Eye Drops for Digital Eye Strain in Canada -- What to Use

Drops do not fix eye strain. But they help with what often comes with it.

Most of what patients call “eye strain” is two problems wearing the same costume. The focusing system fatigues from hours of sustained near work, and the tear film breaks down because blink rate drops by roughly half at a screen. Drops cannot treat the focusing part. But the dryness part is what makes a long screen day feel worse than it should – and the right drop can make a real difference.

This page sorts through the drops and ointments that are widely available in Canada and that we carry for our patients. We stock these because they cover the main categories of dry eye an optometrist actually sees – not as a comprehensive store, but as a clinical shortlist.

The daytime baseline: preservative-free aqueous tears

These are the drops to reach for during the workday. Use one consistently rather than rotating, and use it before symptoms peak rather than waiting until your eyes are already irritated.

Sodium hyaluronate (HA) drops retain water longer on the ocular surface than older formulations, which translates to fewer doses per day:

• HYLO – sodium hyaluronate 0.1%, preservative-free multi-dose bottle. The daily workhorse for many of our screen-heavy patients, and a drop we keep stocked in office.
• HYLO mini – the same formula in a smaller bottle for travel and bag use.
• I-DROP PUR – sodium hyaluronate, preservative-free multi-dose, Canadian-made.

Polymer and electrolyte aqueous drops:

• SYSTANE Hydration Preservative-Free – preservative-free unit-dose vials.
• SYSTANE Hydration Preservative-Free Multi-dose – bottle format for less waste.
• SYSTANE BION TEARS – preservative-free unit-dose with an electrolyte-balanced formulation.
• Refresh Plus – carboxymethylcellulose 0.5%, preservative-free unit-dose.
• Refresh Celluvisc – carboxymethylcellulose 1.0%, thicker formula for patients whose drops feel like they wear off quickly.
• Refresh Ophtalmique – polyvinyl alcohol 1.4%, a simpler aqueous lubricant.
• LABRELEEV Day – daytime HA drop with a paired night formulation.
• Thealoz Duo – HA plus trehalose, preservative-free multi-dose.

A note on preservatives. Once you are dosing more than four times a day, switch to preservative-free. Older drops preserved with benzalkonium chloride can irritate the ocular surface with frequent use, which is the opposite of what you want when treating dry eye. Preservative-free multi-dose bottles are more convenient than unit-dose vials and produce less waste.

Lipid-restoring drops – usually the right call for screen users

Most dry eye in long-time computer users is evaporative – the meibomian glands in the eyelids are not producing enough oil to keep the watery layer of the tear film stable. Adding more water (aqueous drops) helps temporarily; adding an oil layer addresses the actual gap.

• I-DROP MGD – lipid emulsion with HA, formulated specifically for Meibomian Gland Dysfunction.
• SYSTANE Complete – lipid-containing option that targets both aqueous and evaporative components.
• HYLO DUAL INTENSE – sodium hyaluronate plus ectoine, targets evaporative dryness and surface inflammation.

Spray rather than drops: CALMO EYE SPRAY is a liposomal spray applied to closed eyelids. It is useful for patients who cannot get drops in cleanly at their desk, contact lens wearers, and people who find drops disruptive between meetings.

Nighttime gel or ointment

If you wake up with gritty, sticky, or blurry eyes, the tear film dried out overnight. A thicker gel or ointment applied at bedtime coats the ocular surface through the night. Vision blurs briefly after application, which is why these are used at bedtime rather than during the day.

• HYLO GEL – thicker HA formulation.
• I-DROP PUR GEL – gel version of the daytime drop.
• SYSTANE Lubricant Eye Gel
• SYSTANE Ointment – petroleum-based for the heaviest overnight protection.
• Refresh Lacri-Lube – a long-established overnight ointment.
• LABRELEEV Night – paired night formulation to LABRELEEV Day.
• THEALOZ Duo Gel – HA plus trehalose in a gel base.

If bedroom humidity is below 30 percent, a humidifier paired with a night ointment makes a much bigger difference than either alone. See dry eye in winter for the Toronto-specific seasonal pattern.

What drops cannot do

Drops are lubrication. They do not change focus, correct astigmatism, treat inflammation, or unblock meibomian glands. If your screen day is leaving you with:

• Headaches during or after computer work
• Blurred vision that does not clear after looking away
• Burning that gets worse through the day even with regular drops
• Contact lens intolerance by mid-afternoon
• Symptoms that started after age 40

… then the issue is usually a combination of focusing problems, presbyopia, or structural dry eye that drops alone will not resolve. See digital eye strain and blue light glasses for the focusing side and dry eye disease for the clinical side.

When to come in

Book a structured dry eye assessment if you are dosing several times a day with limited relief, have tried more than two over-the-counter products without progress, or have fluctuating vision that clears with blinking. We assess tear film stability, meibomian gland structure (using meibography), and lid margin health to identify what is actually causing the symptoms, and match treatment to the cause.

For patients with significant Meibomian Gland Dysfunction, we offer TempSure Envi thermal radiofrequency treatment on-site.
