Are Preservative Free Eye Drops Right for You?

 

Dry, gritty, or tired eyes are something many people deal with every single day — whether from screen use, air conditioning, contact lenses, or simply getting older. Preservative free eye drops like Numark Preservative Free Moisturising Eye Drops offer a gentle, effective way to restore moisture to the ocular surface without the added chemicals that can sometimes cause sensitivity with prolonged use. At just £6.09, this is an accessible option for anyone looking to manage dry eye symptoms at home. If you're exploring a wider range of eye health products, you can browse our full eye care collection for more options.

Dry eye disease is more common than many people realise. The NHS notes that it affects millions of people in the UK, and symptoms can range from mild discomfort to significant visual disturbance. Choosing a product without preservatives is particularly important for those who need to use drops frequently throughout the day, as preservatives such as benzalkonium chloride can accumulate on the ocular surface and cause irritation over time.

 

How Do Numark Moisturising Eye Drops Work?

 

The active ingredient in these drops is sodium hyaluronate 0.1%. Sodium hyaluronate is a form of hyaluronic acid — a substance that occurs naturally in the body, including in the vitreous humour of the eye. It has a remarkable ability to attract and hold water molecules, which is why it works so well as an ocular lubricant.

  • Sodium hyaluronate forms a stable, long-lasting film over the surface of the eye
  • This film mimics the natural tear film, reducing friction between the eyelid and cornea
  • It helps stabilise the tear film, reducing the rate of evaporation
  • Because it is preservative free, it does not disrupt the delicate cells of the ocular surface with repeated use

 

Who Should Consider Using These Eye Drops?

 

These drops are suitable for a wide range of people experiencing dry or uncomfortable eyes. They are particularly well suited to those who need to use lubricating drops multiple times a day, as the absence of preservatives reduces the risk of cumulative irritation.

  • Adults and older children with dry eye symptoms caused by environmental factors (e.g. wind, central heating, air conditioning)
  • People who spend long hours looking at screens
  • Contact lens wearers who experience end-of-day dryness (remove lenses before use)
  • Those who have previously experienced sensitivity or irritation with preserved eye drops
  • Patients managing chronic dry eye disease alongside advice from their optometrist or GP

 

How Do Numark Eye Drops Compare to Preserved Alternatives?

 

Feature Numark Preservative Free Drops Standard Preserved Eye Drops
Contains preservatives No Yes (e.g. benzalkonium chloride)
Suitable for frequent daily use Yes Generally limited to 4–6 times daily
Safe with soft contact lenses Remove lenses first; reinsert after 15 mins Often not recommended with lenses
Risk of preservative-related irritation None Possible with prolonged use

 

How Should You Store These Eye Drops and Are They Clinically Suitable?

 

These drops should be stored below 25°C and kept out of direct sunlight. Once opened, they should be used within 90 days — always check the packaging for the specific discard date. Do not refrigerate. Because they are preservative free, the formulation relies on the integrity of the container to maintain sterility, so it is important not to touch the dropper tip to any surface, including your eye.

From a clinical standpoint, sodium hyaluronate-based preservative free eye drops are widely recommended by optometrists and GPs for managing dry eye disease. They are appropriate for long-term use and are generally well tolerated. If you also experience seasonal eye irritation related to allergies, you may find it helpful to explore our allergy and hay fever range alongside your eye care routine.

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.

Specifications of Numark Preservative Free Moisturising Eye Drops

 

What Are Numark Preservative Free Moisturising Eye Drops and What Are They Used For?

 

Numark Preservative Free Moisturising Eye Drops are a sterile ophthalmic solution containing sodium hyaluronate 0.1% as the active ingredient. They are 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, blurred vision, and a feeling that something is in your eye.

Dry eye is particularly common in older adults, people who wear contact lenses, and those who spend extended periods in front of screens. Environmental factors such as central heating, air conditioning, and wind can also worsen symptoms. These drops work by supplementing the natural tear film, providing immediate and sustained relief from discomfort. Because they contain no preservatives, they are especially suitable for people who need to use lubricating drops frequently throughout the day.

 

What Do You Need to Know Before Using Numark Preservative Free Eye Drops?

