What Is Optrex Eye Wash and How Does It Help?

 

If your eyes feel gritty, tired, or irritated after a long day, you are not alone. Millions of people in the UK experience eye discomfort caused by everyday exposure to dust, pollen, smoke, chlorine, and digital screens. Optrex eye wash is a trusted over-the-counter solution designed to gently cleanse and refresh the eyes, helping to wash away the particles and irritants that cause that uncomfortable, scratchy feeling. Available from our eye care collection at Cured Pharmacy for just £4.99, it is an accessible and straightforward option for everyday eye hygiene.

Optrex Multi Action Eye Wash contains witch hazel water (Hamamelis virginiana), a naturally derived ingredient with mild astringent and soothing properties. It is not a medicated eye drop — it works as a cleansing wash rather than a treatment for infection or disease. That distinction matters. If you have symptoms suggesting an eye infection, such as a yellow or green discharge, significant pain, or sudden changes in vision, you should seek advice from a pharmacist or GP rather than relying on an eye wash alone.

 

How Does Optrex Multi Action Eye Wash Work?

 

The mechanism here is largely physical rather than pharmacological. When you bathe your eye with the solution, the liquid flushes across the ocular surface, carrying away foreign particles, allergens, and irritants that have settled on the conjunctiva or cornea. Think of it as a gentle rinse for your eyes — similar in principle to how you might rinse a wound under running water.

  • The solution flows across the eye surface, dislodging dust, pollen, and other debris
  • Witch hazel water provides mild soothing and astringent action to calm irritated tissue
  • The buffered formulation helps maintain a pH compatible with the natural tear film
  • Blinking during the wash helps distribute the solution across the full ocular surface

 

Who Should Use Optrex Multi Action Eye Wash?

 

This product is suitable for adults and children aged two years and over. It is particularly useful for people who spend long hours in front of screens, work in dusty or smoky environments, or suffer from seasonal eye irritation linked to hay fever. If you already manage allergies with antihistamines from our allergy and hay fever range, adding an eye wash to your routine can help address the localised eye symptoms that tablets alone may not fully resolve.

  • Adults and children aged 2 years and over with mild eye irritation
  • People exposed to environmental irritants such as dust, smoke, or chlorine
  • Hay fever sufferers experiencing itchy, watery, or gritty eyes
  • Those wanting a simple daily eye hygiene routine

 

How Does Optrex Multi Action Eye Wash Compare to Eye Drops?

 

Feature Optrex Multi Action Eye Wash Standard Eye Drops
Primary action Cleanses and flushes the eye Lubricates or medicates the eye surface
Volume applied Large volume (full eye bath) Small volume (1–2 drops)
Suitable for removing debris Yes Limited
Contact lens use Remove lenses before use Depends on formulation

 

Is Optrex Multi Action Eye Wash Safe to Store and Use Long-Term?

 

Once opened, Optrex Multi Action Eye Wash should be used within 28 days. This is important — using an eye wash beyond its discard date increases the risk of microbial contamination, which could cause rather than relieve eye problems. Store the bottle below 25°C, away from direct sunlight, and keep it out of reach of children. Do not refrigerate.

It is worth noting that optrex eye wash is not a substitute for professional eye care. If your symptoms persist beyond 48 hours, worsen, or are accompanied by pain, photophobia, or vision changes, stop use and consult a healthcare professional promptly. The NHS advises seeking urgent attention for any sudden or severe eye symptoms.

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 Optrex Multi Action Eye Wash

 

What Is Optrex Multi Action Eye Wash and What Is It Used For?

 

Optrex Multi Action Eye Wash is an over-the-counter ocular cleansing solution containing witch hazel water (Hamamelis virginiana). It is used to soothe, cleanse, and refresh eyes that feel sore, tired, gritty, or irritated. Common triggers include prolonged screen use, exposure to dust, smoke, chlorine from swimming pools, and airborne allergens such as pollen. The product is classified as a General Sale List (GSL) medicine in the UK, meaning it can be purchased without a prescription from pharmacies, supermarkets, and online retailers.

It is important to understand what this product does not do. It is not an antibiotic, antiviral, or anti-inflammatory medicine. It will not treat conjunctivitis caused by bacterial or viral infection, nor will it manage conditions such as glaucoma or uveitis. If you are unsure whether your symptoms require medical attention, the NHS recommends speaking to a pharmacist as a first point of contact for eye concerns.

