Contact Lens Solution Mistakes That Irritate Your Eyes

Common contact lens solution mistakes cause redness, burning, and dryness. Learn the causes, fixes, and when to switch products or see an eye doctor.
Quick answer
Most contact lens solution irritation comes from using the wrong solution for your lens type, reusing old solution, or skipping the rub-and-rinse step. Switch to a preservative-free or hydrogen peroxide system if your eyes sting, and always discard solution after each use. If burning continues after two days of correct use, stop wearing lenses and see an eye doctor.
Mistake 1: Using tap water or saliva to rinse lenses
Tap water contains microorganisms that can stick to soft lenses and cause severe eye infections. Saliva introduces bacteria and enzymes that break down the lens surface. Always use a sterile contact lens solution for rinsing, storing, and disinfecting. If you are caught without solution, throw away the lenses rather than risk your eye health.
Mistake 2: Topping off old solution in the case
Adding fresh solution to the old liquid in your case dilutes the disinfectant and leaves behind dead microbes and protein. Empty the case completely, rinse with fresh solution, and let it air-dry face down before refilling. Replace your lens case every one to three months to prevent biofilm buildup.
Mistake 3: Skipping the rub-and-rinse step
Even no-rub solutions work better when you gently rub each lens with solution for five to ten seconds. This physical action removes protein, lipids, and cosmetics that chemical disinfection alone may miss. Rubbing also helps colored contact lenses maintain a smooth surface, reducing the chance of irritation from deposit buildup.
Mistake 4: Using the wrong solution for your lens material
Some multipurpose solutions contain preservatives like polyhexamethylene biguanide (PHMB) that can irritate sensitive eyes. If you wear colored contacts made from hydrogel materials, a preservative-free peroxide system or a solution labeled for sensitive eyes may be gentler. Always check that the solution is approved for soft contact lenses.
Mistake 5: Ignoring expiration dates and storage temperature
Solution loses potency after its expiration date or when stored above 30°C (86°F). Heat and time reduce its ability to disinfect and wet the lens. Store solution airtight at room temperature, and write the discard date on the bottle when you open it. Never use a bottle that has been open for more than three months unless the manufacturer states otherwise.
Mistake 6: Wearing lenses longer than recommended
Even with perfect solution care, wearing lenses beyond their replacement schedule traps irritants against the eye. Daily disposable lenses avoid solution entirely, while monthly lenses require daily cleaning and storage. If your eyes feel dry or gritty by the end of the day, consider a shorter replacement cycle or a lens with higher oxygen permeability.
Is it the solution or something else?
- Symptom: Burning or stinging immediately after inserting lenses: Likely cause: Preservative sensitivity or solution residue on the lens. Corrective action: Rinse lenses with sterile saline or a preservative-free solution before insertion. If burning persists, switch to a hydrogen peroxide system. If burning continues after switching solutions, stop wearing lenses and consult an eye care professional.
- Symptom: Redness and irritation that builds over hours: Likely cause: Poor lens hygiene, such as reusing old solution or not rubbing lenses. Corrective action: Discard current solution, clean case, and start fresh with a rub-and-rinse routine. Replace lenses if they are past their replacement date. If redness does not improve within 24 hours of proper care, remove lenses and see a doctor.
- Symptom: Dry, gritty feeling despite using solution: Likely cause: The solution is not wetting enough for your eyes, or lenses are worn too long. Corrective action: Try a solution labeled for sensitive eyes or add preservative-free rewetting drops. Shorten wearing time and consider daily disposables. If dryness causes pain or blurred vision, stop lens wear and seek professional advice.
Products that support better lens care
- Largo Lens Solution 15mL: Largo Lens Solution 15mL is a clear, colorless liquid for cleaning, disinfecting, rinsing, preserving, wetting, lubricating, and protein removal. It contains polyhexamethylene biguanide hydrochloride solution 20% and phosphoryl choline, and should be stored airtight at room temperature (1–30°C). A 15mL bottle is travel-friendly and covers all daily care steps, but if you are sensitive to PHMB, you may need a preservative-free alternative.
- Toulouse: Toulouse red color contacts are made with 45% pHEMA hydrogel, a soft material, and come in powers from -0.00 to -3.25 (SPH) with a 14.2mm diameter. Soft hydrogel lenses require thorough cleaning to prevent protein buildup, so using the right solution and rub-and-rinse technique is essential for comfortable wear.
