Eye Care for Swimmers
Common Eye Problems Swimmers Face
Red, bloodshot eyes are one of the most common complaints we hear from swimmers. The redness happens when blood vessels on the surface of your eye swell in response to irritants in the water. Your eyes may also feel gritty, burn, or itch for hours after you finish swimming.
Most cases of post-swim redness clear up on their own within a few hours. However, if your eyes stay red for more than a day or if the irritation gets worse, we recommend scheduling an examination to rule out infection or other complications.
Chemical conjunctivitis, often called swimmer's eye, occurs when pool chemicals irritate the clear membrane covering the white part of your eye. This condition causes redness, watering, and a mild burning sensation that typically develops within minutes of exposure. Unlike bacterial or viral conjunctivitis, chemical conjunctivitis is not contagious.
The symptoms usually fade within a few hours once you irrigate your eyes with sterile saline or use preservative-free artificial tears and give them time to recover. Avoid tap water in your eyes. We may recommend artificial tears to help flush out residual chemicals and soothe the irritation.
Chlorine keeps pools clean, but it can disrupt the natural tear film that protects your eyes. When chlorine breaks down this protective layer, your eyes become vulnerable to additional irritants. Common symptoms include:
- Stinging or burning sensation during and after swimming
- Blurry vision that clears after blinking or rinsing
- Excessive tearing as your eyes try to flush out the chemical
- Sensitivity to light when you leave the pool area
Pools, lakes, rivers, and oceans can harbor bacteria, viruses, and parasites that cause eye infections. Acanthamoeba is a parasite found in both tap water and natural bodies of water that can lead to serious corneal infections. Bacterial infections like those caused by Pseudomonas can develop if contaminated water gets into your eyes.
Adenoviruses can spread easily in inadequately chlorinated pools and cause highly contagious conjunctivitis. Anyone with red, draining eyes should avoid swimming to prevent spreading infection.
These infections typically cause more severe symptoms than simple irritation, including thick discharge, significant pain, blurred vision, and swelling of the eyelids. We take any suspected infection seriously because early treatment prevents complications that could threaten your vision.
Most swimming-related eye issues are temporary and mild, but certain warning signs require immediate attention. Contact our eye doctor right away if you experience:
- Severe eye pain that does not improve with rinsing
- Vision changes that persist after you dry off and blink
- Discharge that is thick, yellow, or green in color
- Sensitivity to light that worsens over several hours
- A feeling that something is stuck in your eye that will not go away
- If you wear contact lenses and have eye pain, light sensitivity, or reduced vision, seek same-day care due to the risk of a corneal infection
Why Swimming Puts Your Eyes at Risk
Pool operators add chlorine to kill harmful microorganisms, but when chlorine mixes with sweat, urine, and personal care products in the water, it forms chloramines. These compounds are actually what cause that strong chlorine smell and most of the eye irritation swimmers experience. A well-maintained pool with properly balanced chemicals causes less irritation than a pool with high chloramine levels.
The pH level of pool water also matters for eye comfort. Your tears have a pH of about 7.4, while pool water typically ranges from 7.2 to 7.8. Even small differences in pH can disrupt your tear film and cause stinging or burning sensations.
No swimming environment is completely sterile. Pools can become contaminated when swimmers do not shower before entering or when someone with an infection uses the water. Natural bodies of water contain environmental microorganisms that normally do not cause problems unless they contact vulnerable eye tissues.
Warm, stagnant water poses the highest risk for bacterial growth. We see more swimming-related infections during hot summer months when people swim in ponds, slow-moving creeks, and warm lake areas where bacteria thrive. Hot tubs pose especially high risk for bacterial and amoebic organisms; avoid hot tubs, and never wear contact lenses in them.
Contact lenses create a serious risk when combined with swimming. The lenses can trap bacteria, parasites, and contaminated water against your cornea, dramatically increasing your infection risk. Acanthamoeba keratitis, a painful and difficult-to-treat infection, occurs much more frequently in contact lens wearers who swim or shower while wearing their lenses. This applies to all lens types, including soft, rigid gas permeable, and scleral lenses.
Even brief water exposure can allow your contact lenses to absorb microorganisms. The lenses may also change shape, move around, or fall out when exposed to water, and swimming can wash away the disinfecting solution meant to keep your lenses clean.
Some people face higher risks when swimming. Children often experience more eye irritation because they spend more time underwater and are less likely to wear goggles consistently. People with dry eye disease or other existing eye conditions may find that swimming worsens their symptoms.
Contact lens wearers, competitive swimmers who train for many hours each week, and people who swim in inadequately chlorinated or natural water face elevated infection risks. We pay special attention to these groups and recommend extra precautions.
Protecting Your Eyes While Swimming
Properly fitted swim goggles create a watertight seal that keeps pool chemicals and contaminated water away from your eyes. Look for goggles with soft, flexible gaskets that conform to the shape of your face without causing pressure points. The lenses should provide clear vision and, if you swim outdoors, offer UV protection to shield your eyes from sun damage.
