Best Practices for Contact Lens Maintenance
Why Proper Contact Lens Care Matters
When you do not care for your contact lenses correctly, you increase your risk of serious eye problems. Bacteria, fungi, and parasites can grow on dirty lenses and cause painful infections that may threaten your vision.
- Corneal ulcers that can permanently scar your eye
- Microbial keratitis requiring intensive treatment
- Allergic reactions to built-up deposits
- Eye inflammation and chronic discomfort
Your contact lens sits directly on the delicate surface of your cornea. When bacteria or other organisms contaminate the lens, they can multiply rapidly in the warm, moist environment between the lens and your eye. These microorganisms may damage the protective outer layer of your cornea, allowing the infection to penetrate deeper tissues.
Contamination often happens through contact with tap water, saliva, or dirty hands. Even a small amount of exposure can introduce harmful organisms that cause serious problems.
Repeated infections or chronic inflammation from poor lens care can have lasting consequences for your eyes. Scar tissue on the cornea may permanently blur your vision, and severe damage might require a corneal transplant in extreme cases.
You may also develop giant papillary conjunctivitis, a condition that makes wearing contact lenses uncomfortable or impossible. Taking care of your lenses properly helps you avoid these long-term complications and continue enjoying clear vision.
Our eye doctors frequently encounter patients who unknowingly practice unsafe lens care habits. Many people do not realize these common mistakes put their eyes at risk.
- Sleeping in lenses not approved for overnight wear
- Using tap water to rinse lenses or cases
- Topping off old solution instead of replacing it completely
- Wearing lenses longer than the prescribed schedule
- Skipping the cleaning step with daily solution
Daily Cleaning and Disinfection Steps
Clean hands are the foundation of safe contact lens care. Always wash your hands with soap and water before touching your lenses, making sure to scrub for at least 20 seconds. Rinse thoroughly to remove all soap residue, which can irritate your eyes if it transfers to your lenses.
Dry your hands completely with a lint-free towel. Water droplets on your fingers can introduce harmful microorganisms to your lenses, and towel fibers can transfer to the lens surface and cause discomfort.
Even if your solution is labeled as a no-rub formula, we recommend gently rubbing your lenses to remove protein deposits and debris. Place the lens in the palm of your clean hand, apply a few drops of fresh solution, and use your index finger to gently rub both sides of the lens for the time recommended on the solution label.
- Apply gentle friction across the lens surface without damaging it
- Rinse the lens thoroughly with fresh solution after rubbing
- Follow your solution's rinsing instructions carefully
- Repeat the process for both lenses every night
We may recommend a specific type of contact lens solution based on your lens material and your eye health needs. Multipurpose solutions work for most soft contact lens wearers, providing cleaning, rinsing, disinfection, and storage in a single product. Some patients with sensitive eyes or allergies need preservative-free hydrogen peroxide systems.
Hydrogen peroxide systems require special handling for your safety. These solutions must be neutralized in the special case provided for the full time specified in the product instructions. Never put hydrogen peroxide solution directly in your eye, and do not rinse lenses with peroxide immediately before insertion unless the solution has been completely neutralized.
Always check that your solution is compatible with your specific lens type. Rigid gas permeable lenses require different solutions than soft lenses, and some specialty lenses have unique care requirements.
Using the wrong products on your contact lenses can damage them or harm your eyes. Tap water contains microorganisms, including a dangerous parasite called Acanthamoeba that causes severe eye infections. Saliva introduces bacteria from your mouth directly to your eye.
- Tap water, distilled water, or bottled water
- Saliva or any bodily fluids
- Homemade saline solutions
- Rewetting drops not designed for lens cleaning
- Expired or contaminated solutions
Always remove your lenses before going to sleep unless you have extended wear lenses specifically approved for overnight use. The following removal method applies to soft contact lenses. Look up and slide the lens down onto the white part of your eye before gently pinching it between your thumb and index finger. This technique prevents tearing the lens or scratching your cornea.
