What Is Hycosan Night Eye Ointment?

 

If you wake up with sore, gritty, or uncomfortable eyes, you are not alone. Dry eye syndrome affects millions of people in the UK, and symptoms often worsen overnight when the eyes are closed and tear production slows. Hycosan night eye ointment is a preservative-free ocular lubricant formulated specifically for overnight use, providing sustained moisture and protection while you sleep. You can find it alongside a wide range of other products in our eye care collection.

Unlike standard eye drops, which clear from the eye surface relatively quickly, this ointment has a thicker consistency that allows it to remain in contact with the ocular surface for longer. That extended contact time is exactly what makes it suited to overnight relief rather than daytime use.

 

How Does Hycosan Night Eye Ointment Work?

 

The ointment works by physically coating the surface of the eye with a protective, lubricating film. This reduces evaporation of the natural tear film and shields the cornea and conjunctiva from friction and environmental irritants during sleep. The key steps in its mechanism are:

  • Applied to the lower conjunctival sac at bedtime, where it spreads across the ocular surface on blinking
  • White soft paraffin and liquid paraffin form a semi-occlusive barrier that retains moisture
  • Wool fat (lanolin) helps the ointment adhere to the eye surface and improves spreadability
  • The preservative-free formulation minimises the risk of irritation or toxicity to the corneal epithelium with regular use

Because it contains no preservatives, it is generally considered suitable for people who use eye preparations frequently and may be sensitive to preservative agents such as benzalkonium chloride.

 

Who Should Use Hycosan Night Eye Ointment?

 

This ointment is intended for adults who experience dry, irritated, or uncomfortable eyes, particularly those whose symptoms are most troublesome on waking. It may be especially useful if daytime eye drops are not providing sufficient relief on their own. Suitable users include:

  • Adults with diagnosed dry eye syndrome or keratoconjunctivitis sicca
  • People whose eyes feel gritty, burning, or sore first thing in the morning
  • Those who have had laser eye surgery or other ocular procedures that affect tear production
  • Individuals who sleep in environments with low humidity, air conditioning, or central heating

It is not recommended for use in children unless specifically directed by a doctor. Always read the label before use.

 

How Does Hycosan Night Eye Ointment Compare to Eye Drops?

 

Feature Hycosan Night Eye Ointment Standard Lubricating Eye Drops
Formulation Paraffin-based ointment Aqueous solution
Duration of action Extended — suitable for overnight use Short — requires frequent reapplication
Preservative-free Yes Varies by product
Suitable for daytime use No — causes blurred vision Yes

 

Is Hycosan Night Eye Ointment Safe to Store and Use Long-Term?

 

Once opened, the tube should be used within six weeks and then discarded, even if product remains. This is standard practice for ophthalmic preparations to reduce the risk of microbial contamination. Store the ointment below 25°C, away from direct sunlight and out of reach of children. Do not use after the expiry date printed on the packaging.

If you are already using other eye preparations, allow at least five minutes between applications. The hycosan night eye ointment should always be applied last if you are using both drops and ointment on the same occasion, as the ointment base can reduce the absorption of other preparations. You may also find it helpful to browse our creams and ointments collection for related topical products.

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 Hycosan Night Eye Ointment

 

What Is Hycosan Night Eye Ointment and What Is It Used For?

 

Hycosan Night Eye Ointment is an over-the-counter ocular lubricant used to relieve the symptoms of dry eye syndrome, particularly during sleep. Dry eye is a common condition in which the eyes do not produce enough tears, or the tears evaporate too quickly, leading to discomfort, a gritty sensation, redness, and sensitivity to light. The NHS notes that dry eye syndrome is more common in older adults and in people who spend long periods looking at screens.

The ointment is preservative-free and contains white soft paraffin, liquid paraffin, and wool fat (lanolin). These ingredients work together to coat and protect the surface of the eye throughout the night, reducing friction and moisture loss. It is not a treatment for the underlying cause of dry eye, but it provides meaningful symptomatic relief.

 

What Do You Need to Know Before Using Hycosan Night Eye Ointment?

