Why Nightly Removal and Proper Storage Matter
Your cornea needs oxygen to stay healthy, and contact lenses reduce the amount that reaches your eye. When you close your eyelids to sleep, oxygen flow drops even further. This combination can stress the cornea and create an environment where harmful bacteria thrive.
Even a short nap in your lenses can cause problems. Your eyes produce fewer tears during sleep, so lenses dry out and stick to the cornea, making them harder to remove safely when you wake up.
Most soft contact lenses available in 2025 are designed for daily wear only. Sleeping in these lenses increases your risk of serious eye infections by about 5 to 8 times, depending on lens type and individual factors. The lack of oxygen and tear flow creates ideal conditions for bacteria to multiply rapidly.
- Corneal swelling and clouding that affects vision
- Increased risk of microbial keratitis, a vision-threatening infection
- Corneal blood vessel growth that may threaten vision if severe
- Higher chance of painful corneal abrasions
If your lenses are specifically FDA approved and prescribed for extended wear, follow your clinician's schedule and hygiene instructions exactly.
Contact lens cases can become breeding grounds for dangerous microorganisms if not cleaned properly. Bacteria, fungi, and parasites like Acanthamoeba can survive in old solution and contaminated cases. When you place your lenses back in your eyes, these organisms can cause devastating infections.
We see preventable infections regularly in our practice. Simple storage mistakes, like topping off old solution instead of replacing it completely, can lead to weeks of treatment and permanent vision loss in severe cases.
Water increases your risk of serious infection. Avoid contact lenses in showers, swimming pools, lakes, and hot tubs. If lenses are exposed to water, remove and discard them.
- Do not shower or swim while wearing contact lenses
- Use well-fitted swim goggles if water exposure is unavoidable, and wear daily disposables you discard afterward
- Never rinse lenses or cases with tap water
Years of cutting corners with lens care add up. Chronic low-level irritation can cause your cornea to develop tiny scars that blur your vision. Repeated infections may eventually prevent you from wearing contact lenses at all.
- Permanent corneal scarring that requires specialized treatment
- Chronic dry eye that can persist even after you stop wearing lenses
- Contact lens intolerance that limits your vision correction options
- Giant papillary conjunctivitis that makes lens wear uncomfortable
Step-by-Step Contact Lens Removal
Clean hands are your first defense against eye infections. Wash with plain soap and warm water for at least 20 seconds, scrubbing between your fingers and under your nails. Rinse thoroughly to remove all soap residue. Use oil-free, fragrance-free soap and avoid lotions before handling lenses.
Dry your hands with a clean, lint-free towel. Paper towels work well because they do not leave fibers behind. If you must handle lenses near a sink, cover or plug the drain. Avoid using hand sanitizer alone, as it does not remove oils and debris that can transfer to your lenses.
Look up and use your non-dominant hand to hold your upper eyelid open. With your dominant hand, place your index finger on the lower edge of the lens and slide it down slightly onto the white of your eye. Gently pinch the lens between your thumb and index finger and lift it away from your eye.
- Keep your fingernails trimmed short to avoid scratching your cornea
- Move slowly and gently to prevent tearing the lens
- If the lens folds, let it unfold in your palm before storing
- Repeat the same careful process for your other eye
RGP lenses require a different technique than soft lenses. Place one finger at the outer corner of your eye and pull your eyelid slightly toward your ear while blinking. The lens should pop out onto your other hand or a clean towel placed below your face.
Some people use a small suction cup tool designed for RGP removal. We can show you how to use this device safely during your fitting appointment if you find the blink method difficult. Perform removal over a clean towel or with the sink drain plugged to avoid losing the lens. If you use a suction cup remover, clean it with mild soap and water after use and allow it to air dry.
Never force a lens off your eye. First, apply several drops of preservative-free rewetting drops or saline solution to lubricate your eye. Wait a minute, then blink several times and try gentle removal again.
