How To Keep Contact Lenses Without Solution: Emergency Storage Solutions And Safety Rules
Running out of contact lens solution is a high-risk scenario that requires immediate, sterile handling to prevent microbial keratitis and permanent corneal damage. While makeshift liquids can keep lenses hydrated temporarily, using water, saliva, or unapproved homemade saline introduces severe infectious agents like Acanthamoeba straight to your eye surface.
Emergency Preparedness and Contamination Risks
Encountering a shortage of multipurpose contact lens solution demands a strict evaluation of risks versus alternatives. Soft contact lenses are porous hydrogel or silicone hydrogel matrices designed to absorb and retain moisture, making them prone to trapping pathogens when exposed to non-sterile environments.
- Essential Gear and Materials: Clean storage case, fresh daily-use saline (if available), bottled or distilled water (as an absolute last resort), and a clean lens removal tool or thoroughly washed hands.
- Mandatory Prerequisite Knowledge: Standard tap water contains microorganisms that thrive on contact lens surfaces, leading to vision-threatening corneal ulcers. Never submerge lenses in tap water or store them dry, as dehydration alters lens parameters and tears the material.
- Time and Safety Benchmarks: Temporary storage should never exceed 4 to 6 hours before discarding the lenses entirely. If you experience redness, photophobia, or blurred vision upon reinsertion, remove the lenses immediately and switch to backup eyeglasses.
Step-by-Step Emergency Lens Storage Workflow
Step 1: Meticulous Hand Hygiene and Preparation
Before touching your eyes, lenses, or any makeshift storage container, perform a rigorous hand-washing protocol using antibacterial soap and warm water for at least 20 seconds. Dry your hands thoroughly with a lint-free microfiber towel or allow them to air-dry to prevent transferring cloth fibers to your lenses. Inspect your contact lens case to ensure it is completely clean; if possible, rinse the wells with sterile saline or boiling water that has been cooled to room temperature.
Warning: Never use household tap water to rinse your contact lens case or your lenses, as municipal water supplies harbor dangerous amoebas and bacteria that adhere rapidly to lens polymers.
Step 2: Selecting and Evaluating the Temporary Liquid Medium
If you lack multipurpose solution, your choice of temporary liquid is critical for preserving lens integrity without causing chemical toxicity or microbial infection. Preserved, sterile saline solution for sensitive eyes or eye drops labeled safe for contact lenses can serve as a short-term holding liquid. However, sterile saline lacks disinfecting agents, meaning it only keeps the lens hydrated and does not kill bacteria.
Pro-Tip: If you have absolutely no sterile products available, creating a homemade saline solution by boiling water and table salt is an emergency option, but it must cool completely and be used with extreme caution due to the lack of precise chemical balancing.
Step 3: Submerging and Sealing the Lenses
Place each contact lens into its respective right or left well of the storage case, ensuring the lens curves upward and does not fold over on itself. Fill the well completely with your chosen temporary sterile liquid until the lens is fully submerged and floating. Seal the case tightly to prevent air exposure, which causes evaporation and cements the lens to the plastic walls of the container.
Step 4: Rehydration and Mandatory Disinfection Protocol
After retrieving your lenses from temporary storage, you cannot insert them directly into your eyes without a deep-cleaning cycle. Transfer the lenses into a case filled with fresh, high-quality multipurpose disinfecting solution and allow them to soak for the full disinfection time recommended by the manufacturer, typically 4 to 6 hours. This step helps neutralize microbial growth picked up during the emergency storage phase.

Comparison of Emergency Storage Media and Safety Ratings
| Storage Medium | Sterility Level | Disinfection Capability | Risk Level | Maximum Recommended Duration |
|---|---|---|---|---|
| Multipurpose Solution | Sterile | High | None | Up to 30 Days (in closed case) |
| Preserved Sterile Saline | Sterile | None | Low | 4 to 6 Hours |
| Homemade Salt Solution | Non-Sterile | None | High | 2 Hours Maximum |
| Bottled/Distilled Water | Non-Sterile | None | Very High | Immediate Disposal Recommended |
| Tap Water or Saliva | Contaminated | None | Extreme | Do Not Use |
Common Site Failures and Field Fixes
- Lens Adhered to the Case Walls:
- Root Cause: The temporary liquid evaporated completely, causing the soft hydrogel material to dry out and stick to the plastic.
- Actionable Fix: Fill the case generously with fresh multipurpose solution or sterile saline and let it sit undisturbed for 15 to 30 minutes. Gently tease the edges free with a clean fingertip once the polymer rehydrates; never pull or tear a dry lens.
- Severe Eye Irritation Upon Reinsertion:
- Root Cause: Pathogen contamination or chemical toxicity from an improper temporary liquid during the storage window.
- Actionable Fix: Remove the contact lens immediately, flush your eye with sterile eye drops or saline, and switch to wearing prescription eyeglasses until an optometrist evaluates your eye health.
- Deformed or Torn Lens Edges:
- Root Cause: Mechanical stress while handling a partially dehydrated lens that lacked structural flexibility.
- Actionable Fix: Discard the damaged lens immediately. Attempting to wear a compromised lens can scratch the corneal epithelium and cause abrasions.
Frequently Asked Questions
Can I use tap water to store my contact lenses overnight?
No, tap water must never be used to store, rinse, or clean contact lenses under any circumstances. Tap water contains microorganisms such as Acanthamoeba, which can cause severe, sight-threatening corneal infections that are exceptionally difficult to treat.
Is it safe to keep contact lenses in eye drops?
Only specific lubricating eye drops that are explicitly labeled as safe for contact lenses should be used for temporary hydration. Standard redness-relieving eye drops contain vasoconstrictors and preservatives that can bind to the lens material and cause toxic chemical reactions on the surface of your eye.
What should I do if I have no solution and cannot find an open store?
Your safest course of action is to remove your contact lenses, discard them if they have been compromised by unsafe liquids, and wear your backup eyeglasses. Sleeping in lenses stored in unapproved liquids exponentially increases your risk of developing a serious eye infection.
How long can contact lenses survive in pure sterile saline?
Sterile saline can keep contact lenses hydrated for a few hours, but because it contains no disinfecting chemicals, bacteria can still multiply in the liquid. You must disinfect the lenses in a multipurpose or hydrogen peroxide solution before placing them back on your eyes.
Secure your vision health today by keeping an emergency travel-sized bottle of contact lens solution in your car, office, or bag to avoid dangerous improvised storage situations.
