Why Is Proper Lens Storage Such a Big Deal?
Contact lenses sit directly on the cornea, one of the most sensitive and vulnerable parts of the body. Improper hygiene can lead to serious eye infections, vision loss, and even blindness. According to the American Academy of Ophthalmology, about 1 in 5 contact lens wearers will experience a complication related to poor hygiene. This isn’t just about comfort—daily lens care is a critical part of eye health.
Is Your Lens Case as Clean as It Should Be?
Even if you clean your lenses regularly, a dirty case can nullify your efforts. The lens case is often the primary source of microbial contamination. Follow these essential steps:
- Rinse the case daily with multipurpose solution (never water) and let it air dry completely
- Replace the case at least once a month
- Keep the case open when drying—closing it while wet traps bacteria and moisture
Cases that are moist or used for too long become breeding grounds for fungi, bacteria, and biofilms. Avoid rinsing with tap water as it can introduce dangerous microbes.
Can You Use Water or Saline Instead of Lens Solution?
Absolutely not. Tap water, bottled water, and saline solution lack antimicrobial agents and can expose your eyes to pathogens like Acanthamoeba. These microorganisms are resistant to standard cleaning and can cause painful infections. Only use disinfecting lens solutions specifically formulated for soft or rigid gas permeable lenses.
Are You Really Washing Your Hands the Right Way?
Hand hygiene is a non-negotiable step before touching lenses. Here’s how to do it properly:
- Wash hands with fragrance-free soap for at least 30 seconds
- Dry with a lint-free towel or paper towel, avoiding shared cloth towels
- Avoid using lotions or oils immediately before handling lenses
Invisible residue like oils or particles can easily stick to lenses, increasing the risk of irritation and infection. This simple step is often the first point of failure for many users.
Are You Skipping the “Rub and Rinse” Method?
Placing lenses in solution is not enough. The “rub and rinse” method dramatically improves cleanliness:
- Place the lens in the palm of your hand
- Apply a few drops of solution and gently rub with a fingertip in a circular motion
- Rinse again with fresh solution before storing
This process removes protein buildup, oil, and environmental particles. Clinical studies show this technique reduces microbial contamination by up to 80%.
Are Daily Disposables Safer Than Monthly Lenses?
In many cases, yes. Daily disposable lenses eliminate the need for cleaning or storage, reducing the risk of contamination. Monthly or bi-weekly lenses require strict adherence to hygiene protocols, and failure to maintain cleanliness can lead to cumulative damage. If your routine is inconsistent, switching to daily lenses may be the safer option despite higher cost.
Is It Safe to Use Makeup or Spray Near Your Lenses?
Makeup particles and aerosol sprays can severely compromise lens hygiene.
- Avoid using spray products like hairspray or perfume after putting in lenses
- Use non-oily, ophthalmologist-approved eye makeup
- Apply makeup after inserting lenses and remove lenses before removing makeup
These precautions help prevent film buildup on lenses and irritation that can result from makeup particles being trapped between the lens and cornea.
Should You Ever Store Contact Lenses in the Fridge?
No. Storing lenses or solution in the refrigerator is a common myth and a dangerous one.
- Low temperatures can alter the chemical structure of lens solutions, reducing their effectiveness
- Chilled lenses may warp or become uncomfortable
- Condensation can introduce bacteria when brought back to room temperature
Always store lenses and solution in a cool, dry, and room-temperature environment, away from direct sunlight and humidity.
What Are the Warning Signs of Lens Contamination?
If you notice any of the following, discontinue use immediately:
- Lenses appear cloudy, discolored, or sticky
- Solution appears cloudy or has floating debris
- Symptoms like redness, excessive tearing, pain, or light sensitivity after insertion
These signs could indicate fungal or bacterial contamination, and continuing to wear affected lenses could cause corneal ulcers or long-term damage.
How Should You Store Lenses When Traveling?
Traveling introduces new variables that can compromise hygiene. Here’s how to stay safe:
- Use a travel-sized sterile lens kit with backup lenses, solution, and a mirror
- Carry daily disposables to simplify care during long trips
- Store everything in a temperature-stable, dry area
On airplanes, the dry cabin air and pressure changes can increase lens discomfort. Consider not wearing lenses during flights or use single-use dailies.
Quick Recap: Your Daily Checklist for Safe Contact Lens Use
To ensure long-term eye health while using contact lenses, commit to the following:
- Clean hands before touching lenses—every time
- Rub and rinse lenses daily, never skip the cleaning step
- Replace your lens case monthly and let it dry between uses
- Avoid water, sprays, and cold storage
When in doubt, throw it out—it’s better to lose a lens than damage your vision. Consistent hygiene is the single best way to protect your eyes.