 

What Do You Need to Know Before Using Optrex Multi Action Eye Wash?

 

Before using this product, read the following carefully. There are situations where use is not appropriate or where extra caution is needed.

Do not use Optrex Multi Action Eye Wash if:

  • You are allergic to witch hazel or any other ingredient in the formulation
  • You have a known eye infection (bacterial, viral, or fungal)
  • You have had recent eye surgery — always seek medical advice first
  • The tamper-evident seal on the bottle is broken before first use
  • The solution has been open for more than 28 days

Use with caution if:

  • You wear contact lenses — always remove them before use and wait at least 15 minutes before reinserting soft lenses
  • You are pregnant or breastfeeding — consult your GP or midwife before use
  • You are using this product in a child under 2 years of age — seek medical advice first

Known drug interactions:

  • No clinically significant drug interactions are currently known for topical witch hazel eye wash
  • If you are using prescribed eye drops or ointments, leave at least 5–10 minutes between applications and use the eye wash first

 

How Should You Use Optrex Multi Action Eye Wash?

 

Using the product correctly is essential for both safety and effectiveness. The eye bath cup provided with the product should be cleaned thoroughly before and after each use. Never share your eye bath with another person, as this risks cross-contamination.

  1. Wash your hands thoroughly with soap and water before handling the product
  2. Remove contact lenses if worn
  3. Fill the eye bath to the halfway mark with Optrex Multi Action Eye Wash solution
  4. Tilt your head forward and place the eye bath firmly over your eye, creating a gentle seal
  5. Tilt your head back slowly, keeping the eye bath in place, and open your eye
  6. Blink several times to allow the solution to wash across the full eye surface
  7. Discard the used solution — never reuse it
  8. Repeat with fresh solution for the other eye if needed
  9. Rinse the eye bath with clean water after use and allow to dry
Indication Age Group Dose Frequency
Sore, tired, or irritated eyes Adults and children aged 2+ Fill eye bath to halfway mark Up to 3 times daily
Post-exposure cleansing (e.g. after swimming) Adults and children aged 2+ Fill eye bath to halfway mark As needed

 

What Are the Possible Side Effects of Optrex Multi Action Eye Wash?

 

Side effects with this product are uncommon when used as directed. However, as with any product applied to the eye, some people may experience a reaction. If you notice any of the following, stop use and seek advice from a pharmacist or GP. You can find further first aid guidance in our first aid collection if needed.

Common side effects:

  • Mild, temporary stinging or burning sensation immediately after use
  • Transient blurred vision lasting a few seconds after bathing
  • Watering of the eye immediately after use

Less common side effects:

  • Redness or increased irritation — may indicate sensitivity to an ingredient
  • Swelling of the eyelid (angioedema) — rare; seek urgent medical attention if this occurs
  • Allergic conjunctivitis — discontinue use immediately and consult a healthcare professional

The NHS advises that any sudden, severe, or worsening eye symptoms — including significant pain, photophobia, or vision disturbance — require prompt medical assessment rather than self-treatment.

 

How Should You Store Optrex Multi Action Eye Wash?

 

Correct storage helps maintain the safety and integrity of the solution. Improper storage, particularly after opening, can allow microbial contamination that could harm your eyes. If you use other eye care products regularly, it is worth reviewing our broader eye care range to ensure everything you use is stored and used correctly.

  • Store below 25°C in a cool, dry place
  • Do not refrigerate
  • Keep away from direct sunlight and heat sources
  • Keep the bottle tightly closed when not in use
  • Discard the solution 28 days after first opening — write the opening date on the bottle
  • Keep out of the reach and sight of children
  • Do not use after the expiry date printed on the bottle

Frequently Asked Questions

Where can I buy Optrex Multi Action Eye Wash online in the UK?

You can buy Optrex Multi Action Eye Wash directly from Cured Pharmacy for just £4.99 with fast UK delivery. It is a General Sale List medicine, so no prescription is needed. Browse our full eye care collection for related products too.

How does Optrex Multi Action Eye Wash work in the eye?

The solution works by physically flushing irritants — such as dust, pollen, smoke, and chlorine — from the surface of the eye. The witch hazel water base provides mild soothing and astringent action to calm the conjunctiva. It does not treat infection or deliver a pharmacological drug to the eye.

