Rewetting Drops for Contact Lenses
Signs You May Need Rewetting Drops
Many contact lens wearers notice their lenses feel fine in the morning but become uncomfortable as the day goes on. This gradual increase in discomfort often means your lenses are losing moisture and need extra hydration.
If you find yourself wanting to remove your contacts before the end of your workday or evening activities, rewetting drops may provide the relief you need.
When your contacts start to dry out, you might experience moments of blurred or hazy vision. Blinking a few times may temporarily clear your sight as your natural tears redistribute across the lens surface.
This pattern suggests your tear film is not maintaining adequate moisture on your lenses. Rewetting drops can help stabilize your vision and reduce the need for frequent blinking.
A scratchy, sandy, or gritty sensation while wearing contacts is a classic sign of lens dryness. Your eyes may feel as though something is stuck under the lens, even when nothing is there.
- The feeling often worsens in air-conditioned or heated environments
- Wind and dry climates can make the sensation more intense
- Grittiness tends to increase during activities that reduce blinking
- The discomfort may affect one or both eyes
Dry contact lenses can cause your eyes to appear red or bloodshot. The irritation occurs because dry lenses create friction against the surface of your eye with each blink.
While mild redness may respond well to rewetting drops, persistent or severe redness requires an eye doctor evaluation to rule out infection or other complications. If your eyes become very red or painful, remove your contact lenses immediately and do not reinsert them until you are examined and cleared by an eye care professional.
If you used to wear your contacts comfortably for 12 to 14 hours but now struggle to make it through eight hours, dryness is likely the culprit. Your wearing time may gradually decrease as your lenses lose their ability to stay properly hydrated.
Rewetting drops can often extend your comfortable wearing time, though you may also need to explore other solutions if drops alone do not solve the problem.
Why Contact Lenses Become Dry
The environment around you plays a major role in how well your contact lenses stay moist. Low humidity, air conditioning, heating systems, and wind all pull moisture away from your lenses faster than your tears can replace it.
- Airplane cabins have extremely low humidity that rapidly dries lenses
- Office buildings often have dry air from HVAC systems
- Outdoor activities in windy or arid climates accelerate evaporation
- Fans blowing directly toward your face increase lens drying
When you focus on a computer, phone, or tablet, your blink rate can drop by more than half. Blinking spreads your natural tears across your contact lenses, so fewer blinks mean less moisture distribution.
Digital device use is a common contributor to contact lens dryness. Taking regular breaks and using rewetting drops can help counteract this effect.
Different contact lens materials have different water content levels and surface treatments that affect how they interact with your tears. Some higher water content hydrogels can feel drier by the end of the day because they draw moisture from the tear film, while silicone hydrogel lenses provide high oxygen transmission and often rely on surface treatments or internal wetting agents to maintain comfort. Your eye care professional can help match a lens material and surface technology to your tear film and eyelids.
Some people have an underlying condition that reduces the quality or quantity of their natural tears. Dry eye disease can make wearing contact lenses challenging because your eyes do not produce enough tears to keep lenses comfortable.
If you have chronic dry eye, you may need treatment for the underlying condition in addition to using rewetting drops. Many patients with dry eye disease can still wear contacts successfully with the right treatment plan.
Certain medications can decrease your natural tear production as a side effect. Antihistamines, decongestants, blood pressure medications, antidepressants, and hormone therapies are among the most common culprits.
- Birth control pills may reduce tear quality in some wearers
- Acne medications can affect oil glands in the eyelids
- Diuretics decrease overall body fluid, including tears
- Sleep aids and anti-anxiety medications may reduce tear production
Your tears contain proteins and oils that naturally deposit on contact lenses over time. These deposits create an uneven surface that disrupts the tear film and causes dry spots on the lens.
Even with proper cleaning, deposits can accumulate and make your lenses feel dry. Rewetting drops can provide temporary comfort, but heavily deposited lenses need to be replaced to restore full comfort. If deposits recur early, your care system may need to be changed, or your lenses may need to be replaced more frequently.
Types of Rewetting Drops for Contact Lenses
Preservative-free rewetting drops come in single-use vials and contain no chemicals to prevent bacterial growth. These drops are gentler on your eyes and are the preferred choice for people with sensitive eyes or those who need to apply drops frequently throughout the day.
Preserved drops come in multi-use bottles and contain small amounts of preservatives to keep the solution sterile after opening. While more convenient and economical, some people may experience irritation from the preservatives, especially with frequent use. Avoid drops containing benzalkonium chloride while wearing soft lenses, as this preservative can bind to lenses and irritate the eye.
Soft contact lenses are made from porous materials that can absorb substances from the drops you use. Rewetting drops designed for soft lenses are specifically formulated to be compatible with these materials and will not damage or discolor your lenses.
