What Is ReNu MPS Multi-Purpose Solution?

 

If you wear soft contact lenses, keeping them clean and safe to wear is non-negotiable. The ReNu MPS multi-purpose solution from Bausch & Lomb is a well-established contact lens care product that cleans, rinses, disinfects, and stores soft lenses — all in one bottle. At just 60ml, it's compact enough for travel yet effective enough for your everyday lens care routine. You can find it alongside other trusted products in our eye care collection.

Bausch & Lomb has been a recognised name in eye health for decades. ReNu MPS is designed specifically for soft contact lenses, including silicone hydrogel lenses, and is available over the counter without a prescription. It's a practical, no-fuss solution for anyone who wants reliable lens hygiene without juggling multiple products.

 

How Does ReNu MPS Work to Clean and Disinfect Lenses?

 

ReNu MPS works through a combination of surfactant cleaning agents and a low-concentration disinfectant called polyhexamethylene biguanide (PHMB). Together, these ingredients tackle the main causes of lens contamination — protein deposits, lipid build-up, and microbial contamination. Here's what happens during the cleaning process:

  • Cleaning: Surfactants loosen and lift protein and lipid deposits from the lens surface during the rub-and-rinse step.
  • Rinsing: The solution flushes away loosened debris and residual cleaning agents before storage.
  • Disinfection: PHMB (0.0001%) kills bacteria and other micro-organisms during the minimum 4-hour soak period.
  • Storage: The lens sits in a conditioning environment that helps maintain lens hydration and comfort.

The rub step is important — even with a "no-rub" labelled solution, the NHS and contact lens practitioners recommend physically rubbing lenses to improve cleaning efficacy and reduce the risk of eye infections.

 

Who Should Use ReNu MPS Contact Lens Solution?

 

ReNu MPS is suitable for most adults and older teenagers who wear soft contact lenses on a daily or extended-wear basis. It is not appropriate for everyone, so it's worth checking the following:

  • Adults and teenagers wearing soft (hydrogel or silicone hydrogel) contact lenses
  • People looking for a single-bottle solution that covers all lens care steps
  • Travellers who need a compact, convenient lens care option
  • Those who have been advised by their optician to use a multi-purpose solution

It is not suitable for use with rigid gas-permeable (RGP) or hard contact lenses. Children should only use contact lens solutions under adult supervision and on the advice of an optician.

 

How Does ReNu MPS Compare to Other Contact Lens Solutions?

 

Feature ReNu MPS 60ml Saline Solution
Cleans lenses Yes No
Disinfects lenses Yes (PHMB) No
Stores lenses Yes Not recommended
Suitable for soft lenses Yes Rinse only
Travel-friendly size Yes (60ml) Varies

 

Is ReNu MPS Safe to Store and Travel With?

 

The 60ml size of ReNu MPS multi-purpose solution falls within the 100ml liquid limit for carry-on luggage under UK airport security rules, making it a practical choice for frequent travellers. Store the bottle below 25°C, away from direct sunlight, and always replace the cap tightly after use to prevent contamination. Once opened, use the solution within the timeframe stated on the packaging — typically 90 days.

Never top up old solution in your lens case with fresh solution. Always discard the used solution, rinse the case with fresh ReNu MPS, and allow it to air dry face-down on a clean tissue. Replace your lens case at least every three months to reduce infection risk. Good lens hygiene is one of the most effective ways to protect your eye health.

This product is a medical device. Speak to your optician or pharmacist before using if you have a history of eye infections, dry eye syndrome, or are currently using any eye drops or ocular medications.

What Is ReNu MPS and What Is It Used For?

 

Bausch & Lomb ReNu MPS Multi-Purpose Solution is a contact lens care product used to clean, rinse, disinfect, and store soft contact lenses. It is intended for use with soft hydrogel and silicone hydrogel lenses only. The solution is not a medicine but a CE-marked medical device regulated for safety and performance. It is available over the counter and does not require a prescription.