How do I use Optrex Multi Action Eye Wash step by step?

Fill the included eye bath to the halfway mark, tilt your head forward, place the bath over your eye, then tilt your head back and blink several times. Discard the used solution and repeat with fresh solution for the other eye if needed. Always wash your hands before use and clean the eye bath after each application.

How many times a day can I use Optrex eye wash?

You can use Optrex Multi Action Eye Wash up to three times daily for sore or irritated eyes. If your symptoms have not improved after 48 hours of regular use, stop and speak to a pharmacist or GP. Overuse is unlikely to cause harm but will not speed up recovery if an underlying condition is present.

Can I use Optrex eye wash if I wear contact lenses?

You must remove your contact lenses before using Optrex Multi Action Eye Wash. After use, wait at least 15 minutes before reinserting soft contact lenses. Hard or rigid gas-permeable lenses should also be removed prior to use — check with your optician if you are unsure.

What are the side effects of Optrex Multi Action Eye Wash?

Side effects are uncommon but may include a brief stinging or burning sensation immediately after use, temporary blurred vision, or mild watering of the eye. Rarely, some people may experience increased redness or signs of an allergic reaction such as eyelid swelling. If any of these persist or worsen, stop use and consult a healthcare professional.

Is Optrex Multi Action Eye Wash safe to use during pregnancy?

Optrex Multi Action Eye Wash is applied topically to the eye and is not absorbed into the bloodstream in any meaningful way, so it is generally considered low risk during pregnancy. However, you should always check with your GP or midwife before using any medicine when pregnant or breastfeeding. This is standard advice for all over-the-counter products.

Can children use Optrex Multi Action Eye Wash?

Yes — Optrex Multi Action Eye Wash is suitable for children aged 2 years and over. For children under 2, you should seek medical advice before use. Always supervise children during use and ensure the eye bath is cleaned thoroughly between applications.

How long can I use Optrex Multi Action Eye Wash for?

Once opened, the bottle should be discarded after 28 days regardless of how much solution remains. For ongoing eye irritation lasting more than a few days, it is worth speaking to a pharmacist to rule out an underlying condition. Optrex eye wash is intended for short-term symptomatic relief rather than long-term daily use.

What is the difference between Optrex eye wash and Optrex eye drops?

Eye wash solutions deliver a large volume of fluid to physically flush the eye, making them ideal for removing debris and irritants. Eye drops deliver a small, precise volume of active ingredient for targeted lubrication or medication. The two products serve different purposes and can be used alongside each other if needed — apply the eye wash first, then wait a few minutes before using drops.

Will Optrex Multi Action Eye Wash treat conjunctivitis?

No — Optrex Multi Action Eye Wash is not a treatment for conjunctivitis. It does not contain antibiotics or antivirals and will not clear a bacterial or viral eye infection. If you have symptoms of conjunctivitis such as sticky discharge, significant redness, or crusting of the eyelids, speak to a pharmacist or GP for appropriate treatment advice.

Can I use Optrex eye wash after swimming?

Yes — using Optrex Multi Action Eye Wash after swimming is a practical way to flush chlorine and other pool chemicals from the eye surface. This can help reduce the redness and irritation that many swimmers experience. Simply use the eye bath as directed as soon as possible after leaving the pool.

What are the alternatives to Optrex Multi Action Eye Wash?

Alternatives include other branded eye wash solutions, sterile saline eye wash products, and lubricating eye drops for dry eye symptoms. If your eye irritation is linked to hay fever, you might also benefit from antihistamine eye drops or oral antihistamines — explore our allergy and hay fever range for options. Always choose the product most suited to your specific symptoms.

What are the latest findings on eye wash solutions for irritated eyes?

Current clinical guidance supports the use of ocular irrigation for removing surface irritants and allergens from the eye. The NHS recommends rinsing the eye with clean water or a sterile eye wash solution as a first-line response to mild eye irritation from foreign bodies or chemical exposure. There is no evidence that regular use of eye wash solutions causes harm when used as directed.

How should I store Optrex Multi Action Eye Wash correctly?

Store the bottle below 25°C in a cool, dry place away from direct sunlight. Do not refrigerate. Once opened, write the date on the bottle and discard any remaining solution after 28 days. Keep the bottle tightly closed between uses and out of reach of children at all times.