 

Before using these drops, 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
  • Do not use whilst wearing soft contact lenses — remove lenses before instilling drops and wait at least 15 minutes before reinserting
  • Do not use if you have an active eye infection — seek advice from your GP or optometrist first
  • Do not use if you have recently undergone eye surgery without first consulting your surgeon or ophthalmologist
  • If you experience sudden changes in vision, eye pain, or increased redness, stop use and seek medical advice promptly
  • Keep out of the reach and sight of children

Regarding drug interactions, no significant interactions with other ophthalmic preparations have been identified. However, if you are using other eye drops or eye ointments, you should:

  • Wait at least 5 minutes between instilling different eye drops
  • Apply eye ointments last if using alongside drops
  • Inform your pharmacist or GP of all eye preparations you are currently using

  1. Wash your hands thoroughly with soap and water before handling the bottle
  2. Remove soft contact lenses if you wear them
  3. Tilt your head back slightly and look upward
  4. Gently pull down your lower eyelid to create a small pocket
  5. Hold the bottle above your eye and instil one to two drops into the pocket
  6. Blink gently to spread the drops across the surface of the eye
  7. Repeat in the other eye if required
  8. Replace the cap immediately after use and do not touch the dropper tip to any surface

What Are the Possible Side Effects of Numark Preservative Free Eye Drops?

 

Side effects with preservative free eye drops are uncommon, but as with any medicine, some people may experience them. If you notice any unexpected or persistent effects, stop using the drops and speak to your pharmacist or GP.

Common side effects:

  • Temporary blurred vision immediately after instillation (usually clears within a few minutes)
  • Mild stinging or burning sensation on application

Less common side effects:

  • Mild redness of the eye
  • Watering or increased tearing shortly after use
  • Sensitivity to light (photophobia) — rare
  • Allergic reaction (rash, swelling, or worsening eye irritation) — stop use immediately and seek medical advice

If you experience any signs of a serious allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — seek emergency medical attention immediately. You can find further information on managing eye conditions and related symptoms on the NHS website.

 

How Should You Store Numark Preservative Free Moisturising Eye Drops?

  • Keep the bottle tightly closed when not in use
  • Discard the bottle 90 days after first opening, even if solution remains

Frequently Asked Questions

Where can I buy Numark Preservative Free Moisturising Eye Drops online in the UK?

You can buy Numark Preservative Free Moisturising Eye Drops directly from Cured Pharmacy online for £6.09, with no prescription required. They are classified as a General Sale List (GSL) medicine, meaning they are available over the counter. Browse our full eye care collection for a wider range of dry eye and ocular health products.

How do Numark Preservative Free Moisturising Eye Drops work in the eye?

The active ingredient, sodium hyaluronate 0.1%, is a naturally occurring polysaccharide that has a high affinity for water molecules. When instilled into the eye, it forms a stable, long-lasting lubricating film over the ocular surface that mimics the natural tear film. This reduces friction, prevents tear evaporation, and relieves the discomfort associated with dry eye syndrome.

How do I use Numark Preservative Free Moisturising Eye Drops step by step?

Wash your hands first, then tilt your head back and gently pull down your lower eyelid to create a small pocket. Instil one to two drops into the pocket, blink gently to spread the solution, and replace the cap immediately without touching the dropper tip to any surface. Repeat in the other eye if needed.

How often can I use Numark Preservative Free Moisturising Eye Drops each day?

Because these drops contain no preservatives, they can be used as frequently as needed throughout the day without the risk of preservative-related irritation that can occur with some other eye drops. Most people find that using them whenever symptoms arise — whether that is two or ten times a day — is appropriate. If you find you need them very frequently, it is worth speaking to your optometrist or GP about the underlying cause of your dry eye.

Are Numark Preservative Free Eye Drops safe to use with contact lenses?

You must remove soft contact lenses before instilling these drops and wait at least 15 minutes before reinserting them. Hard (rigid gas permeable) lenses should also be removed prior to use. Using the drops with lenses in place could affect lens comfort and may cause the lens material to absorb components of the solution.

What are the side effects of Numark Preservative Free Moisturising Eye Drops?