We recommend trying on several styles to find goggles that fit your face shape comfortably. Hold the goggles against your face without putting the strap over your head. If they create gentle suction and stay in place for a moment, the fit is likely good. For outdoor swimming, choose lenses with UV400 protection; polarized lenses can help with glare.
Even the best goggles will not protect your eyes if they do not fit correctly. Adjust the straps so the goggles feel snug but not painfully tight. The seal should rest on the soft tissue around your eye sockets, not on your eyeballs themselves.
Replace your goggles when the gaskets become stiff or cracked, when the straps lose elasticity, or when you can no longer achieve a good seal. Rinse your goggles with fresh water after each use and store them in a protective case to prevent damage. Do not share goggles. Avoid touching or rubbing the inner surface of the lenses; allow them to air dry after rinsing with fresh water.
We strongly recommend removing your contact lenses before swimming, even if you plan to wear goggles. The safest approach is to swim without contact lenses or to use prescription swim goggles.
If you absolutely must wear contact lenses while swimming, wear tight-fitting goggles and remove your lenses immediately afterward. For daily disposables, discard them. For reusable lenses, place them in a new case with fresh disinfecting solution and complete a full disinfection cycle; do not reinsert the same day. Consider replacing reusable lenses after any water exposure.
Never rinse your contact lenses with tap water or store them in anything other than fresh sterile solution. Saline is not a disinfectant. Daily disposable lenses may be considered in specific cases for swimmers who cannot function without vision correction, but they must be discarded immediately after water exposure and should not be considered fully protective. Never wear contact lenses in hot tubs or while showering.
Preparing your eyes before you swim can reduce irritation. Consider using lubricating eye drops before entering the water to add an extra layer of moisture to your eyes. Check that your goggles are clean and properly adjusted before you dive in. If you use lubricating drops more than four times a day, choose preservative-free formulations.
After swimming, rinse your face with fresh water. For your eyes, irrigate with sterile saline or use preservative-free artificial tears; avoid putting tap water directly in your eyes. Avoid rubbing your eyes, which can introduce bacteria from your hands. If your eyes feel dry or irritated, we may recommend preservative-free artificial tears to help restore comfort.
Children may resist wearing goggles, but making them a fun, non-negotiable part of swimming helps establish good habits. Let your child pick out goggles in their favorite color or featuring characters they like. Check the fit regularly as children grow quickly and may need new goggles each season.
Competitive swimmers who train daily face cumulative exposure to pool chemicals. We recommend these athletes invest in high-quality goggles, use lubricating drops regularly, and schedule periodic eye exams to catch any early signs of chronic irritation or other problems. Swimmers training for several hours each day should take short breaks to give their eyes a rest from chemical exposure. People who have had recent eye surgery should avoid swimming until their surgeon confirms it is safe.
Treating Swimming-Related Eye Problems
If your eyes feel uncomfortable after swimming, start by irrigating them with sterile saline. Flush your eyes for several minutes. If a chemical splash or unknown substance is involved, irrigate for 15 minutes and seek urgent care. Avoid rubbing your eyes, even though they may itch, because rubbing can cause additional damage to already irritated tissues. Wash your hands before touching your eyelids or lashes.
Remove any eye makeup and give your eyes a break from contact lenses for at least 24 hours. Rest in a dimly lit room if you are experiencing light sensitivity. Most mild irritation resolves within a few hours with these simple measures. A cool compress for 10 minutes can also reduce discomfort.
We often recommend preservative-free artificial tears for swimmers dealing with dry, irritated eyes. These lubricating drops help rinse away residual irritants and restore the protective tear film on your eye surface. You can use them as often as needed without worry about preservative-related irritation.
Avoid using redness-relieving drops that contain vasoconstrictors for swimming-related irritation. These products may make your eyes look better temporarily, but they do not address the underlying problem and can cause rebound redness with regular use. If artificial tears do not provide relief within a day, contact our office for an evaluation. If symptoms have an allergic component, antihistamine and mast cell stabilizer drops may help; ask your eye care provider.
When you visit our office with swimming-related eye complaints, we will ask detailed questions about your symptoms, when they started, and where you were swimming. Our eye doctor will examine the surface of your eyes using a special microscope called a slit lamp to check for signs of infection, inflammation, or damage to your cornea.
If we suspect an infection, we may collect a small sample from your eye to identify the specific organism causing the problem. This helps us determine the most effective treatment. We may also check your eye pressure and examine your internal eye structures to make sure no deeper problems exist.
Bacterial eye infections require antibiotic drops or ointments that we prescribe based on the specific bacteria involved. Treatment typically lasts five to seven days, and improvement usually begins within 48 hours. If we diagnose a parasitic infection like Acanthamoeba keratitis, treatment is more complex and may involve specialized antimicrobial drops used for several weeks or months.
