Contact Lens Solution: Types, Cleaning and Safe Storage
If you wear reusable contacts, the bottle beside your lens case is part of the care system. The useful question is not simply “Do I have contact lens solution?” but what job does that solution actually perform? Some products clean, rinse, disinfect and store compatible lenses. Saline does not replace disinfection, and hydrogen peroxide systems follow a different process altogether.
Quick answer
Reusable contact lenses need the care system specified for that lens and product. Multipurpose solution can clean, rinse, disinfect and store compatible soft lenses. Saline does not disinfect contact lenses. Hydrogen peroxide systems require their dedicated case and full neutralisation process. Never replace an approved care system with water, saliva or a homemade mixture.
What is contact lens solution, and when do you need it?
Contact lens care solutions are used with lenses that need cleaning, disinfection or storage between wears. That mainly matters for reusable lenses.
A genuine daily disposable follows a different routine. You wear it according to its instructions, remove it and discard it rather than cleaning it for storage and wearing it again the next day.
For example, DAILIES TOTAL1 is currently listed by LensCode with a daily usage schedule. A reusable option such as Amara Espresso is listed as monthly, so its after-wear care workflow is different.
Choose the lens first, then its care routine
Compare the replacement schedule and product information before deciding what cleaning and storage system is required.
Browse Contact LensesAre all contact lens solutions the same?
No. Products used around contact lenses can perform very different jobs.
| Type | Cleaning | Disinfection | Rinsing | Storage | Main point |
|---|---|---|---|---|---|
| Multipurpose solution | Yes, for compatible lenses | Yes | Yes | Yes | Follow the exact product directions and lens compatibility. |
| Saline | Not a complete cleaning system | No | May be used for rinsing in some care systems | Not a substitute for disinfecting solution | Saline does not disinfect contacts. |
| Hydrogen peroxide-based system | According to the system | Yes | Follow product directions | Uses its dedicated case | Requires complete neutralisation before the lenses are worn. |
Rigid gas-permeable lenses may use a different care system from soft lenses. Do not move a solution from one lens routine to another simply because both products say “contact lens” on the packaging.
How do you choose the right contact lens solution?
There is no universal “best contact lens solution” for every wearer and every lens. The useful choice is the system that matches the lens type, the manufacturer's directions and any care instructions provided for your lenses.
How should reusable contact lenses be cleaned and stored?
- Wash your hands with soap and water, then dry them completely before handling the lenses.
- Use the care solution specified for the lens and system.
- Rub and rinse the lenses when the care-system instructions direct you to do so.
- Place the lenses in the correct case with fresh disinfecting solution.
- Leave the lenses for the full disinfection or neutralisation period stated by the product.
Do not assume that every bottle has the same soaking time. Multipurpose products and peroxide systems have their own instructions, and the label is the operational reference.
What does “topping off” contact lens solution mean?
Topping off means leaving used solution in the lens case and pouring fresh solution on top of it.
Do not use that as your storage routine. Empty the old solution and use fresh disinfecting solution for the next care cycle.
Can you rinse contacts or the lens case with water?
No. Water is not contact lens disinfecting solution.
Saudi health guidance advises against using tap water to rinse or store contact lenses, and official care guidance also recommends keeping water away from reusable lens cases. Use the appropriate lens-care product instead.
Does saline solution disinfect contact lenses?
No. Saline solution does not disinfect contact lenses.
Saline can have a rinsing role in some care systems, but that is different from killing microorganisms as part of a disinfection process. If your reusable lenses require disinfection before storage, saline alone is not the complete care system.
What can you use if you run out of contact lens solution?
Do not replace contact lens solution with a homemade liquid.
Avoid tap water, bottled water, distilled water, boiled water, saliva, homemade saline, salt-and-water mixtures or household hydrogen peroxide.
Use an appropriate compatible care product for your lens. If a safe cleaning and storage method is not available, do not reinsert a reusable lens as though it has completed the required disinfection cycle.
How should you clean a contact lens case?
The case is part of the care routine, not just a container.
- ✓ Empty the used solution after removing the lenses.
- ✓ Rub and rinse the case with fresh contact lens solution.
- ✓ Do not rinse the case with water.
- ✓ Allow it to air-dry as directed, preferably upside down with the caps off.
- ✓ Replace the case regularly; current CDC guidance says at least every three months.
When should contact lens solution be replaced or discarded?
Check the printed expiry date first, then look for any product-specific discard-after-opening instruction.
Do not create one universal open-bottle rule for every solution. Follow the timing printed for that product, keep the bottle in its original container, and avoid touching or contaminating the dispensing tip.
Do daily disposable contacts need cleaning solution?
Genuine daily disposable contacts do not go through a cleaning and storage cycle for reuse. They are discarded after their intended single-use period.
If that workflow suits how you prefer to manage your lenses, you can compare current corrective contact lenses and look for products whose listed usage schedule is daily.
LensCode contacts and care-system considerations
LensCode's current Contact Lenses collection includes daily and reusable products as well as separate Corrective and Color Contact Lens routes.
Current Linas listings also state “Two lenses + free solution.” You can review the Linas collection for the current range.
The listing confirms that a solution is included, but it does not identify the formulation, volume or care-system type in the product information verified for this guide. Read the actual bottle label and instructions before using the included solution.
7 common contact-lens solution mistakes
- Rinsing or storing lenses in water.

- Topping off fresh solution over old used solution.
- Treating saline as a disinfecting solution.
- Using a peroxide system without its dedicated case and full neutralisation process.
- Ignoring lens-case cleaning and replacement.
- Using expired solution or ignoring product-specific after-opening instructions.
A 30-second contact lens care decision
Start with the lens and its replacement schedule
Then follow the care system specified for the product rather than building a routine around whatever liquid is available.

What is the best contact lens solution?
There is no single solution that is right for every lens. Use a care system compatible with your lens type and follow its product and professional instructions.

No. Water is not a contact lens disinfecting or storage solution.
What can I use instead of contact lens solution?
Do not use water, saliva or homemade saline. Use an approved compatible care product for your lens and follow its instructions.
Does saline disinfect contact lenses?
No. Saline can be used for rinsing in some systems, but it does not disinfect contact lenses.
Can I add new solution to old solution?
No. This is called topping off. Discard the used solution and start the next storage or disinfection cycle with fresh solution.
Do daily contacts need cleaning solution?
Daily disposable lenses are discarded after their intended single use and are not cleaned and stored for another day.
How often should I replace my contact lens case?
Current CDC guidance recommends replacing the case at least once every three months, alongside proper cleaning and drying between uses.