ReNu MPS is used as part of a daily lens care routine to remove protein and lipid deposits that accumulate on lens surfaces during wear, and to eliminate micro-organisms that could cause eye infections if lenses are reinserted without proper disinfection.

 

What Do You Need to Know Before Using ReNu MPS?

 

Before using this solution, read the following warnings carefully:

  • Do not use with rigid gas-permeable (RGP) or hard contact lenses.
  • Do not instil the solution directly into your eyes — it is for lens care only.
  • Do not use if you have a known sensitivity or allergy to any of the ingredients, including PHMB.
  • Do not use if the tamper-evident seal is broken before first use.
  • Do not use after the expiry date printed on the bottle.
  • Stop use and consult an optician or GP if you experience persistent eye redness, pain, or discharge.
  • Keep out of reach of children.
  • If you have a history of recurrent eye infections or dry eye, seek advice from your optician before use.

Known interactions:

  • No clinically significant drug interactions are known for this product.
  • If you use medicated eye drops, insert them at least 15 minutes before putting in your contact lenses, and follow your prescriber's guidance on lens wear during treatment.

 

How Should You Use ReNu MPS Correctly?

 

Always wash and dry your hands thoroughly before handling contact lenses or the solution bottle. Follow these steps each time you clean your lenses:

  1. Place the lens in the palm of your hand.
  2. Apply 3–4 drops of ReNu MPS to each side of the lens.
  3. Rub the lens gently with your fingertip for approximately 20 seconds on each side.
  4. Rinse each side of the lens thoroughly with ReNu MPS for 10 seconds.
  5. Place the lens in a clean lens case.
  6. Fill the case with fresh ReNu MPS until the lens is fully submerged.
  7. Close the case and leave to soak for a minimum of 4 hours (overnight is ideal).
  8. Before inserting lenses, rinse with a few drops of fresh ReNu MPS if desired.

What Are the Possible Side Effects of ReNu MPS?

 

ReNu MPS is generally well tolerated. However, as with any contact lens care product, some people may experience reactions. If you notice any of the following, remove your lenses immediately and seek advice from an optician or GP. You can also find general guidance on eye health through our eye care range.

Common side effects:

  • Mild, temporary eye irritation or stinging on lens insertion
  • Temporary blurred vision immediately after inserting lenses
  • Mild lens discomfort during initial use

Frequently Asked Questions

Where can I buy ReNu MPS multi-purpose solution online in the UK?

You can buy Bausch & Lomb ReNu MPS multi-purpose solution directly from Cured Pharmacy, a GPhC-registered UK online pharmacy. It is available without a prescription as an over-the-counter contact lens care product. Browse our full eye care collection for more lens care options and accessories.

How does ReNu MPS work to clean and disinfect contact lenses?

ReNu MPS uses a surfactant system to loosen and remove protein and lipid deposits from soft lens surfaces during the rub-and-rinse step. The disinfecting agent polyhexamethylene biguanide (PHMB) then kills bacteria and micro-organisms during the soak period. Together, these actions ensure your lenses are clean, safe, and comfortable to wear the next day.

How do I use ReNu MPS step by step?

After washing your hands, place each lens in your palm and apply 3–4 drops of ReNu MPS, then rub gently for 20 seconds per side. Rinse each lens thoroughly with the solution, then place in a clean case filled with fresh ReNu MPS and soak for at least 4 hours. Always use fresh solution — never top up old solution in the case.

Can I use ReNu MPS with silicone hydrogel contact lenses?

Yes, ReNu MPS is compatible with silicone hydrogel soft contact lenses as well as standard hydrogel lenses. It is not suitable for rigid gas-permeable (RGP) or hard lenses. If you are unsure about your lens type, check with your optician before use.

What are the side effects of ReNu MPS contact lens solution?

Most people tolerate ReNu MPS well, but some may experience mild, temporary stinging or blurred vision when inserting lenses. Less commonly, eye redness, increased lens awareness, or an allergic reaction to solution ingredients may occur. If symptoms persist or worsen, remove your lenses and consult an optician or GP promptly.

