Contact lenses provide huge conveniences over wearing prescription spectacles while travelling, but they can come with potential hazards. Our guide to hygienic contact lens usage will help you plan your trip with 20/20 vision.
Handling your contact lenses
Most of us have been guilty of reusing contact lens solution on lazy nights, or taking off our lenses with grimy fingers.
Avoid these habits in the future, as failing to clean your lenses properly or handling them with dirty hands can cause bacteria to breed, hence causing infection.
Suggested duration of use
Users who wear their lenses for long hours, or past their expiry date have to be wary of possible eye infections. Always replace your lenses as prescribed by your ophthalmologist. It's recommended that daily disposable contact lenses be used for a maximum of 12 hours, and never worn overnight.
Washing your contacts
Wash your contact lenses with the appropriate sterile solution once a day. Gently rub your lenses to clean them better while rinsing them with the solution.
Don't be stingy: use fresh solution in your case every time. Do not top up from the remaining solution, to prevent bacteria build-up.
To prevent contamination, wash your contact lens case and rinse it with fresh solution as well. Discard and replace a fresh case once every 3 months.
Avoid using water as a substitute cleanser
In this case, water is (literally) not a solution, and may contain microbes and viruses that can cause eye infections. Always opt for the appropriate sterile solution instead.
Consider daily contact lenses
For those who want maximum convenience, choose daily disposable contact lenses. This lets you skip the rigour of cleaning and storage.
Get annual eye check-ups
Regular eye checks are useful to detect cornea wear and tear, especially if you're a contact lens user.
Contact lens users often run the risk of having damaged or weakened corneas due to prolonged years of wearing them. When in doubt, consult an ophthalmologist for advice.
Hitting the road for a trip? Bear these essential tips in mind for hygiene and care.
Keep those hand wipes handy
Have disinfected hand wipes, a hand sanitiser on hand, or go to a sink so that you can wear and remove your lenses in the most hygienic way no matter where you are when traveling.
Consider the country and climates
Replace your contact lenses often if you're in cities or other areas with lots of dust, dirt and smoke. You can also consider using daily disposable contact lenses for convenience and to reduce the risk of infection, since there will be no concerns regarding cleaning and storage of the lenses. If you're in an arid environment, pack lubricating eyedrops to wet your eyes as they may get very dry under those conditions.
Pack your prescription
If you're on a far-flung trip to an exotic locale, bring your prescription along in case of language barriers. You'll be able to approach an eye clinic if you require an emergency pair of contact lenses. But it's still best to bring extra pairs of contact lenses.
Wear those eyeglasses
Even if you wouldn't dream of ruining your selfies with eyeglasses, pack them for unexpected circumstances and as stand-ins.
Your eyes will need to take a break from your lenses after a long day out, or if you're looking to nap on that long train ride.
Avoid contact lenses for water activities
Hands up if you've swam with your contact lenses in the depths of the ocean or the hotel's swimming pool. While the convenience is certainly appealing, you run the risk of fungal and bacterial eye infections. If you do need to wear contact lens for water activities, the option would be to use a pair of daily contact lenses and discard them after. You could alsp wear your regular lenses (if they're weekly, or monthly disposables), and change to a new pair after the activity.
If you've dropped your lenses in an alley or sidewalk, don't try to re-use them – bacteria can still be present on both sides of your lenses. Instead, carry a spare pair, or two, when you travel.
Despite our best efforts to keep our fingers clean and eyes safe, here are some common eye conditions that may just creep up on us.
Conjunctivitis and other eye infections
At the most basic level, dirty contact lenses can cause eye irritation and discomfort, but these issues can quickly evolve into common eye infections such as conjunctivitis (also known as 'Pink Eye').
When irritants such as smoke, dust, and even make-up build up on the lenses, one's eyes can become red, itchy or experience a burning and stinging sensation. In serious cases, prescribed antibiotic eyedrops from a doctor may be required.
In dry climates, your eyes may experience more redness and irritation than usual if you're wearing contact lenses.
Another common infection is the eye stye – a localised infection in or on the eyelid that looks like a boil or pimple. You may feel both pain and an increased sensitivity to light. If you do have an eye stye, stop contact lens wear immediately.
Wearing dirty contact lenses for prolonged periods may cause corneal ulcers and abrasions, making the eye sensitive to light. If you're experiencing any of the following symptoms, consult a healthcare professional immediately:
Should you have a question regarding the health of your eyes, or if you are experiencing persistent discomfort, contact an ophthalmologist for an eye check up.