How Should You Use Optrex Multi Action Eye Wash?

Using Optrex Multi Action Eye Wash correctly ensures you get the most benefit while keeping your eyes safe. Always wash your hands thoroughly before handling the product, and make sure the eye bath cup is clean before each use. Never share the eye bath with another person.

What Is the Correct Dose of Optrex Multi Action Eye Wash?

There is no fixed volume dose as such — the eye bath is filled to the halfway mark each time, which provides sufficient solution to bathe the eye thoroughly. The table below summarises recommended use by indication and age group.

When Is the Best Time to Use Optrex Multi Action Eye Wash?

There is no single "best" time — use the eye wash whenever your eyes feel sore, gritty, or irritated. Many people find it helpful first thing in the morning if their eyes feel uncomfortable on waking, or after returning indoors on high pollen days. If you have been swimming, using it promptly after leaving the pool helps flush chlorine before it causes prolonged irritation.

If you also use prescribed eye drops or other eye preparations, apply the eye wash first and wait at least five to ten minutes before applying any other product. This prevents the wash from diluting or removing your other medication before it has had time to work.

How Long Can You Use Optrex Multi Action Eye Wash For?

Optrex Multi Action Eye Wash is intended for short-term use to relieve mild, temporary eye irritation. Once opened, the bottle must be discarded after 28 days — write the opening date on the label as a reminder. If your symptoms persist beyond 48 hours, do not improve with regular use, or are accompanied by pain, discharge, or changes in vision, stop using the product and seek advice from a pharmacist or GP.

Prolonged or recurrent eye irritation may indicate an underlying condition that requires proper diagnosis and treatment rather than ongoing self-management with an eye wash alone.

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

What Are the Most Common Side Effects of Optrex Multi Action Eye Wash?

Most people use Optrex Multi Action Eye Wash without experiencing any side effects. When reactions do occur, they are usually mild and short-lived. The most commonly reported effects are related to the physical sensation of the wash rather than a true adverse reaction to the ingredients.

  • Mild, temporary stinging or burning sensation immediately after bathing the eye
  • Transient blurred vision lasting a few seconds after use
  • Increased watering of the eye immediately after application
  • Mild redness that settles quickly after use

What Are the Less Common Side Effects of Optrex Multi Action Eye Wash?

Less commonly, some individuals may experience a reaction that suggests sensitivity to one of the ingredients in the formulation. If any of the following occur, stop using the product and consult a pharmacist or GP before continuing.

  • Persistent or worsening redness of the eye or surrounding skin
  • Increased itching or discomfort after use rather than relief
  • Swelling of the eyelid or surrounding tissue
  • A feeling of grittiness that worsens rather than improves after washing

What Are the Serious Side Effects of Optrex Multi Action Eye Wash?

Serious side effects are rare with this product. However, you should seek urgent medical attention if you experience any of the following after use, as they may indicate a severe allergic reaction (anaphylaxis) or a separate underlying eye condition that requires prompt treatment.

  • Significant swelling of the eyelids, face, or throat
  • Sudden or severe eye pain
  • Sudden changes in vision or loss of vision
  • Sensitivity to light (photophobia) that develops or worsens

The NHS advises that any sudden, severe, or rapidly worsening eye symptoms should be assessed urgently — do not attempt to self-treat these with an over-the-counter eye wash.

What Should You Do If You Experience Side Effects?

If you notice a mild reaction such as brief stinging or temporary blurring, this is usually normal and will settle within a minute or two. You do not need to stop using the product unless the sensation is severe or persistent. However, if you experience any sign of an allergic reaction — such as eyelid swelling, hives, or difficulty breathing — stop use immediately and seek emergency medical help.

You can report suspected side effects from any medicine, including over-the-counter products, to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. This helps regulators monitor the safety of medicines used across the UK.

Can Optrex Multi Action Eye Wash Interact With Other Medicines?

No clinically significant drug interactions are currently known for Optrex Multi Action Eye Wash. Because it is applied topically to the eye surface and is not absorbed into the bloodstream, systemic interactions with oral medicines are not expected. If you are using prescribed eye drops, ointments, or other ocular preparations, apply the eye wash first and wait at least five to ten minutes before applying your other product. This prevents the wash from diluting or displacing your prescribed medicine before it has had time to act. Always inform your pharmacist or GP about all products you are using, including over-the-counter items.

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