If you wear rigid gas permeable or scleral lenses, follow the specific removal method prescribed by our eye doctor, which may include using a removal tool or specialized technique for your lens type.
Clean each lens immediately after removal while you still remember which eye it came from. Some people have different prescriptions for each eye, and switching lenses can blur your vision and cause discomfort.
Contact lenses are medical devices that must be fitted individually to your eyes. Sharing lenses with another person can transfer harmful bacteria and increase your risk of serious infections. Only use contact lenses that have been properly prescribed and fitted by our eye doctor, including cosmetic or decorative lenses.
- Never share your contact lenses with anyone
- Only use lenses prescribed specifically for your eyes
- Avoid purchasing decorative lenses without a valid prescription and proper fitting
- Stop wearing lenses immediately and contact our office if you experience pain, redness, or vision changes
Storage and Handling Best Practices
Your lens case needs as much care as your lenses themselves. After inserting your lenses each morning, empty all old solution from the case and rinse it with fresh contact lens solution, never tap water. Rub the inside of each case well with clean fingers, then rinse again with fresh solution and place the empty case upside down on a clean tissue to air dry.
Allowing the case to dry completely between uses helps prevent biofilm formation, a slimy layer of bacteria that resists disinfection. Keep your case in a clean, dry location away from the bathroom sink, where water splashes can contaminate it. Avoid letting the tip of your solution bottle touch any surface, including the case or your hands.
We recommend replacing your contact lens case at least every three months, even if it looks clean. Many solution manufacturers include a new case with each bottle, making replacement convenient and affordable.
- Replace your case immediately if it becomes cracked or damaged
- Discard any case that develops a cloudy film or discoloration
- Mark your calendar or set a reminder for quarterly case replacement
- Consider replacing your case after recovering from an eye infection
Water and contact lenses should never meet. Remove your lenses before swimming, showering, or using a hot tub, as all water sources can harbor dangerous microorganisms. If you must swim with your lenses, wear tight-fitting goggles and replace your lenses immediately afterward.
The organisms in water can bind tightly to contact lens materials, making them difficult to remove even with proper disinfection. Avoiding water exposure protects your eyes from infection and keeps your lenses safe.
When traveling, pack enough contact lenses and fresh solution for your entire trip, plus extras in case of delays. Carry your supplies in your carry-on bag so you have access if checked luggage is lost. Small bottles of solution fit easily in your travel kit and can be packed within travel liquid limits.
- Bring a backup pair of glasses in case you need to rest your eyes
- Pack your lens case in a sealed plastic bag to prevent leaks
- Avoid using hotel tap water for any part of your lens care routine
- Keep daily disposables on hand for convenience and hygiene
If you plan to stop wearing your contact lenses for more than a day or two, you cannot simply leave them in the same solution. Replace the solution in your case daily, even when not wearing the lenses, to maintain proper disinfection. Storage guidelines depend on your lens type and replacement schedule, and you should not exceed the total replacement interval even if you are not wearing the lenses every day.
Before reinserting lenses after a prolonged break, disinfect them again according to your solution's instructions. Always check with our eye doctor before taking extended breaks from contact lens wear, as your eyes may need time to readjust when you start wearing lenses again.
- Daily disposables must be discarded after single use and cannot be stored
- Two-week and monthly soft lenses can be stored with daily solution changes but must not exceed their replacement interval from the date you first opened them
- Rigid gas permeable, scleral, and orthokeratology lenses require storage according to your prescribed care system and our office instructions
Following Replacement and Wearing Schedules
Contact lenses are designed for specific wearing periods, whether daily, biweekly, or monthly. Wearing lenses beyond their intended replacement schedule allows protein deposits and microorganisms to build up, increasing your risk of infection and discomfort. Your prescription specifies the replacement schedule that works best for your eye health and lifestyle.
Mark your calendar or use a smartphone app to track when you opened each new pair of lenses. Trying to remember when you started wearing a pair often leads to overwearing them.
Sometimes you need to replace your contact lenses before the scheduled date. A torn lens can scratch your cornea, while a lens with deposits or discoloration may irritate your eyes or blur your vision.