How long should I soak my lenses in ReNu MPS?

Lenses must soak in ReNu MPS for a minimum of 4 hours to achieve effective disinfection. Overnight soaking is the most practical option for daily lens wearers and is perfectly safe. Never shorten the soak time, as this reduces the disinfection efficacy and increases infection risk.

Is it safe to use ReNu MPS every day?

Yes, ReNu MPS is formulated for daily use as part of a regular contact lens care routine. It is gentle on soft lens materials while providing effective cleaning and disinfection with each use. Replace your lens case at least every three months and always use fresh solution to maintain hygiene standards.

What is the difference between ReNu MPS and saline solution?

ReNu MPS is a multi-purpose solution that cleans, disinfects, rinses, and stores contact lenses in a single product. Saline solution only rinses lenses and has no disinfecting properties, so it cannot be used alone for lens storage or disinfection. For a complete and safe lens care routine, a multi-purpose solution like ReNu MPS is required.

Who is eligible to use ReNu MPS contact lens solution?

ReNu MPS is suitable for adults and older teenagers who wear soft contact lenses, including daily wear and extended wear types. It is not suitable for children without adult supervision and optician guidance, nor for wearers of RGP or hard lenses. People with a known sensitivity to PHMB or other listed ingredients should not use this product.

What happens if I accidentally put ReNu MPS directly in my eye?

ReNu MPS is not formulated for direct instillation into the eye and should not be used as eye drops. If accidental eye contact occurs, rinse your eye thoroughly with clean water and seek advice from a pharmacist or GP if irritation persists. Always keep the bottle away from children to prevent accidental misuse.

How long can I use an opened bottle of ReNu MPS?

Once opened, ReNu MPS should be used within 90 days, even if solution remains in the bottle. Using solution beyond this period may reduce its disinfecting effectiveness and increase contamination risk. Always check the expiry date on the bottle before use and discard if expired.

Can I travel with ReNu MPS in my hand luggage?

Yes, the 60ml bottle of ReNu MPS falls within the 100ml liquid limit permitted in carry-on luggage under UK airport security regulations. Place it in a clear, resealable plastic bag alongside your other liquids when going through security. It is one of the most travel-convenient sizes available for contact lens wearers.

What are the alternatives to ReNu MPS for contact lens care?

Alternatives to ReNu MPS include other multi-purpose solutions such as Opti-Free PureMoist and Biotrue, as well as hydrogen peroxide-based systems like AOSEPT PLUS for those who prefer a preservative-free option. The right choice depends on your lens type, sensitivity, and optician's recommendation. Browse our eye care range to compare available options.

How should I store my ReNu MPS bottle at home?

Store ReNu MPS below 25°C in a cool, dry place away from direct sunlight and heat sources. Always replace the cap tightly after use to prevent contamination and evaporation. Do not freeze the solution or transfer it to another container.

Are there any latest studies or research on ReNu MPS solution?

Bausch & Lomb's ReNu MPS formulation has been evaluated in clinical studies examining its disinfection efficacy against common ocular pathogens, including Acanthamoeba, which is associated with serious contact lens-related infections. Published research supports the importance of the rub-and-rinse step in improving cleaning outcomes compared to no-rub protocols. Always follow current guidance from your optician and the NHS on safe contact lens hygiene practices.

How Should You Use ReNu MPS Multi-Purpose Solution?

Always wash your hands thoroughly with soap and dry them with a lint-free towel before handling your contact lenses or the solution bottle. Avoid touching the bottle tip to any surface, including your fingers or lens case, to prevent contamination.

Follow these steps every time you remove your lenses:

After removing your lenses from the case, empty the old solution, rinse the case with fresh ReNu MPS, and leave it to air dry face-down on a clean tissue. Never reuse solution from the case.

What Is the Correct Dose of ReNu MPS?

