The product is also suitable for contact lens wearers and patients recovering from refractive eye surgery.
Advantages:
-
Preservative-free
-
Suitable for frequent use
-
Effective for chronic dry eye
Limitations:
-
May not be sufficient alone in cases of very severe dry eye
Trium
Trium eye drops are used to relieve mild to moderate dry eye symptoms and help reduce the sensation of grittiness or burning caused by dust, air conditioning, or prolonged screen exposure.
They provide hydration while also offering antioxidant protection. Like many lubricating eye drops, Trium contains hyaluronic acid, but it is distinguished by the addition of Ginkgo Biloba extract.
Ginkgo Biloba is rich in antioxidants that help protect the cells on the eye surface from cumulative damage - an added benefit not typically found in standard lubricating eye drops.
Advantages:
-
Suitable for mild dry eye
-
Easy to incorporate into a daily routine
-
Often more affordable than some specialized products
Night Gel for Severe Dry Eye
While lubricating eye drops provide relief during waking hours, many people with dry eye notice that their worst symptoms occur upon waking in the morning: eyes that feel stuck together, intense burning, or blurred vision before the eyes "wake up." This happens because some people sleep with their eyes partially open, while tear production naturally decreases during the night, allowing the ocular surface to dry out without the person realizing it.
Nighttime eye gel is not a replacement for lubricating drops - it is designed to complement them, providing around-the-clock protection.
Artelac Night Time Gel
Artelac Night Time Gel is considered one of the most intensive products in the Artelac range for severe dry eye. It contains carbomer, a substance that binds water and keeps it on the eye surface for an extended period, along with triglycerides that help reduce tear evaporation.
It is specifically designed for use before bedtime, providing long-lasting overnight hydration.
Because of its thick gel consistency, it may cause temporary blurred vision immediately after application.
The tube should be used within six weeks of opening.
Advantages:
-
Deep, long-lasting hydration
-
Excellent for people who wake up with dry or sticky eyes
-
Supports nearly all layers of the tear film
Limitations:
-
Causes temporary blurred vision
-
Should not be used while wearing contact lenses
Is Night Gel Enough on Its Own?
Night gel is not intended to be a standalone treatment. Instead, it works best when combined with suitable daytime lubricating drops. The optimal approach is to use eye drops during the day and apply a nighttime gel before sleep. If symptoms persist despite this regimen, an evaluation by an eye specialist is recommended.
Do You Wear Contact Lenses? Here's What You Need to Know
Contact lens wear is a well-established risk factor for dry eye disease. Contact lenses may reduce corneal sensitivity, leading to decreased tear production. In addition, reduced blinking during activities such as reading or computer work accelerates tear evaporation. As a result, many contact lens users feel comfortable in the morning but experience increasing discomfort throughout the day.
Not all eye drops are suitable for use with contact lenses. Benzalkonium chloride (BAK), a preservative found in approximately 70% of ophthalmic formulations, is known to damage corneal and conjunctival cells and may contribute to ocular surface irritation.
For this reason, preservative-free eye drops - or products that use preservatives that break down upon contact with tears - are generally preferred.
Practical Tips for Contact Lens Wearers
The normal blinking rate is approximately 15 blinks per minute, but this can decrease by as much as half while using screens or reading. Therefore:
-
Take regular breaks from screens.
-
Practice conscious blinking throughout the day.
Preservative-free lubricating drops are safe for frequent use, whereas drops containing preservatives are generally not recommended more than four times daily due to the risk of additional irritation.
For patients with severe dry eye, specialized contact lenses known as scleral lenses may be recommended. These large rigid lenses create a protective reservoir of moisture over the eye surface and have been shown to significantly improve comfort and quality of life in people with severe ocular surface disease.
When Should Dry Eye Be Managed Under Medical Supervision?
For most individuals with mild or occasional symptoms, regular use of over-the-counter lubricating eye drops is sufficient. However, more persistent or severe symptoms may require additional treatment options.
When Should You See an Eye Doctor?
An eye examination is recommended if:
-
Dry eye symptoms persist for an extended period.
-
You experience ongoing redness, irritation, fatigue, or eye pain.
More specifically, if you find yourself using preserved eye drops more than four times per day, this is an indication that professional evaluation is needed, as excessive use may worsen symptoms rather than improve them.
Symptoms That Require Prompt Medical Attention
Seek medical care without delay if you develop:
-
Corneal ulcers
-
Corneal scarring
-
Eye infections
-
Vision problems
These complications can result from untreated chronic dry eye.
What Can an Eye Doctor Do Beyond Eye Drops?
The first step is determining the exact type of dry eye. There is no single test that definitively diagnoses dry eye disease. Instead, eye care professionals use a combination of examinations, including:
-
Slit-lamp examination
-
Schirmer test to measure tear production
-
Tear Break-Up Time (TBUT) test to assess tear film stability and evaporation
Based on the results, treatment options may include:
Treatment for Meibomian Gland Dysfunction
If blocked Meibomian glands are the underlying cause, treatment may involve:
-
Warm compresses
-
Thermal pulsation therapies designed to open and restore gland function
Tear Retention Procedures
If tears drain too quickly, small devices called punctal plugs can be inserted into the tear drainage ducts to help tears remain on the eye surface longer.
Prescription Medications
Chronic inflammation of the ocular surface may require prescription treatments such as:
-
Cyclosporine eye drops
-
Short-term corticosteroid eye drops
These medications help reduce inflammation and improve tear production.
Dry Eye May Be a Symptom of Another Condition
Dry eye can sometimes be a manifestation of systemic diseases, including:
-
Sjögren’s syndrome
-
Rheumatoid arthritis
-
Lupus
-
Thyroid disorders
In addition, commonly used medications such as antihistamines, blood pressure medications, and antidepressants may directly contribute to dry eye symptoms.
An eye doctor is uniquely qualified to connect these factors and identify the underlying cause.
Dry Eye After Eye Surgery
Both LASIK vision correction surgery and cataract surgery are known to increase the risk of dry eye symptoms.
Although postoperative dryness often improves gradually over time, persistent or worsening symptoms require close follow-up with an eye care specialist.
Final Thoughts
The journey to effective dry eye treatment can be summarized in three simple principles:
1. Identify the Cause
Is your dry eye related to screen use, dry environments, medication side effects, or Meibomian gland dysfunction? The answer determines the most appropriate treatment.
2. Choose Your Eye Drops Wisely
Not all lubricating drops are the same. Preservative-free formulations are generally safer for frequent long-term use, while some patients require products that address deficiencies in the lipid layer, not just the aqueous layer.
3. Do Not Ignore Warning Signs
Persistent blurred vision, severe eye pain, or a lack of improvement after several weeks of regular treatment are clear signs that it is time to consult an eye doctor.
Dry eye is a treatable condition, and lasting relief is possible. The key is starting with the right treatment strategy.