Side effects are uncommon but can include temporary blurred vision immediately after instillation, which usually clears within a few minutes, and mild stinging or burning on application. Less commonly, some people may notice mild redness or increased watering of the eye. If you experience persistent irritation, worsening redness, or any signs of an allergic reaction, stop use and consult your pharmacist or GP.

Who should not use Numark Preservative Free Moisturising Eye Drops?

Do not use these drops if you are allergic to sodium hyaluronate or any other ingredient listed on the packaging. They are also not recommended for use if you have an active eye infection or have recently had eye surgery without first seeking advice from your healthcare professional. Children should only use these drops under adult supervision and on the advice of a pharmacist or GP.

What happens if I accidentally use too many drops?

Using more drops than needed is unlikely to cause serious harm, as sodium hyaluronate is a well-tolerated substance. You may experience temporary blurred vision or a watery sensation, but this should resolve quickly. If you are concerned or experience any unusual symptoms after using too many drops, contact your pharmacist for advice.

How long can I use Numark Preservative Free Moisturising Eye Drops for?

These drops are suitable for long-term use in the management of chronic dry eye disease. However, the bottle must be discarded 90 days after first opening, regardless of how much solution remains, to maintain sterility. If your symptoms have not improved after a few weeks of regular use, or if they worsen at any point, consult your GP or optometrist for further assessment.

What are the alternatives to Numark Preservative Free Moisturising Eye Drops?

There are several other preservative free eye drops available in the UK, including those containing hypromellose, carbomer, or carmellose sodium as the active lubricant. The best choice depends on the severity of your dry eye and personal preference — some people prefer a thicker gel-type drop for overnight use, while others prefer a lighter solution for daytime use. Your pharmacist or optometrist can help you choose the most appropriate option from our eye care range.

Can I use Numark Preservative Free Eye Drops if I have glaucoma?

If you have glaucoma, you are likely already using prescribed eye drops to manage your intraocular pressure. You can generally use lubricating drops alongside glaucoma medication, but you should wait at least five minutes between instilling different eye preparations. Always inform your ophthalmologist or GP that you are using additional eye drops so they can advise accordingly.

Are Numark Preservative Free Moisturising Eye Drops suitable during pregnancy or breastfeeding?

Sodium hyaluronate is considered to have a low systemic absorption when applied to the eye, and there is no evidence of harm during pregnancy or breastfeeding at the concentrations used in eye drops. However, as with any medicine, it is advisable to consult your GP or midwife before using these drops if you are pregnant or breastfeeding, to ensure they are appropriate for your individual circumstances.

Can dry eyes be a sign of something more serious?

In most cases, dry eye is a benign and manageable condition, but it can occasionally be associated with underlying conditions such as Sjögren's syndrome, rheumatoid arthritis, or thyroid disease. If your dry eye symptoms are severe, persistent, or accompanied by other symptoms such as joint pain or a dry mouth, it is worth discussing this with your GP. Sudden changes in vision or significant eye pain should always be assessed promptly by a healthcare professional.

Do Numark Preservative Free Eye Drops interact with any other medicines?

No significant interactions between sodium hyaluronate eye drops and other medicines have been identified. If you are using other eye drops or ointments, wait at least five minutes between applications and apply ointments last. Always let your pharmacist know about all medicines you are currently using, including other eye preparations, to ensure there are no concerns specific to your situation.

What is the latest research on sodium hyaluronate eye drops for dry eye?

Sodium hyaluronate has been extensively studied as an ocular lubricant and is well established in clinical practice for the management of dry eye disease. Research consistently supports its effectiveness in improving tear film stability, reducing ocular surface damage, and relieving subjective symptoms of dryness. It is widely recommended by optometrists and ophthalmologists in the UK as a first-line lubricant, particularly in preservative free formulations for patients requiring frequent dosing. If you are also managing allergy-related eye symptoms, our allergy and hay fever range may offer additional support.

How Should You Use Numark Preservative Free Moisturising Eye Drops?