There is no fixed "dose" in the traditional sense, but the amount of solution used at each step matters for effective cleaning and disinfection. Using too little solution during the rub or rinse step may reduce cleaning efficacy.

When Is the Best Time to Use ReNu MPS?

The best time to clean and store your lenses with ReNu MPS is immediately after removing them at the end of the day. Cleaning lenses promptly prevents deposits from drying onto the lens surface, which makes them harder to remove.

If you wear lenses on an extended schedule, clean and disinfect them whenever they are removed, even if only briefly. Overnight soaking is the most practical routine for most wearers and ensures the minimum 4-hour disinfection period is comfortably met.

How Long Can You Use ReNu MPS For?

ReNu MPS can be used as part of your ongoing daily lens care routine for as long as you wear soft contact lenses. There is no maximum duration of use, provided you follow the instructions correctly and replace the bottle within 90 days of opening.

If you experience persistent eye discomfort, redness, or changes in vision, stop using your lenses and consult your optician. Regular optician check-ups — typically every 12 months — are recommended for all contact lens wearers to ensure your lenses and care routine remain appropriate for your eyes.

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

What Are the Most Common Side Effects of ReNu MPS?

ReNu MPS is well tolerated by the majority of soft contact lens wearers when used as directed. However, some people do experience mild reactions, particularly when first switching to this solution or if the rub-and-rinse step is not performed thoroughly.

  • Mild, temporary stinging or burning sensation on lens insertion
  • Temporary blurred vision immediately after inserting lenses
  • Slight lens discomfort during the first few uses
  • Mild watering of the eyes

These effects are usually short-lived and resolve within a few minutes of lens insertion. If they persist beyond this, remove your lenses and rinse your eyes with clean water.

What Are the Less Common Side Effects of ReNu MPS?

Less commonly, some wearers may develop a reaction to one or more ingredients in the solution, including the preservative PHMB. These reactions are more likely in people with sensitive eyes or a history of allergic eye conditions.

  • Eye redness or conjunctival injection
  • Increased lens awareness or foreign body sensation
  • Itching or allergic reaction to solution ingredients
  • Contact lens-related papillary conjunctivitis (CLPC) — a condition involving small bumps on the inner eyelid associated with prolonged lens wear or solution sensitivity
  • Lens intolerance — a general feeling that lenses are no longer comfortable to wear

If you notice any of these symptoms, stop using the solution and consult your optician. Switching to a preservative-free hydrogen peroxide system may be recommended in some cases.

What Are the Serious Side Effects of ReNu MPS?

Serious side effects from ReNu MPS itself are rare. However, improper contact lens hygiene — including inadequate cleaning, topping up old solution, or not replacing the lens case regularly — can increase the risk of serious eye infections such as microbial keratitis or Acanthamoeba keratitis. These conditions can cause significant pain, vision loss, and may require urgent medical treatment.

Seek urgent medical attention if you experience any of the following:

  • Sudden or severe eye pain
  • Significant vision changes or loss
  • Profuse eye discharge or crusting
  • Marked swelling of the eyelids or surrounding tissue
  • Extreme sensitivity to light (photophobia)

What Should You Do If You Experience Side Effects?

If you experience mild irritation, remove your lenses immediately and rinse your eyes with clean water. Allow your eyes to rest without lenses for at least 24 hours before attempting to reinsert them. If symptoms resolve, check your lens care technique and ensure you are using fresh solution each time.

For persistent or worsening symptoms, contact your optician or GP. Do not attempt to continue wearing lenses until you have been assessed. In an emergency, attend your nearest NHS urgent eye care service or A&E department.

Can ReNu MPS Interact With Other Eye Products?

No clinically significant drug interactions are known for ReNu MPS. However, if you use medicated eye drops — such as antihistamine drops for allergic conjunctivitis or glaucoma medications — you should insert your eye drops at least 15 minutes before putting in your contact lenses. Some eye drops are not compatible with contact lens wear; always check with your prescriber or pharmacist before using eye drops alongside contact lenses.

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