- These drops often contain ingredients that bind to the lens surface
- They help restore the moisture cushion between your eye and the lens
- Many brands offer different formulas for specific soft lens types
- Using the correct drops helps maintain comfort and wettability between scheduled replacements
Rewetting drops should not be used to extend wear beyond the prescribed replacement schedule.
Rigid gas permeable lenses require different rewetting solutions than soft lenses. RGP rewetting drops are formulated to work with the hard, non-porous surface of these lenses and contain ingredients that help the lens glide smoothly across your eye.
Use only drops labeled as compatible with your lens type. Do not mix formulations unless the product specifically states it is safe for both soft and RGP lenses. With RGP wear, dryness symptoms can relate to lens fit or edge design; adjustments can improve comfort.
Lubricating rewetting drops contain special moisturizing ingredients that coat your lenses and provide longer-lasting comfort. These drops are designed to supplement your natural tears and keep lenses hydrated for extended periods.
Saline solutions, on the other hand, are primarily designed for rinsing and storing lenses, not for rewetting while wearing them. While saline may provide brief relief, it lacks the lubricating ingredients needed for lasting comfort and evaporates quickly from the lens surface. For scleral lenses, preservative-free sterile saline is used to fill the lens bowl at insertion and may also be used during the day as directed by your eye care professional.
Many artificial tear products sold for dry eyes are not approved for use with contact lenses in place. These drops may contain ingredients that can damage lens materials, cause deposits to form, or get absorbed into soft lenses and irritate your eyes.
- Some ingredients in regular eye drops can cloud or discolor lenses
- Certain preservatives may accumulate in soft lens materials
- Oils and ointments will coat lenses and blur vision
- Always check that drops are specifically labeled as contact lens compatible
- Avoid vasoconstrictor redness-relief drops with contacts, as they can worsen irritation and are not formulated for lens wear
- Avoid drops with benzalkonium chloride while lenses are in, due to lens binding and toxicity risk
How to Choose and Use Rewetting Drops
When you mention contact lens dryness, your eye care professional will examine your tear quality, lens fit, and the condition of your eye surface. They look for signs of inflammation, deposits on your lenses, and how well your tears spread across the lens surface.
This evaluation helps determine whether rewetting drops alone will solve your discomfort or if you need other interventions. Your lens type, wearing schedule, and symptoms that might indicate a more serious problem are all considered.
Before recommending specific rewetting drops, your eye care professional will confirm exactly which type of contact lenses you wear. The product packaging or prescription records tell you whether you use soft lenses, RGP lenses, or specialty lenses that may require particular formulations.
- Daily disposable lenses often work well with preservative-free drops
- Extended wear lenses may need drops with specific preservative systems
- Toric and multifocal lenses have the same rewetting drop needs as regular soft lenses
- Scleral lenses are filled with preservative-free sterile saline at insertion; ask which on-eye rewetting drops or saline are appropriate for midday comfort
- Orthokeratology lenses worn overnight require specific solutions and instructions; do not substitute rewetting drops for your prescribed care system
Wash and dry your hands before handling the bottle. To apply rewetting drops, tilt your head back slightly and look up. Gently pull down your lower eyelid to create a small pocket, then squeeze one or two drops onto your eye while keeping the bottle tip from touching your eye, eyelid, or lashes.
After applying the drops, blink several times to help spread the solution across your lens. Wait a minute before resuming activities to allow the drops to fully distribute and provide maximum comfort. Drops can temporarily blur vision; avoid instilling while driving. If stinging or burning persists after application, remove your lenses and seek advice.
Most rewetting drops can be used as often as needed throughout the day. Preservative-free formulations are safe for very frequent use, even every hour if necessary for comfort. If you need drops more than a few times daily, choose preservative-free formulations to minimize preservative exposure.
If you find yourself needing drops more than four to six times daily, let your eye care professional know. Excessive dryness may signal that you need a different contact lens type, treatment for underlying dry eye, or a change in your wearing schedule. If you are using prescription medicated eye drops, remove contact lenses and wait at least 10 to 15 minutes after instillation before reinserting, unless directed otherwise.
Simple daily habits can help reduce dryness and improve your contact lens comfort. These strategies work well alongside rewetting drops to keep your lenses hydrated throughout the day.
- Follow the 20-20-20 rule and practice full blinks to improve tear spread
- Use a humidifier in dry environments
- Aim fans and air vents away from your face
- Wear wraparound glasses or moisture chamber glasses in wind
- Stay hydrated and manage allergies and eyelid hygiene as advised
- Consider switching to a hydrogen peroxide care system for soft lenses if deposits are an issue, after consulting your provider
Store your rewetting drops at room temperature and away from direct sunlight. Keep the bottle cap tightly closed when not in use to prevent contamination and maintain sterility.