 

Before using this ointment, check the following contraindications and warnings carefully:

  • Do not use if you are allergic to white soft paraffin, liquid paraffin, wool fat (lanolin), or any other ingredient in the formulation
  • Do not use whilst wearing contact lenses — remove lenses before application and do not reinsert until the following morning
  • Do not use in children unless directed by a doctor
  • Do not use if the tube seal is broken before first use
  • Consult your GP or pharmacist if you have an eye infection, eye injury, or have recently had eye surgery
  • Stop use and seek medical advice if symptoms worsen or do not improve after 2 days

Regarding drug interactions, no significant interactions with systemic medicines have been identified. However:

  • If you use other eye drops or eye preparations, apply them first and wait at least 5 minutes before applying this ointment
  • The ointment base may reduce the absorption of other ophthalmic preparations if applied simultaneously

 

How Should You Use Hycosan Night Eye Ointment?

 

This ointment is for ophthalmic use only — it must never be swallowed or applied to any other part of the body. Follow these steps carefully each time you use it:

  1. Wash your hands thoroughly with soap and water before handling the tube
  2. Remove contact lenses if worn
  3. Tilt your head back slightly and look upward
  4. Gently pull down your lower eyelid to create a small pocket
  5. Squeeze a small ribbon of ointment (approximately 1 cm) into the lower conjunctival sac — avoid touching the eye or eyelid with the tube tip
  6. Close your eye gently and blink once or twice to spread the ointment across the eye surface
  7. Wipe away any excess ointment from around the eye with a clean tissue
  8. Replace the cap on the tube immediately after use
Indication Age Group Dose Frequency
Dry eye symptom relief Adults Small ribbon (~1 cm) per eye Once nightly at bedtime
Dry eye symptom relief Children Only on medical advice As directed by doctor

 

What Are the Possible Side Effects of Hycosan Night Eye Ointment?

 

Like all medicines, this ointment can cause side effects, although not everyone experiences them. The most frequently reported effect is temporary blurred vision immediately after application — this is expected and is why the ointment is only suitable for bedtime use.

Common side effects:

  • Temporary blurred or hazy vision after application
  • Mild stinging or burning sensation in the eye
  • Sticky feeling around the eyelids on waking

Less common side effects:

  • Redness or irritation of the eye or eyelid
  • Allergic reaction — particularly in those sensitive to lanolin (wool fat)
  • Crusting around the eyelashes

If you experience a severe allergic reaction — including swelling of the face, lips, or throat, or difficulty breathing — stop use immediately and seek emergency medical attention. You can find further guidance on managing eye conditions through our eye care collection.

 

How Should You Store Hycosan Night Eye Ointment?

 

Correct storage helps maintain the safety and effectiveness of the ointment. Follow these instructions:

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and heat sources
  • Keep out of the sight and reach of children
  • Do not use after the expiry date printed on the tube and carton
  • Discard the tube 6 weeks after first opening, even if product remains
  • Do not freeze
  • Do not share the tube with another person — this reduces the risk of cross-contamination

If you are unsure whether a product is still safe to use, speak to your pharmacist. For other topical preparations, you may also wish to explore our allergy and hay fever range, which includes products for eye-related allergy symptoms.

Frequently Asked Questions

Where can I buy Hycosan Night Eye Ointment online in the UK?

You can buy Hycosan Night Eye Ointment directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £6.25. It is available without a prescription as a General Sale Medicine. Browse our full eye care collection for a wider range of dry eye products.

How does Hycosan Night Eye Ointment work in the eye?

The ointment forms a protective, semi-occlusive film over the surface of the eye using white soft paraffin and liquid paraffin as its base. This film reduces evaporation of the natural tear film and shields the cornea from friction and dryness during sleep. Wool fat (lanolin) helps the ointment spread evenly and adhere to the ocular surface throughout the night.

How do I apply Hycosan Night Eye Ointment step by step?

Wash your hands, tilt your head back, and gently pull down your lower eyelid to create a small pocket. Squeeze a small ribbon of ointment (approximately 1 cm) into the lower conjunctival sac without touching the tube tip to your eye. Close your eye gently, blink once to spread the ointment, and wipe away any excess with a clean tissue before going to sleep.

When is the best time to use Hycosan Night Eye Ointment?

