Best Dry Eye Drops in Australia: How to Choose

What Causes Dry Eye?

Dry eye happens when your eyes do not make enough tears, or the tears you make evaporate too quickly to keep the surface comfortable. Your tear film has three layers — an oily (lipid) layer, a watery (aqueous) layer, and a mucus layer — and a problem with any of them can leave the eye feeling dry, gritty, scratchy or tired. Confusingly, dry eye can also cause watery eyes, because irritation triggers a reflex burst of low-quality tears.

Common triggers in Australia include long hours on screens (we blink less when concentrating), air-conditioning and heating, wind and low humidity, ageing, contact lens wear, and some medicines such as antihistamines. Hormonal changes around menopause and eyelid conditions like blepharitis also contribute.

Types of Lubricating Eye Drops

Walk into any Australian pharmacy and the eye care shelf can be overwhelming. Nearly all of the products aimed at dryness are lubricating eye drops (also called artificial tears), but they differ in thickness, ingredients and packaging. Here is how the main categories differ.

Aqueous / standard lubricant drops

These are thin, watery drops that top up the tear film and wash away the gritty feeling. They are the go-to for mild, occasional dryness, they do not blur your vision, and they are the cheapest option. The trade-off is that the relief is short-lived, so you may need to reapply through the day.

Gel drops

Gel drops are thicker and cling to the eye surface for longer, so they suit more persistent dryness and give longer relief between doses. Because they are viscous, they can blur your vision briefly after instilling — many people prefer them at night or when they are not about to drive or read.

Lipid-based (oil-containing) drops

Lipid or oil-based drops add to the oily layer of the tear film, helping slow evaporation. They are designed for evaporative dry eye — the type linked to screen use, air-conditioning and meibomian gland problems — rather than simple watery topping-up.

Ointments

Eye ointments are the thickest option and are usually used at bedtime, because they blur vision significantly. They are useful if your eyes feel dry and sore on waking, which can point to eyes not fully closing overnight.

Comparing the Main Drop Types

This table summarises how the main categories of lubricating eye drops compare, so you can narrow down what is likely to suit your symptoms before you get to the pharmacy.

How to Choose Drops by Severity

A practical way to choose is to match the drop to how often and how badly your eyes bother you. Start simple and step up if you need to.

• radio_button_uncheckedOccasional or mild dryness (a few times a week): a standard aqueous lubricant drop in a multi-dose bottle is usually enough and the most economical choice.
• radio_button_uncheckedFrequent dryness (several times a day): switch to preservative-free single-use vials to avoid preservative irritation from repeated dosing.
• radio_button_uncheckedEvaporative dry eye (worse with screens, air-con or eyelid problems): try a lipid-based drop that targets the oily tear layer.
• radio_button_uncheckedDryness on waking: consider a thicker gel or an ointment at bedtime for longer overnight protection.
• radio_button_uncheckedContact lens wearers: use drops specifically labelled as suitable for use with contact lenses, ideally preservative-free.
• radio_button_uncheckedNot sure, or symptoms are persistent: ask your pharmacist, or see an optometrist who can examine the eye surface and check for underlying causes.

A Widely Available Option in Australia

Systane is one of the most commonly stocked lubricating eye drop ranges in Australian pharmacies, and the range includes standard, gel and preservative-free formats so you can match the format to your needs. Prices vary between retailers, so compare your preferred pharmacy for current pricing.

Beyond this, several other lubricant, gel and preservative-free ranges are sold across Australian pharmacies. Rather than choosing on brand alone, apply the same checklist: match the drop type to your symptoms, and choose preservative-free if you dose frequently or wear contacts.

How to Put in Eye Drops Correctly

Getting the drop onto the eye — and keeping it there — makes a difference. Wash your hands first, and check the tip of the bottle or vial has not touched anything.

