Lens Compatibility
Check that the care system is intended for the reusable lens material and schedule you use.
Lens Solutions
Contact lens solutions are care products, not a substitute for proper lens fitting.
This page focuses on the liquids and care systems used with reusable contact lenses. It is separate from the Contact Lenses page, which covers the lenses themselves.
Direct Answer
What are contact lens solutions used for?
Depending on the product, they may be used for cleaning, rinsing, disinfecting and storing compatible reusable contact lenses.
Contact-lens care systems are product-specific. Multipurpose solutions and peroxide-based systems have different instructions and safety requirements. Use only a care system compatible with your lenses and follow the exact product directions for cleaning, disinfection, storage and neutralisation where required.
What To Consider
Care systems require strict product-specific use.
Contact-lens solution is not interchangeable with water, saliva or arbitrary household liquids.
Disinfection Time
Reusable lenses may require a minimum soaking or disinfection time.
Case Hygiene
Lens cases should be handled, cleaned and replaced according to appropriate care guidance.
Peroxide Safety
Hydrogen-peroxide systems require complete neutralisation before lenses contact the eyes.
Before You Decide
Treat the instructions as part of the product.
Skipping steps can undermine the intended cleaning and disinfection process.
Use fresh solution
Do not simply top off old solution in a storage case.
Avoid water exposure
Tap or bottled water is not a contact-lens disinfecting solution.
Know when to stop
Pain, marked redness, discharge or vision changes require lens removal and prompt professional advice.
Contact-lens care has direct eye-safety implications. Always follow lens and solution manufacturer instructions and qualified eye-care advice.
Lens FAQ
Contact Lens Solutions questions
Can contact lens solution be replaced with water?
No. Water is not an appropriate disinfecting or storage substitute for contact-lens care solution.
Can old solution be topped up with fresh solution?
Reuse or topping-off is generally discouraged; follow the specific care-system instructions and use fresh solution as directed.
What is different about hydrogen-peroxide contact-lens solution?
Peroxide systems require a specified neutralisation process before lenses can be placed on the eyes.
Is contact-lens solution the same as rewetting drops?
No. Care solutions and lubricating or rewetting drops serve different purposes.