- Any visible tears, chips, or cracks in the lens
- Persistent cloudy spots that do not clear with cleaning
- Lenses that feel uncomfortable even after thorough cleaning
- Discoloration from makeup, medication, or other contaminants
- Lenses that were exposed to tap water or other unsafe substances
Daily disposable lenses offer the most convenient and hygienic option for many contact lens wearers. You wear each lens once and discard it at the end of the day, eliminating the need for cleaning solutions or storage cases. This reduces your risk of infections compared to reusable lenses because you start with a fresh, sterile lens every morning, though you must still avoid water exposure, sleeping in lenses, and handle them with clean hands.
Never try to extend daily disposable lenses to a second day, even if they feel comfortable. These lenses are thinner and more fragile than reusable lenses and are not designed to withstand cleaning or overnight storage.
Some contact lenses are approved for overnight wear, up to the number of nights specified for your exact lens brand and type. Extended wear should only be done if specifically prescribed and monitored by our eye doctor. However, sleeping in contact lenses, even those approved for extended wear, increases your risk of eye infections compared to daily wear. We may recommend removing your lenses nightly even if they are approved for extended wear.
If you do sleep in your extended wear lenses, watch carefully for any signs of redness, discomfort, or vision changes. Remove your lenses immediately if you notice any problems and schedule an appointment with our eye doctor.
Wearing your contact lenses for too many hours each day or too many days without replacement deprives your cornea of oxygen. Your cornea gets oxygen from the air, not from blood vessels, and contact lenses reduce the amount that reaches the eye surface. Chronic oxygen deprivation can cause your cornea to grow abnormal blood vessels as it tries to get more oxygen, a condition called corneal neovascularization.
- Corneal swelling that blurs your vision
- Increased risk of infections due to weakened corneal defenses
- Permanent changes to corneal shape affecting vision quality
- Reduced tolerance for contact lens wear over time
Professional Care and Routine Monitoring
We recommend that contact lens wearers have comprehensive eye exams at least once a year, even if your vision seems stable. These annual visits allow us to monitor your eye health, check how your cornea is responding to lens wear, and update your prescription if needed. Some patients with certain eye conditions or wearing specialty lenses may need more frequent evaluations.
Regular exams catch small problems before they become serious. Your eyes can develop changes that you do not notice until significant damage has occurred, making prevention far better than treatment.
During your contact lens examination, we assess much more than just your vision clarity. We examine the front surface of your eye with specialized instruments to look for signs of inflammation, oxygen deprivation, or early infection. We also evaluate how well your lenses fit and move on your eyes.
- Corneal health and clarity using a slit lamp microscope
- Lens fit, movement, and centration on your eye
- Your tear film quality and contact lens compatibility
- Any deposits or buildup on the lens surface
- Your compliance with care and replacement schedules
Your contact lens prescription might need updating for several reasons beyond changes in your vision. As you age, your eyes produce fewer tears, which might require switching to a different lens material that retains moisture better. If you develop allergies or sensitivity to certain lens care products, we may recommend different lenses or cleaning systems.
New contact lens technologies emerge regularly, offering better oxygen transmission, comfort, or convenience than older options. We stay current on the latest advances in contact lens design and materials to help you achieve the best possible vision and comfort.
We encourage you to bring your contact lens care products to your appointment and describe your daily routine in detail. Being honest about your habits, even if you sometimes take shortcuts, helps us identify risks and provide personalized guidance. We are here to help you protect your eyes, not to judge you.
If you find certain aspects of lens care difficult or confusing, let us know. We can demonstrate proper techniques, recommend easier alternatives, or suggest different lens types that better match your lifestyle and capabilities.
Warning Signs and When to Seek Care
Mild redness after removing your contact lenses that resolves quickly is usually not concerning. However, redness that persists, worsens, or occurs while wearing your lenses signals a problem. Remove your lenses immediately if you notice significant redness and contact our office for guidance.
