This newsletter explains how to protect your eyes before swimming in chlorinated pools during summer. It shares an ophthalmologist’s five key tips: wear snug UV-protective goggles, avoid contact lenses, rinse and lubricate eyes afterward, guard against UV exposure, and seek medical help for persistent redness or vision changes.
Summer Splash is an eye care guide that aims to help people have fun and avoid these five common pitfalls.
With the summer heat on the rise and pools filling up, keeping your eyes safe is as critical as keeping your skin safe. Chlorinated water, microbes and UV rays can irritate, or even do damage, to your eyes if you dive unprepared. Your ophthalmologist can help you have a safe, fun and eye-healthy summer while swimming with some simple tips.
The reasons why pool water can cause damage to your eyes.
Though a swimming pool might appear clean, chemical and germs in the pool can cause the eye to lose its natural tear film layer and damage the cornea. After long-term exposure, a redness, dryness, itching and a gritty sensation often occur. The risk of infection and even serious complications to the cornea is even greater for contact lens wearers.
Tip One: Always wear well-fitted goggles.
Swimming goggles provide a barrier to pool water and protect your eyes. Anti-fog, UV-protective, well-sealed goggles help to avoid chlorine, microbe, and bright light irritation. Frequent swimmers and children in particular can benefit from having goggles as much a part of their swimming gear.
Tip Two: Do not wear contact lenses in the pool!
Wearing contact lenses while swimming will allow contaminated water to be trapped against the eye's surface. This puts one at risk of infections like keratitis that may endanger one's vision. If you do need to use them, daily disposables with tight fitting goggles are preferable and then the lenses should be discarded straight after swimming.
Tip Three: To help avoid this, rinse or wipe the rod first, and then lubricate.
Once out of the pool, rinse off closed eyelids with clean fresh water, pat dry. Dryness, discomfort or burning may benefit from preservative free lubricating eye drops to restore moisture. Do not rub your eyes with your hands too hard, as it can aggravate the irritation or micro-scratches.
Tip Four: Protect from the UV rays
Exposure to the sun's intense ultraviolet rays at outdoor pools can lead to cataracts and other surface damage to the eye. Widely brimmed hat and sunglasses with 100% UV protection provide extra protection between laps. UV protection is important even on cloudy days for long-term eye health.
TIP #5: Be Watchful of Warning Signs
If the eye keeps red, painful, and/or has decreased vision, sensitivity to light, or fluid that drains from it after swimming, the child may have an eye infection or injury to the cornea. If you seek immediate treatment from an ophthalmologist, you will be able to prevent complications and save your vision. It is important for parents to carefully watch children, as they may not be able to communicate their discomfort.