Using these drops correctly is straightforward, but a few simple steps make a real difference to both comfort and safety. Always wash your hands before handling the bottle, and never allow the dropper tip to touch your eye, eyelid, or any other surface, as this can introduce bacteria and compromise the sterility of the solution.

Follow these steps each time you use the drops:

What Is the Correct Dose of Numark Preservative Free Moisturising Eye Drops?

The standard dose is one to two drops instilled into the affected eye or eyes as needed. Because these drops are preservative free, there is no strict upper limit on daily frequency — you can use them whenever your eyes feel dry or uncomfortable. That said, if you find yourself needing them very frequently, it is worth discussing this with your pharmacist or optometrist to ensure you are managing the underlying cause of your dry eye effectively.

When Is the Best Time to Use Numark Preservative Free Moisturising Eye Drops?

There is no fixed time of day for using these drops — you should use them whenever your eyes feel dry, gritty, or uncomfortable. Many people find they need them most during prolonged screen use, in air-conditioned or heated environments, or when outdoors in windy conditions. Some people also benefit from using a drop first thing in the morning if their eyes feel dry on waking, and again in the evening before bed.

If you are using other prescribed eye drops, wait at least five minutes between applications to allow each preparation to be absorbed properly before instilling the next.

How Long Can You Use Numark Preservative Free Moisturising Eye Drops For?

These drops are suitable for ongoing, long-term use in the management of dry eye disease. There is no recommended maximum duration of treatment. However, you must discard the bottle 90 days after first opening, even if solution remains, to ensure sterility is maintained. Always check the expiry date on the packaging before use.

If your symptoms have not improved after several weeks of regular use, or if they worsen at any point, stop using the drops and consult your GP or optometrist. Persistent or worsening dry eye may require further investigation or a different treatment approach.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Numark Preservative Free Moisturising Eye Drops?

Most people use these drops without experiencing any side effects at all. Because the formulation is preservative free, the risk of irritation associated with repeated use is significantly lower than with preserved alternatives. That said, as with any ophthalmic preparation, some people may notice mild effects, particularly when first starting to use them.

  • Temporary blurred vision immediately after instillation — this usually clears within a few minutes as the drops spread across the eye surface
  • Mild stinging or burning sensation on application — typically brief and settles quickly
  • A watery or wet sensation in the eye immediately after use

What Are the Less Common Side Effects of Numark Preservative Free Moisturising Eye Drops?

Less commonly, a small number of people may experience the following effects. These are not typical but are worth being aware of, particularly if you have sensitive eyes or a history of ocular surface disease.

  • Mild redness of the conjunctiva (the white of the eye)
  • Increased tearing or watering of the eye shortly after use
  • A sticky or slightly uncomfortable feeling around the eyelid margin
  • Sensitivity to light (photophobia) — this is rare

What Are the Serious Side Effects of Numark Preservative Free Moisturising Eye Drops?

Serious side effects are very rare with sodium hyaluronate eye drops. However, you should be alert to the signs of an allergic reaction, which — although uncommon — can occasionally occur with any medicine. Stop using the drops immediately and seek medical attention if you notice any of the following:

  • Significant worsening of eye redness, pain, or swelling
  • Rash around the eye or on the face
  • Swelling of the eyelids, face, lips, or throat
  • Difficulty breathing — this requires emergency medical attention
  • Sudden or significant change in vision

What Should You Do If You Experience Side Effects of These Eye Drops?

If you experience mild side effects such as temporary blurring or brief stinging, these are generally not a cause for concern and should resolve quickly on their own. Avoid rubbing your eyes, as this can worsen irritation. If side effects persist, are severe, or you are concerned about any symptom, stop using the drops and speak to your pharmacist or GP as soon as possible.

You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. This helps improve the safety monitoring of medicines available in the UK.

Can Numark Preservative Free Eye Drops Interact With Other Medicines?

No clinically significant interactions between sodium hyaluronate eye drops and other medicines have been identified. However, if you are using other eye drops — whether prescribed or over the counter — you should wait at least five minutes between instilling each preparation. This prevents one product from diluting or washing out another before it has had time to work. If you are using eye ointments alongside drops, always apply the ointment last. Always inform your pharmacist or GP of all eye preparations you are currently using.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