- Redness accompanied by pain or light sensitivity
- Red eyes upon waking if you slept in your lenses
- Redness that stays or worsens after lens removal
- One eye significantly redder than the other
Your contact lenses should never cause pain. Sharp, stabbing pain might indicate a torn lens or foreign object under the lens, while aching pain could signal an infection or corneal abrasion. Remove your lenses immediately if you experience any pain and examine the lens for damage.
Sudden vision changes, including blurring that does not clear with blinking or seeing halos around lights, require prompt attention. Do not attempt to continue wearing your lenses if your vision changes unexpectedly, even if there is no pain.
Eye infections related to contact lens wear can progress rapidly and threaten your vision if not treated promptly. Familiarize yourself with the warning signs so you can seek care quickly if problems develop.
- Unusual discharge from your eye, especially thick or colored mucus
- Severe light sensitivity that makes you want to close your eyes
- Sensation of something in your eye that persists after lens removal
- Significant swelling of your eyelids or the area around your eye
- Vision loss or severe blurring that does not improve
Certain situations demand that you remove your contact lenses right away to prevent damage to your eyes. If you experience any eye irritation, always remove your lenses first and assess whether symptoms improve. If you cannot easily remove a lens or if it seems stuck to your eye, apply rewetting drops approved for contact lens use and wait a moment before trying again.
Remove your lenses immediately if you get any chemicals or irritants in your eyes, then flush your eyes thoroughly. In the case of chemical exposure, begin flushing immediately with any available clean water or sterile saline. Do not delay irrigation while searching for sterile solution, as this is the critical exception to the general rule about avoiding tap water with contact lenses.
- Start flushing the affected eye immediately with copious amounts of water or saline
- Remove your contact lenses as soon as you can do so easily during or after flushing
- Continue flushing for an extended period following poison control or emergency guidance
- Seek emergency medical care if you experience pain, vision changes, or persistent irritation
- Do not reinsert contact lenses until you have been cleared by a medical professional
Some contact lens problems require same-day or emergency attention, while others can wait for the next available routine appointment. Severe pain, sudden vision loss, or symptoms of infection need urgent evaluation, typically within hours. Contact our office immediately for guidance on whether you need emergency care.
Less urgent issues, such as mild discomfort that resolves with lens removal, persistent dryness, or questions about your care routine, can usually be addressed at a routine appointment. When in doubt, call our office and describe your symptoms so we can advise you on the appropriate timing for care.
Frequently Asked Questions
Never use tap water on your contact lenses or lens case, even if you plan to disinfect them afterward. Tap water contains Acanthamoeba and other organisms that attach to lens materials and resist standard disinfection, potentially causing severe infections that are difficult to treat. Always use fresh contact lens solution for all rinsing and storage.
Sleeping in contact lenses substantially increases your risk of serious eye infections compared to removing them nightly, even if your lenses are approved for extended wear. Most eye care professionals recommend removing all contact lenses before sleep whenever possible to maximize eye health and minimize complication risks.
Most contact lens solutions remain effective for up to three months after opening if you follow proper storage practices and avoid contaminating the bottle tip. Check the expiration date and discard date printed on your solution bottle, and write the opening date on the bottle as a reminder. Never use solution past its discard date, even if the bottle is not empty.
You must never reuse or top off solution in your contact lens case. Used solution loses its disinfecting ability and can become contaminated with microorganisms from your lenses. Always empty your case completely, rinse it with fresh solution, let it air dry, and fill it with fresh solution each time you store your lenses.
Remove the uncomfortable lens and examine it for tears, debris, or inside-out placement, which causes a less comfortable fit. Rinse the lens thoroughly with fresh solution and reinsert it if it appears undamaged. If discomfort continues, discard that lens and use a fresh one, or switch to your backup glasses and contact our office if the problem persists.
Some contact lens solutions are not compatible with certain lens materials and can damage your lenses or fail to disinfect them properly. Consult our eye doctor before changing solution brands to ensure the new product is appropriate for your specific lens type and eye health needs. We can also help if you experience sensitivity to your current solution.