This ointment is designed exclusively for use at bedtime, immediately before you go to sleep. Because it causes temporary blurred vision after application, it is not safe or practical to use during the day. Applying it as the very last step in your evening routine ensures it works throughout the night when your eyes are most vulnerable to dryness.

What are the side effects of Hycosan Night Eye Ointment?

The most common side effect is temporary blurred vision immediately after application, which is entirely expected and resolves naturally on waking. Some people also notice a mild stinging sensation or a sticky feeling around the eyelids in the morning. If you experience persistent redness, swelling, or signs of an allergic reaction, stop use and speak to a pharmacist or GP.

Can I use Hycosan Night Eye Ointment with contact lenses?

No — you must remove contact lenses before applying this ointment and should not reinsert them until the following morning. The paraffin-based ointment can damage the material of both soft and rigid contact lenses. If you wear lenses during the day and need daytime dry eye relief, speak to your pharmacist about a suitable preservative-free eye drop instead.

What happens if I accidentally use too much Hycosan Night Eye Ointment?

Using slightly more ointment than recommended is unlikely to cause serious harm, but it may result in more pronounced blurred vision and a greater sticky residue around the eyelids on waking. If you accidentally get ointment in your mouth or swallow any, contact NHS 111 or your nearest pharmacist for advice. Always keep the tube out of reach of children.

Who is eligible to use Hycosan Night Eye Ointment?

This ointment is suitable for adults who experience dry, irritated, or uncomfortable eyes, particularly those whose symptoms are worst on waking. It is not recommended for children unless a doctor has specifically advised its use. People with known allergies to lanolin (wool fat) or paraffin should avoid this product and seek an alternative formulation.

How long can I use Hycosan Night Eye Ointment for?

The ointment can be used on an ongoing basis for the management of chronic dry eye symptoms, but the tube must be discarded six weeks after first opening regardless of how much remains. If your symptoms do not improve after two days of use, or if they worsen at any point, you should consult a pharmacist or GP. Long-term dry eye management may also benefit from a combination of daytime drops and this overnight ointment.

What are the ingredients in Hycosan Night Eye Ointment?

The active ingredients are white soft paraffin, liquid paraffin, and wool fat (also known as lanolin). The formulation is preservative-free, which makes it a good option for people who use eye preparations regularly and may be sensitive to preservatives such as benzalkonium chloride. There are no added dyes or fragrances in the formulation.

What are the alternatives to Hycosan Night Eye Ointment?

Other preservative-free ocular lubricant ointments available in the UK include Lacri-Lube and VitA-POS, both of which have a similar paraffin-based formulation. For daytime dry eye relief, lubricating eye drops containing sodium hyaluronate or carmellose are widely used alternatives. You can explore a range of options in our eye care collection.

Can I use Hycosan Night Eye Ointment if I have had laser eye surgery?

Dry eye is a very common side effect following laser refractive surgery such as LASIK or LASEK, and ocular lubricants are frequently recommended as part of post-operative care. However, you should always follow the specific guidance given by your eye surgeon regarding which products are appropriate and when to start using them. Do not use any eye preparation after surgery without first confirming it is suitable with your clinical team.

Is Hycosan Night Eye Ointment suitable during pregnancy or breastfeeding?

There is no specific evidence of harm from topical ocular paraffin-based ointments during pregnancy or breastfeeding, as systemic absorption is minimal. However, as with all medicines, you should consult your GP or midwife before using any new product during pregnancy or whilst breastfeeding. Your pharmacist can also provide guidance tailored to your individual circumstances.

What are the latest studies on dry eye treatment with ocular ointments?

Current clinical guidance, including that from the NHS and the British National Formulary, supports the use of preservative-free ocular lubricants — including ointments — as a first-line approach to managing dry eye syndrome. Research continues to explore the role of the lipid layer of the tear film in dry eye, reinforcing the rationale for paraffin-based ointments that supplement this layer overnight. Speak to your GP or ophthalmologist if you would like to discuss the most up-to-date management options for your specific condition.

Can I use Hycosan Night Eye Ointment alongside other eye drops during the day?