- Close your eyes and gently massage your eyelid to help the lens move
- Look in different directions to shift the lens position
- Add more lubricating drops if needed
- Do not use tweezers or other tools on your eye
- Stop and call sooner if you develop pain, light sensitivity, or decreased vision
- Call our office if the lens remains stuck after 15 minutes of trying
Place each lens in your palm and inspect it under good light before putting it in the case. Look for tears, splits, or rough edges that could scratch your eye. Check that the lens is right-side out, not inverted.
Damaged lenses should be thrown away immediately and replaced with your backup pair. Never wear a torn or damaged lens, even if it seems like a small problem. We can provide replacement lenses during your next visit or through your lens supplier.
Proper Contact Lens Storage Techniques
Use the solution type your eye care professional prescribes. Multipurpose solutions can clean, disinfect, and store lenses in one system, while some lenses are best cared for with hydrogen peroxide systems or other specialty products.
Never use water, saliva, or homemade saline to store your lenses. These alternatives do not disinfect properly and can introduce dangerous organisms. Always use fresh solution from an unopened, unexpired bottle.
Hydrogen peroxide systems require the special case with a neutralizing disc that comes with the product. Never put unneutralized peroxide directly in your eye and never use a regular flat case with peroxide. Allow the full neutralization time listed on the bottle before wearing your lenses.
- Do not mix different solutions in the same case and do not switch systems without instructions from your eye care professional
- Keep the bottle tip sterile by avoiding contact with your fingers, lenses, or case, and recap promptly
- Discard solution bottles by the manufacturer's discard-after-opening date (often 90 days)
- If you wear scleral or orthokeratology lenses, follow the care system prescribed for those lenses rather than the general guidance on this page
After you insert your lenses each morning, empty the used solution from your case immediately. Rinse the case with fresh multipurpose solution, never tap water. Do not use soap or water. Wipe the inside with a clean finger to remove any biofilm or residue.
- After rinsing, shake out excess and turn the case upside down on a clean tissue to air dry, with caps off
- Store the dry case away from the bathroom sink and toilet area, in a clean, dust-free location
- Never leave old solution sitting in the case during the day
- Wash your case with solution at least once daily
- Do not share your lens case or solution bottles
Before placing lenses in the case, clean each lens as directed on your solution bottle.
- Place the lens in a clean, dry palm and add several drops of your multipurpose solution
- Gently rub both sides with a fingertip for 10 to 20 seconds (follow your bottle's instructions)
- Rinse both sides thoroughly with fresh solution
- If you use a hydrogen peroxide system, place lenses in the provided baskets and fill the special case to the line with peroxide; allow full neutralization (at least 6 hours) before wear
- Never put unneutralized peroxide directly in your eye
After rubbing and rinsing each lens, place it in the correct side of your case, right lens in the right compartment and left in the left. Fill each chamber completely with fresh solution until the lens is fully submerged. Seal the case tightly to prevent evaporation and contamination.
Make sure your lenses soak for at least the minimum time listed on your solution bottle. Required times vary by product. This disinfection time kills harmful microorganisms and keeps your lenses safe to wear.
Replace your contact lens case at least every three months, even if it looks clean. Microscopic scratches and biofilm build up over time, creating hiding spots for bacteria that resist normal cleaning. Most solution manufacturers include a free case with each bottle.
- Replace your case immediately if you develop any eye infection
- Get a new case if yours cracks, warps, or will not close properly
- Mark your calendar or set a phone reminder to replace regularly
- Keep a spare case in your travel bag for emergencies
Contact Lens Replacement Guidelines
If you wear daily disposable lenses, you do not need a case or solution at all. Simply remove each lens at night and throw it away. This option eliminates most storage-related risks and offers the healthiest wearing schedule for many patients.
Daily disposables cost more upfront but save money on solution and cases. More importantly, they significantly reduce your infection risk. We may recommend switching to dailies if you struggle with proper lens care or have a history of infections.
Replace lenses on the schedule prescribed for your lens type, regardless of how many days you wore them.
