Practical guidance on cleaning, storage, and wearing schedules that reduce the risk of eye infections from contact lens use.

Key Takeaways

Always wash and dry your hands thoroughly before handling contact lenses.
Never rinse lenses or cases with tap water — use only sterile contact lens solution.
Replace your lens case at least every three months to prevent bacterial buildup.
Remove lenses before swimming, showering, or sleeping unless prescribed for extended wear.
Follow your prescribed replacement schedule and attend annual eye exams.

Why Lens Hygiene Matters More Than Most Wearers Realize

Approximately 45 million Americans wear contact lenses, and the freedom they offer is real — but so is the risk when care routines slip. Contact lenses sit directly on the cornea, the eye's transparent outer surface, creating a potential pathway for bacteria, fungi, and parasites to cause infection. The good news: the large majority of contact lens-related eye problems are preventable with consistent habits.

If you are still weighing whether contacts are right for you, see our comparison of glasses and contact lenses to understand how each option fits different lifestyles. And if you are new to contacts, preparing for your first fitting covers the baseline habits to establish from day one.

According to CDC estimates, roughly one million Americans seek medical care for contact lens complications each year.

Of contact lens wearers who report at least one risky behavior

A CDC survey found that nearly all contact lens wearers acknowledge habits — such as sleeping in lenses or topping off solution — that increase infection risk.

Core Practices for Safe Contact Lens Care

The following evidence-based practices are recommended by optometric and public health authorities to minimize your risk of infection and keep your corneas healthy over the long term. Consistency matters — a single lapse in hygiene on the wrong day can be enough to introduce a harmful pathogen.

Daily Disposables Are Different

If your eye care provider has prescribed daily disposable lenses, you discard them each night — no cleaning or storage solution is needed. Never attempt to rewear daily disposables, as their thin material and lack of UV protection coatings make reuse unsafe. Confirm your lens type with your provider if you are unsure.

Wash and thoroughly dry your hands before every lens insertion and removal.

Hands carry bacteria, viruses, and environmental debris that transfer directly to lenses and then to your cornea. Drying is equally critical — residual water harbors Acanthamoeba, an organism linked to a serious corneal infection called Acanthamoeba keratitis.

Example: Use soap and a lint-free paper towel rather than a cloth towel, which can harbor microorganisms even after laundering.

Use fresh, sterile contact lens solution every time you store your lenses — never top off old solution.

Topping off reuses solution that has already been exposed to air and lens deposits, dramatically reducing its disinfecting effectiveness. The CDC has identified this habit as a key contributor to preventable eye infections.

Example: Empty the case completely, rub the lens gently with fresh solution before storing it, then fill the case with new solution before placing the lens inside.

Rub and rinse your lenses with solution even if the packaging says 'no-rub.'

Studies have shown that mechanical rubbing removes more microbial deposits than rinsing alone, regardless of solution labeling. The American Optometric Association supports rubbing as the preferred technique for thorough cleaning.

Example: Place the lens in your palm, add a few drops of solution, and rub gently in a circular motion for 20 seconds before rinsing.

Replace your lens storage case at least every three months.

Biofilm — a thin layer of microorganisms — accumulates inside cases over time and resists routine rinsing. A contaminated case can re-infect freshly cleaned lenses immediately.

Example: Many lens solution bottles include a free case in the box; use each new bottle as a reminder to swap out your case.

Never wear contact lenses while swimming, in the shower, or in a hot tub.

Tap water, pools, lakes, and hot tubs all contain microorganisms — including Acanthamoeba — that can adhere to lenses and cause sight-threatening infections. Even brief exposure carries real risk.

Example: Keep a pair of prescription swim goggles available if vision correction is needed in the water.

Adhere strictly to the replacement schedule prescribed by your eye care provider.

Overwearing disposable lenses allows protein and lipid deposits to accumulate, reducing oxygen flow to the cornea and increasing infection risk. The schedule is based on the specific material and coating of your lens type.

Example: Set a recurring reminder on your phone aligned to your two-week or monthly replacement cycle so the swap is never delayed.

Warning Signs and When to Seek Care

Good hygiene significantly reduces risk, but it does not eliminate it entirely. Knowing the early warning signs of a contact lens complication is just as important as cleaning technique.

When to Remove Lenses Immediately

If you experience sudden redness, pain, unusual discharge, blurred vision, or increased light sensitivity while wearing contact lenses, remove them right away and contact your eye care provider promptly. Do not insert a new pair until you have been evaluated. These symptoms may signal an early infection that is far easier to treat when caught quickly.

Prompt evaluation is essential because some infections — particularly bacterial keratitis — can progress rapidly. Never attempt to self-treat eye infections with over-the-counter drops without professional guidance.

Annual comprehensive eye exams give your provider the opportunity to detect subclinical changes in corneal health before symptoms appear. Learn more about building a prevention-focused routine at our eye exam and prevention hub.

Start Today: Quick Wins for Safer Lens Wear

You do not need to overhaul every habit at once. A few targeted changes can meaningfully reduce your risk starting today. For context on how different lens materials and replacement schedules affect your care routine, see our overview of contact lens types.

high Check your lens case right now — if it is cracked, discolored, or older than three months, replace it today.

high Pour out any leftover solution in your lens case tonight and refill with fresh solution before storing your lenses.

medium Set a phone reminder for your next scheduled lens replacement so you never accidentally overwear a pair.

low Move your contact lens solution away from the bathroom sink to reduce accidental water splashing into an open bottle.