For severe inflammation without infection, we may recommend anti-inflammatory medications to reduce swelling and discomfort. Topical steroid drops should only be used after infection has been ruled out and under close supervision. Follow the prescribed schedule carefully and finish the entire course of medication even if your symptoms improve quickly. Stopping treatment too soon can allow infections to return or develop resistance.
Simple chemical irritation from pool water typically resolves completely within 24 hours. Mild bacterial infections usually improve within a few days of starting antibiotic treatment, with full recovery in one to two weeks. More serious infections, especially parasitic ones, may require weeks or months of treatment and close monitoring. Corneal abrasions from water impact or goggle pressure usually heal within 24 to 72 hours; avoid contact lens wear until healed and symptom free.
We will schedule follow-up appointments to ensure your condition is healing properly. Contact our office sooner if your symptoms worsen during treatment or if you develop new problems like increased pain or vision changes. Most swimmers make a full recovery and can return to the pool once their eyes have healed completely.
Returning to the Pool Safely
If you experienced only mild irritation without infection, you can usually return to swimming once your symptoms have completely resolved and your eyes feel normal again. This typically takes one to two days. Make sure you have properly fitting goggles before you go back in the water to prevent the same problem from happening again.
Listen to your body and avoid pushing yourself to swim if your eyes still feel sensitive or uncomfortable. Returning to the pool too soon can prolong your recovery and may lead to more serious irritation or secondary infection. If you had a corneal abrasion or wore contact lenses when symptoms began, get clinician clearance before returning to the pool.
Eye infections require more caution before resuming swimming. We generally recommend staying out of the water until you have completed your full course of prescribed medication and our eye doctor confirms that the infection has cleared completely. For uncomplicated bacterial conjunctivitis, this may be about one to two weeks after starting treatment. Corneal infections such as ulcers or Acanthamoeba keratitis often require a much longer restriction. Follow your clinician's clearance.
Swimming with an active infection risks spreading it to other people and can slow your own healing. Pool chemicals may also interfere with your medication or irritate your healing eye tissues. When we give you clearance to swim again, start gradually and pay attention to any returning symptoms.
Preventing future eye problems starts with consistent goggle use. Make wearing goggles as automatic as putting on a swimsuit. Keep a spare pair in your swim bag in case your primary goggles break or develop leaks.
- Showering before swimming to reduce the organic matter that creates chloramines
- Choosing well-maintained pools with proper chemical balance
- Avoiding swimming when you have any eye irritation or infection
- Scheduling regular eye exams if you swim frequently
- Never swim or shower while wearing contact lenses; avoid hot tubs altogether or strictly without lenses
- Do not share goggles, and replace goggles that no longer seal well
- Avoid spitting in goggles; use products labeled for anti-fog and rinse as directed
- Replace contact lens cases every three months and never top off solution
Certain symptoms indicate your eyes have not fully healed and need more recovery time. Do not swim if you experience:
- Ongoing redness
- Discharge of any kind
- Pain or discomfort
- Blurred vision
- Sensitivity to light
- New floaters, flashes of light, or a curtain over part of your vision after diving or impact
These signs suggest active inflammation or infection that could worsen with water exposure. If you have started swimming again but notice any returning symptoms, stop immediately and contact our office. Some infections can seem to improve but then flare up again when exposed to pool water or other irritants too soon after treatment.
Frequently Asked Questions
While you physically can open your eyes underwater, we do not recommend it. Exposing your unprotected eyes to pool chemicals or natural water contaminants causes unnecessary irritation and increases infection risk. If you need to see underwater, wearing goggles is much safer than opening your eyes directly to the water.
Saltwater pools actually still use chlorine for sanitation, but they generate it from salt rather than adding it directly. These pools may cause slightly less irritation for some people because they typically maintain more consistent chlorine levels. However, they can still irritate your eyes and do not eliminate the need for goggles.
Prescription swim goggles help you see clearly while protecting your eyes from water exposure. They are an excellent investment if you swim regularly and cannot function safely without vision correction. Many sporting goods stores and online retailers offer swim goggles in a range of prescription strengths.
Anti-fog spray or gel products applied to the inside of your goggle lenses can help maintain clear vision. Some swimmers rinse their goggles with a small amount of baby shampoo and let them dry, which creates an anti-fog coating. Avoid touching the inside of the lenses with your fingers, as skin oils promote fogging. If you use any anti-fog product, ensure it is labeled for goggles and rinse thoroughly; avoid saliva or products that can leave residue that irritates the eyes.
Swimming in natural water with an existing eye condition depends on the specific problem you have. Minor issues like mild dry eye may not worsen with well-protected swimming, but active infections, corneal abrasions, or recent eye surgery require complete water avoidance. Always ask our eye doctor before swimming if you have any eye health concerns. If you have had recent eye surgery, avoid swimming until your surgeon confirms it is safe.