- Daily disposables are single use and must be discarded each day
- Two-week and monthly lenses should not be stretched beyond their replacement interval
- Replace lenses sooner if they feel uncomfortable or show deposits or damage
- Do not extend wear by resting lenses in solution beyond the labeled replacement period
Recognizing Problems from Improper Lens Care
Some mild redness when you first remove your lenses is normal, especially after a long day. However, persistent redness that lasts more than 30 minutes may signal a problem. Your eyes might be reacting to solution ingredients, protein buildup, or early infection.
Consider switching to a different disinfection system, such as a hydrogen peroxide-based system, or to a multipurpose solution with a different preservative. If redness continues for more than a day or two, schedule an appointment with our office so we can check for underlying issues that require treatment.
Your vision should return to normal within a few minutes of removing your contacts. Blurriness that persists suggests corneal swelling, deposits on your lenses, or an incorrect prescription. Chronic overnight corneal swelling from poor lens hygiene can take hours to resolve each morning.
- Corneal edema from oxygen deprivation during extended wear
- Protein or lipid deposits that have built up on the lens surface
- Early signs of contact lens-related dry eye
- Changes in your vision that require a new prescription
Fresh contact lens solution should be clear and colorless. Cloudy, discolored, or stringy solution indicates contamination. This can happen if you touch the bottle tip to your hands, lenses, or case, introducing bacteria or fungi into the bottle.
Throw away contaminated solution immediately and do not use it to store your lenses. Replace your lens case and use a new, unopened bottle of solution. If you already stored lenses in contaminated solution, discard those lenses and start with a fresh pair.
- Do not share solution bottles
- Discard any bottle that is past the manufacturer's discard-after-opening date
- If the bottle tip touches your fingers, lenses, eye, or case, treat it as contaminated and replace the bottle
A cloudy film or white spots on your lenses comes from protein deposits that build up from your tears. Regular cleaning usually prevents this, but some people produce more protein than others. Deposits make your lenses uncomfortable and can harbor bacteria.
- Increase your rubbing and rinsing time when cleaning lenses
- Consider enzyme tablets for weekly deep cleaning if appropriate for your lens type, but do not use enzymatic cleaners with daily disposable lenses
- Replace your lenses more frequently than the maximum wearing schedule
- Ask us about lens materials that resist protein buildup
- Consider switching to daily disposable lenses if deposits recur despite proper cleaning
During your regular contact lens checkup, we examine your cornea, conjunctiva, and eyelids for signs of problems. We look for tiny blood vessels growing into the cornea, areas of thinning or scarring, and inflammation that suggests poor lens care.
We also inspect your contact lenses under magnification to assess deposits, damage, and fit. Bringing your current lenses and your lens case to appointments helps us identify storage problems. These exams catch issues early, before they threaten your vision or ability to wear contacts.
Troubleshooting Common Removal and Storage Problems
Lenses often become dry and sticky after many hours of wear. If removal is difficult, stop and rehydrate your eyes first. Use preservative-free artificial tears or rewetting drops designed for contact lens wearers, wait a few minutes, and try again.
- Take breaks during the day to blink fully and let your eyes rest
- Use rewetting drops throughout the day to prevent excessive drying
- Reduce your wearing time if lenses consistently feel dry
- Try a different lens material that retains moisture better
If your lenses are dry or stuck to the case in the morning, your case may not be sealing properly or you are not using enough solution. Check that the caps twist on tightly and that you fill each chamber to the top. Damaged cases lose solution through evaporation.
Some older cases warp over time and no longer create an airtight seal. Replace your case if you notice this problem repeatedly. Never try to rehydrate dried lenses by adding more solution; throw them away and use a fresh pair.
Do not sleep in your lenses. If you do not have disinfecting solution, the safest choice is to discard your current lenses and wear backup glasses.
If you have sterile, preservative-free contact lens saline, you may temporarily store lenses for a few hours only, then perform a full clean and disinfect cycle with fresh solution before wearing. Do not wear lenses straight from saline. Keep spare solution and a backup case at home and when traveling.
Pack travel-size solution bottles in your carry-on bag, following current liquid restrictions for air travel. Consider bringing daily disposable lenses for your trip to eliminate the need for solution and cases altogether. This simplifies your routine and reduces your infection risk.