- Check the expiration date before using any drops
- Discard multi-use bottles according to package directions, typically 30 to 90 days after opening
- Never share your rewetting drops with others
- Throw away any drops that change color or appear cloudy
- Wash your hands before handling the bottle
- If the bottle tip touches your eye, lashes, or skin, consider the bottle contaminated and replace it
When Rewetting Drops Are Not Enough
If rewetting drops provide only temporary relief, your eye care professional may recommend switching to a lens material with better moisture retention. Newer silicone hydrogel materials and daily disposable lenses often stay more comfortable throughout the day than older lens types. Higher oxygen transmission can improve comfort and corneal health, but moisture retention depends on surface treatments and wetting agents.
Some patients benefit from lenses specifically designed for dry eyes, which have special surface treatments or materials that resist drying. Your eye care professional can discuss the latest lens options that match your prescription and lifestyle needs. Rewetting drops do not make overnight wear safer; sleeping in lenses increases the risk of infection.
Cutting back on how long you wear your contacts each day can give your eyes more time to recover and produce natural tears. Your eye care professional might suggest wearing your contacts only during work hours or social activities and switching to glasses in the evening.
Many contact lens wearers find that reducing their wearing time by even two to three hours daily makes a significant difference in comfort. This approach allows you to continue enjoying contacts while protecting your long-term eye health. Do not use rewetting drops to push through significant discomfort; remove lenses and switch to glasses if symptoms persist.
When chronic dry eye disease makes contact lens wear difficult, treatment targets the underlying cause. Options include prescription anti-inflammatory eye drops, tear-stimulating therapies, consistent eyelid hygiene and warm compresses to improve meibomian gland function, and in-office procedures that target gland obstruction. Dietary omega-3s may help some patients, but benefits vary and should be discussed with your clinician.
- Prescription drops targeting inflammation can improve tear production
- Lid hygiene helps maintain healthy oil glands needed for quality tears
- Punctal plugs may be considered in specific cases to retain tears longer
- Treating allergies can reduce inflammation that worsens dryness
For contact lens wearers with severe dryness that does not respond to rewetting drops or over-the-counter treatments, prescription medications that increase tear production or reduce inflammation may be recommended. These prescription therapies can take several weeks to show full benefit but often make a substantial difference. Most prescription drops should not be used while lenses are in place; remove lenses and wait at least 10 to 15 minutes before reinserting, or follow your prescriber's instructions.
Your eye care professional can discuss whether prescription treatment is appropriate for your situation. Short courses of topical steroids may be used under close supervision. Never self-prescribe steroids, and do not wear contact lenses while using them unless specifically instructed.
Some symptoms indicate a serious problem that needs immediate attention rather than just rewetting drops. Remove your contact lenses immediately if these symptoms occur and do not reinsert them. Contact the office right away if you develop sudden severe pain, significant vision loss, intense light sensitivity, discharge from your eye, or if your eye remains very red after removing your contacts.
- Pain that continues after lens removal may signal a corneal injury
- White spots on your eye or colored halos around lights need urgent evaluation
- Thick discharge or crusting suggests possible infection
- Extreme redness in one eye more than the other requires prompt examination
- Any trauma to your eye while wearing contacts needs immediate assessment
- Bring your lenses, case, and solutions to your visit for evaluation
Frequently Asked Questions
Most regular eye drops are not safe to use while wearing contact lenses because they contain ingredients that can damage lens materials or get absorbed into soft lenses. Only use drops that are specifically labeled as safe for use with contacts, and remove your lenses before using any medicated eye drops unless your eye doctor instructs otherwise. Avoid redness-relief vasoconstrictor drops with contacts.
Multi-use bottles of rewetting drops typically remain safe for 30 to 90 days after opening, depending on the specific product and preservative system. Check the package insert for exact guidelines, and write the opening date on the bottle so you know when to discard it. Preservative-free single-use vials should be discarded immediately after one use and never saved for later.
Rewetting drops cannot repair physical damage to contact lenses. If your lens has a tear, scratch, or chip, you must replace it even if drops temporarily improve comfort. Wearing damaged lenses can scratch your cornea and lead to serious infections, so always inspect your lenses carefully and discard any that show signs of damage.
Never make homemade rewetting solutions or use water, saliva, or any non-sterile liquid with your contact lenses. Homemade solutions lack proper sterility and pH balance, which can lead to severe eye infections including those caused by dangerous microorganisms. Only use commercially prepared products specifically designed and approved for contact lens rewetting.
Wait at least 10 to 15 minutes after instilling medicated drops before reinserting your lenses, and follow the drug label or your doctor's instructions. Many prescription drops should not be used with lenses in place.
No. Rewetting drops do not reduce the risks associated with sleeping in contact lenses. Overnight wear increases the risk of infection.
Mild, brief blur is common. If stinging, burning, or blurred vision persists, remove your lenses, stop using the drops, and contact your eye care professional.
Getting Help for Rewetting Drops for Contact Lenses