• radio_button_uncheckedTilt your head back and look up towards the ceiling.
• radio_button_uncheckedGently pull down your lower eyelid to make a small pocket.
• radio_button_uncheckedSqueeze one drop into the pocket without letting the tip touch your eye, lashes or fingers, which can contaminate it.
• radio_button_uncheckedClose your eye gently for 30 seconds — try not to blink hard or squeeze, which pushes the drop out.
• radio_button_uncheckedPressing lightly on the inner corner of the eye can reduce the drop draining away too quickly.
• radio_button_uncheckedIf you need more than one type of drop, wait about five minutes between them so the first is not washed out.

Dry Eye Drops and Contact Lenses

Contact lens wear is a common cause of dry, tired eyes, but not every eye drop is safe to use while lenses are in. Some drops — particularly thicker gels and certain preservatives — can cloud lenses or build up on them. Look for drops specifically labelled as suitable for use with contact lenses (sometimes called rewetting or comfort drops), and preservative-free versions are generally the safest choice for regular use.

If your eyes are so dry that you cannot wear your lenses comfortably, raise it with your optometrist rather than simply using more drops. They can review your lens type, wearing schedule and fit, and check the health of your eye surface.

What Lubricating Drops Are Not For

It is important to know what these drops do not do. Lubricating eye drops relieve dryness and irritation — they are not a treatment for eye infections such as bacterial or viral conjunctivitis, and they do not replace antibiotic drops when those are needed. If you have a red, sticky or discharging eye, an infection or allergy may be the cause, and the right treatment is different.

Red Flags: When to See a Professional

Dry eye is usually a comfort problem, but some symptoms point to something more serious that needs proper assessment. Do not try to manage the following with lubricating drops alone.

Frequently Asked Questions

What are the best eye drops for dry eyes?

There is no single best drop for everyone, because the right choice depends on your symptoms. For occasional mild dryness, a standard aqueous lubricant drop is usually enough. If you need drops many times a day, preservative-free single-use vials are gentler on the eye surface. For eyes that dry out because tears evaporate too fast — common with screens and air-conditioning — a lipid-based drop may help more. If you are unsure, ask your pharmacist to match a product to how often and how badly your eyes bother you.

Are preservative-free eye drops better?

Not always, but they are better in specific situations. Preservatives in multi-dose bottles are fine for occasional use, but with frequent dosing they can irritate the eye surface. If you use drops more than about four to six times a day, have sensitive eyes, or wear contact lenses, preservative-free single-use vials are the better choice. For someone using drops only now and then, a standard preserved bottle is usually perfectly comfortable and more economical.

Can I use dry eye drops with contact lenses?

Only if the drops are labelled as suitable for use with contact lenses. Some drops — especially thicker gels and certain preservatives — can cloud or coat lenses. Look for drops described as suitable for contact lens wearers or as rewetting drops, and preservative-free versions are generally the safest for regular use. If your eyes are too dry to wear lenses comfortably, see your optometrist rather than just adding more drops.

How often can I use lubricating eye drops?

Standard lubricating drops can generally be used several times a day, and preservative-free drops can be used more frequently because they avoid preservative irritation. Always follow the directions on the specific product you buy. If you find you need drops very frequently to stay comfortable, that is a sign to see an optometrist or GP to look into the underlying cause rather than simply increasing how often you dose.

Why are my eyes watery if they are dry?

It sounds contradictory, but watery eyes are a common sign of dry eye. When the eye surface becomes irritated, it triggers a reflex flood of tears — but these reflex tears are watery and drain away quickly, so they do not fix the underlying dryness. Treating the dry eye itself, often with lubricating drops that stabilise the tear film, usually settles the watering. If watering is persistent or associated with other symptoms, see an optometrist or GP.

Do dry eye drops treat conjunctivitis or eye infections?

No. Lubricating eye drops relieve dryness and irritation but do not treat infections. Conjunctivitis and other eye infections often cause redness, discharge and stickiness and may need different treatment. If you have a red, sticky or discharging eye, or any pain or vision change, see a pharmacist, optometrist or GP rather than relying on lubricating drops.
