Optrex Multi Action Eye Wash is a 100ml eye wash with a reusable eye bath, for rinsing and soothing eyes that are tired, gritty, uncomfortable or have had dust, pollen, grit or smoke in them. It cleanses the eye surface mechanically — flushing the irritant away rather than medicating it.

What is Optrex Eye Wash?

It is a mild, buffered rinsing solution containing distilled witch hazel (hamamelis) alongside boric acid, sodium borate and glycerine in purified water, with benzalkonium chloride as a preservative. Witch hazel is a traditional astringent used to soothe the eye surface. The solution is supplied with an eye bath — the small cup that lets you bathe the whole eye rather than dropping liquid into it.

What is it used for?

  • Flushing out dust, grit, pollen, smoke or other loose particles
  • Tired, gritty or uncomfortable eyes at the end of a long day
  • Eyes irritated by air conditioning, wind or a dusty environment
  • Rinsing the eye surface after a day outdoors in pollen season

It is a cleansing wash, not a medicine for a condition. It will not treat an eye infection, and it is not an allergy treatment — though rinsing pollen off the eye surface can be a useful adjunct alongside an anti-allergy eye drop during hay fever season.

How to use the eye bath

  • Wash and dry your hands, and check the bottle seal is intact before first use.
  • Rinse the eye bath with the solution before you use it.
  • Fill the eye bath about one third full.
  • Bend your head forward, press the eye bath firmly over the eye to make a seal, then tilt your head back with the eye open.
  • Rock your head gently side to side for at least 30 seconds so the solution washes across the whole eye surface.
  • Bend forward to remove the bath, discard the used solution, and repeat for the other eye with fresh solution.
  • Rinse the eye bath after use and let it dry.

Never re-use the solution from the eye bath between eyes — that is how an infection or an irritant gets transferred from one eye to the other.

Contact lenses, storage and shelf life

Remove contact lenses before using the wash and leave at least 15 minutes before putting them back in. Store below 25°C, keep out of reach of children, and discard any remaining solution 28 days after opening.

Eye wash or eye drops — which do you need?

An eye wash rinses the surface and flushes things off it: use it when something is in your eye or the eye feels gritty and dirty. Eye drops stay on the eye and do a job there: lubricate a dry eye (Hylo-Forte), calm an allergic response, or reduce redness (Optrex Bloodshot Eye Drops). If your eyes are dry rather than dirty, a wash will feel pleasant briefly but will not fix the tear film — Optrex ActiMist is the better choice there. See the full eye care range.

When not to rely on an eye wash

Get urgent advice from an optometrist, GP or 111 if something has struck the eye at speed, if you cannot flush out whatever is in it, if a chemical has gone into the eye (irrigate immediately with plenty of clean water and seek help), or if there is pain, reduced vision, light sensitivity or a yellow-green discharge. An eye wash is for minor irritation only.

Optrex Eye Wash FAQs

What is Optrex Multi Action Eye Wash used for?
It is used to rinse and soothe eyes that are tired, gritty, uncomfortable or irritated, and to flush out loose particles such as dust, grit, pollen and smoke. It cleanses the eye surface rather than treating a medical condition.
How do you use an eye bath properly?
Wash your hands, rinse the eye bath with the solution, then fill it about a third full. Bend your head forward, press the bath over the eye to form a seal, tilt your head back with the eye open and rock gently side to side for at least 30 seconds. Discard the used solution and repeat with fresh solution for the other eye.
Can I use the same solution for both eyes?
No. Always discard the used solution and refill the eye bath with fresh wash for the second eye. Re-using it can transfer an irritant or an infection from one eye to the other.
How often can I use Optrex Eye Wash?
It can be used as needed for minor irritation. If your eyes need rinsing every day, it is worth finding out why – persistent grittiness is more often dry eye, blepharitis or allergy, and each of those has a treatment that works better than rinsing.
Does eye wash help with dry eyes?
Not really. A wash rinses the surface and feels soothing briefly, but it does not replace or stabilise the tear film, so the dryness returns. A lipid spray such as Optrex ActiMist or a lubricating drop such as Hylo-Forte addresses the actual problem.
Can I use it with contact lenses?
Remove your lenses before using the wash and wait at least 15 minutes before putting them back in.
How long does it last once opened?
Discard any remaining solution 28 days after opening the bottle. Store below 25 degrees C and keep it out of reach of children.
Will Optrex Eye Wash treat conjunctivitis?
No. It contains no antibiotic or anti-infective. If you have a sticky yellow or green discharge, pain, light sensitivity or reduced vision, see a pharmacist, optometrist or GP rather than relying on a wash.
Is it suitable for children?
Check the pack before using it on a child, and ask your pharmacist – using an eye bath properly needs a degree of cooperation that younger children often cannot manage. For a child with something in the eye, seek advice rather than improvising.
What should I do if a chemical splashes in my eye?
Do not wait to find an eye wash. Irrigate immediately with plenty of clean running water for at least 15 minutes, holding the eyelid open, and get urgent medical help. An eye wash bottle is not the right tool for a chemical injury.