- Bring more lenses than you think you will need in case you need to discard a pair
- Pack a new lens case specifically for travel
- Research where to buy replacement supplies at your destination
- Keep backup glasses with you in case you cannot wear your contacts
Arthritis, tremors, or limited finger mobility can make lens removal difficult. We may recommend adaptive tools like soft-tipped lens removers or suction devices designed for people with limited dexterity. These tools are safe when used correctly and can restore your independence.
Daily disposable lenses are often the best choice if you have dexterity challenges. They eliminate the need for case cleaning and reduce the number of steps in your routine. We can work with you to find lenses and techniques that match your abilities.
When to Seek Urgent Care for Contact Lens Problems
Intense pain that does not improve within a few minutes of removing your lens requires immediate attention. This can indicate a corneal abrasion, ulcer, or serious infection. Remove your lenses immediately and do not reinsert them.
Call our office right away or go to an emergency eye care center if we are not available. Severe pain accompanied by light sensitivity, discharge, or redness suggests a condition that can worsen rapidly without treatment.
Any sudden decrease in vision, blind spots, or dramatic blurring while wearing contacts is an emergency. These symptoms can indicate corneal infection, ulcer, or other serious problems that threaten permanent vision loss. Do not wait to see if symptoms improve on their own.
- Remove your lenses immediately and do not put them back in
- Avoid rubbing your eyes, which can worsen damage
- Contact our office for same-day evaluation
- Seek emergency care if you cannot reach us within a few hours
A corneal abrasion is a scratch on your cornea, while an ulcer is an open sore that can become infected. Both cause severe pain, tearing, light sensitivity, and a feeling that something is stuck in your eye. Your eye may be very red and you may have trouble keeping it open.
These injuries can happen if you remove a dry lens too forcefully, sleep in lenses not designed for overnight wear, or wear damaged lenses. We need to examine you promptly to prevent infection and scarring. Treatment often includes prescribed antimicrobial drops and temporary discontinuation of lens wear.
Microbial keratitis is a serious infection of the cornea that requires aggressive treatment. Warning signs include severe eye pain, extreme light sensitivity, heavy discharge, very red eyes, and vision loss. You may also notice a white spot on your cornea.
Contact lens-related infections can progress rapidly, sometimes causing permanent damage within 24 to 48 hours. If you experience these symptoms, remove your lenses and call us immediately. Bring your lenses and case to your appointment so we can test them for the specific organism causing your infection.
Frequently Asked Questions
No, never rinse or store your contact lenses in tap water. Even clean-looking tap water contains microorganisms like Acanthamoeba that can cause devastating eye infections. These parasites resist normal disinfection and can lead to months of painful treatment or permanent vision loss. Always use fresh multipurpose solution or sterile saline specifically labeled for contact lenses.
We strongly advise against sleeping in contact lenses unless they are specifically FDA-approved for overnight wear. Even one night increases your risk of corneal swelling, infection, and oxygen deprivation. If you accidentally fall asleep in your lenses, remove them as soon as you wake up, let your eyes recover without lenses for several hours, and watch for any signs of irritation or redness.
Follow the labeling for your specific solution. If lenses remain stored longer than the time indicated on the bottle, repeat the full clean and disinfect cycle before wearing. Many products require re-disinfection if stored more than 24 hours to 7 days. When in doubt, discard the stored lenses and start with a fresh pair.
Never reuse solution or top off partially used solution in your case. Each time you store your lenses, empty the old solution completely and fill the case with fresh solution from the bottle. Used solution loses its disinfecting power and becomes contaminated with bacteria, proteins, and debris from your lenses. This practice is one of the leading causes of preventable contact lens infections.
Do not try to remove your lenses immediately upon waking. First, add rewetting drops or preservative-free artificial tears to rehydrate your eyes. Wait a few minutes, blink gently, and then try to remove the lenses once they have loosened. Give your eyes a rest without lenses for the rest of the day. Contact our office if you experience pain, redness, or vision changes that persist after removal.
No. Scleral and orthokeratology lenses have unique wear schedules and care systems. Follow the instructions provided by your fitter for those lenses.
