Hyabak - 10ml

What Are Hyabak Eye Drops and How Do They Help?

If your eyes feel gritty, tired, or persistently uncomfortable, you are not alone. Dry eye syndrome affects millions of people in the UK, and finding a reliable, gentle solution matters. Hyabak eye drops offer a preservative-free approach to lubricating the ocular surface, using 0.15% sodium hyaluronate — a substance your body already produces naturally. Whether your dryness is triggered by screen use, air conditioning, contact lens wear, or simply getting older, these drops are designed to provide lasting comfort without the irritation that preservatives can sometimes cause. You can explore a wider range of products in our eye care collection if you are looking for additional support.

Dry eye is more than just an inconvenience. The NHS recognises it as a common condition that can significantly affect quality of life, causing burning, redness, and even temporary blurred vision. Hyabak is available over the counter, meaning no prescription is needed, and the 10ml bottle is designed with a multi-dose preservative-free delivery system — so every drop you instil is as clean as the first.

How Does Hyabak Work to Relieve Dry Eyes?

The active ingredient in Hyabak is sodium hyaluronate, a type of hyaluronic acid. It works by mimicking the natural components of your tear film, helping to stabilise and replenish the aqueous layer that keeps your cornea hydrated and protected.

• Sodium hyaluronate is a viscoelastic polymer — it thickens slightly under pressure (like blinking) and spreads evenly across the eye surface.
• It binds water molecules, retaining moisture on the ocular surface for longer than simple saline solutions.
• The preservative-free formulation means no benzalkonium chloride (BAK) or similar agents that can damage corneal epithelial cells with repeated use.
• The unique ABAK® bottle system allows multi-dose dispensing without preservatives, keeping the solution sterile throughout its shelf life.

This combination of sustained hydration and a clean delivery system makes Hyabak particularly suitable for people who need to use eye drops frequently throughout the day.

Who Is Hyabak Suitable For?

Hyabak is appropriate for a broad range of people experiencing dry, irritated, or uncomfortable eyes. It is particularly well-suited to those who have found preserved eye drops cause additional irritation over time.

• Adults and children over 12 experiencing dry eye symptoms
• Contact lens wearers who need a compatible lubricating drop
• People who work long hours at screens and experience digital eye strain
• Those in air-conditioned or heated environments where tear evaporation is increased
• Individuals who have had laser eye surgery and are managing post-operative dryness

It is not recommended for children under 12 without medical advice. If you are pregnant or breastfeeding, speak to your pharmacist or GP before use, even though topical eye drops are generally considered low-risk.

How Does Hyabak Compare to Other Dry Eye Drops?

Is Hyabak Safe for Long-Term Use and How Should It Be Stored?

Because Hyabak eye drops are preservative-free, they are generally well-tolerated even with frequent, long-term use. The absence of preservatives reduces the risk of toxic keratopathy — a condition associated with prolonged exposure to BAK-containing drops. That said, if your symptoms persist or worsen despite regular use, it is worth speaking to your GP or an optometrist to rule out an underlying cause.

Store Hyabak below 25°C, away from direct sunlight. Once opened, the bottle should be discarded after three months, even if solution remains. Do not use the drops if the solution appears cloudy or discoloured. If you are managing other eye conditions alongside dry eye, check with your pharmacist before combining treatments.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Hyabak and What Is It Used For?

Hyabak 10ml is a sterile, preservative-free eye drop solution containing 0.15% sodium hyaluronate. It is used to relieve the symptoms of dry eye syndrome — a condition where the eyes do not produce enough tears, or where tears evaporate too quickly. Common symptoms include a gritty or burning sensation, redness, sensitivity to light, and intermittent blurred vision. The NHS notes that dry eye is particularly common in older adults, people who wear contact lenses, and those who spend extended periods looking at screens.

Hyabak acts as a tear substitute, supplementing the natural tear film to keep the surface of the eye moist and comfortable. It is suitable for use as often as needed throughout the day and is available without a prescription.

What Do You Need to Know Before Using Hyabak?

Before using Hyabak, it is important to be aware of the following contraindications and precautions:

• Do not use if you are allergic to sodium hyaluronate or any other ingredient in the formulation.
• Not recommended for children under 12 years of age without medical supervision.
• Remove soft contact lenses before instilling drops; wait at least 15 minutes before reinserting.
• Do not use if the solution appears cloudy, discoloured, or if the bottle seal is broken.
• If you have an eye infection, eye injury, or have recently had eye surgery, consult your GP or ophthalmologist before use.
• Seek medical advice if you are pregnant or breastfeeding, even though topical ocular use is generally considered low-risk.

Known drug interactions with Hyabak are not established, as sodium hyaluronate eye drops have negligible systemic absorption. However, if you are using other eye drops or eye ointments, allow at least 5–10 minutes between applications, and always apply ointments last.

• No significant interactions with systemic medicines have been identified.
• If using other topical ophthalmic preparations, space applications by at least 5 minutes.

How Should You Use Hyabak?

Using Hyabak correctly ensures you get the most benefit from each dose. The ABAK® bottle system is designed to dispense one drop at a time without contaminating the remaining solution — so there is no need to worry about sterility between uses.

1. Wash your hands thoroughly before handling the bottle.
2. Remove contact lenses if worn.
3. Tilt your head back slightly and gently pull down your lower eyelid to create a small pocket.
4. Hold the bottle above the eye and squeeze gently to release one drop into the lower eyelid pocket.
5. Close your eye gently and blink a few times to spread the solution evenly across the eye surface.
6. Repeat in the other eye if required.
7. Replace the cap securely after use.
8. Wait at least 15 minutes before reinserting contact lenses.

What Are the Possible Side Effects of Hyabak?

Hyabak is generally very well tolerated. Because it is preservative-free, it is less likely to cause the irritation associated with some other eye drop formulations. Side effects, when they do occur, are usually mild and transient. If you experience any persistent or worsening symptoms, stop use and consult a healthcare professional. You may also find it helpful to browse our allergy and hay fever range if eye symptoms are related to seasonal allergies.

Common side effects:

• Temporary blurred vision immediately after instillation (clears within a few minutes)
• Mild stinging or burning sensation upon application
• Sensation of something in the eye

Less common side effects:

• Redness of the eye
• Watering or increased tear production
• Eyelid irritation
• Allergic reaction (rare) — symptoms may include swelling, severe itching, or rash around the eye

If you experience signs of a serious allergic reaction — such as swelling of the face, difficulty breathing, or severe eye pain — stop use immediately and seek urgent medical attention.

How Should You Store Hyabak?

Correct storage helps maintain the sterility and effectiveness of Hyabak throughout its use period.

• Store below 25°C in a cool, dry place.
• Keep away from direct sunlight and heat sources.
• Do not freeze.
• Keep out of the reach and sight of children.
• Discard the bottle 3 months after first opening, even if solution remains.
• Do not use after the expiry date printed on the bottle and carton.
• Do not share the bottle with another person — this risks cross-contamination.

If you are unsure whether your drops are still safe to use, speak to your pharmacist. Proper storage is especially important for eye preparations, as contaminated drops can cause serious eye infections.