Yes — many people use daytime lubricating eye drops alongside this overnight ointment as part of a complete dry eye management routine. If you are using both on the same occasion, always apply eye drops first and wait at least five minutes before applying the ointment. The ointment should always be the last preparation applied, as its thick base can reduce the effectiveness of other drops if applied beforehand.

How Should You Use Hycosan Night Eye Ointment?

This ointment is applied directly to the eye at bedtime. It is for ophthalmic use only and should never be swallowed or applied to any other area of the body. Follow these steps each time you use it to ensure safe and effective application.

Always wash your hands before and after handling the tube, and replace the cap immediately after use to prevent contamination.

What Is the Correct Dose of Hycosan Night Eye Ointment?

The standard dose is a small ribbon of ointment applied to each affected eye once nightly at bedtime. Do not apply more than directed — using excess ointment will not improve results and may increase the likelihood of a sticky residue on waking.

The following table summarises the recommended dosing by indication and age group.

When Is the Best Time to Use Hycosan Night Eye Ointment?

Apply this ointment immediately before going to sleep. Because the thick consistency causes temporary blurred vision after application, it is not suitable for use during waking hours. Making it the final step in your bedtime routine — after removing contact lenses and applying any daytime eye drops — ensures it works throughout the night when tear production naturally slows.

If you use other eye preparations, apply them first and wait at least five minutes before applying this ointment. The ointment should always be the last product applied to the eye.

How Long Can You Use Hycosan Night Eye Ointment For?

This ointment can be used on an ongoing basis as part of a dry eye management routine. However, the tube must be discarded six weeks after first opening, even if product remains, to reduce the risk of microbial contamination. If your symptoms do not improve after two days of use, or if they worsen at any point, stop using the ointment and consult a pharmacist or GP.

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

This product is absolutely fantastic. It works perfect for my dry eyes at night. God knows i have tried so many products, non of which worked for me. No more dry eyes here 😃.

What Are the Most Common Side Effects of Hycosan Night Eye Ointment?

The most frequently reported side effect is temporary blurred or hazy vision immediately after application. This is an expected consequence of the thick ointment base spreading across the ocular surface and is not a cause for concern — it resolves naturally on waking. Because of this effect, the ointment must only be used at bedtime.

  • Temporary blurred or hazy vision after application
  • Mild stinging or burning sensation in the eye
  • Sticky or crusty feeling around the eyelids on waking
  • Slight watering of the eye immediately after application

What Are the Less Common Side Effects of Hycosan Night Eye Ointment?

Less commonly, some people experience localised irritation or a mild allergic response, particularly those with a sensitivity to lanolin (wool fat), which is one of the ingredients. If you have previously reacted to lanolin-containing products — such as certain moisturisers or lip balms — you should check with your pharmacist before using this ointment.

  • Redness or irritation of the eye or surrounding eyelid skin
  • Allergic contact dermatitis around the eyelid area
  • Crusting or matting of the eyelashes
  • Sensation of a foreign body in the eye

What Are the Serious Side Effects of Hycosan Night Eye Ointment?

Serious side effects are rare with this type of topical ocular preparation. However, you should stop using the ointment immediately and seek urgent medical attention if you experience any of the following, as they may indicate a severe allergic reaction or a separate eye condition requiring treatment.

Signs to watch for include sudden or significant worsening of eye pain, marked increase in redness, swelling of the eyelids or face, difficulty breathing, or any change in vision that does not resolve after waking. These symptoms are not typical of a normal response to this ointment.

What Should You Do If You Experience Side Effects?

For mild side effects such as temporary blurring or a sticky sensation, no specific action is needed — these typically resolve on their own. If you experience persistent irritation, redness, or discomfort that does not improve after stopping use, contact your pharmacist or GP for advice. Do not continue using the ointment if you suspect an allergic reaction.

If you accidentally get ointment in your mouth or a child swallows any, contact NHS 111 immediately. Always store the tube out of reach of children.

Can Hycosan Night Eye Ointment Interact With Other Medicines?

No significant interactions with systemic medicines have been identified for this product. The main interaction to be aware of is with other ophthalmic preparations — the ointment base can reduce the absorption of eye drops if applied at the same time. Always apply eye drops first, wait at least five minutes, and then apply the ointment last. This applies to both prescription and over-the-counter eye preparations.

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