I love travelling and the tropics are one of my favourite destinations. Great food, bath tub warm seas and beautiful beaches. However travellers wearing contact lenses should be extra careful in tropical climes. The warmth and humidity are great environments for fungi, amoebi and bacteria to flourish, and a contact lens related infective ulcer can bring a rapid end to your holiday and worse still, permanent loss of vision in some cases.
Advice for safe contact lens wear whilst travelling through tropical climes are to never swim with contact lenses (you can with goggles to prevent water getting into the eye), always wash your hands and dry them before handling your lenses, never wash your lenses in tap water, never sleep in your lenses, always clean them and store them in a clean container, better still- consider daily disposable lenses. If your eyes do become red or painful immediately stop wearing your lenses If the discomfort persists for longer than a day you should try and see an eye doctor as soon as possible. If you can't find a doctor find an optician.
In South East Asia excellent ophthalmic care can be found in Singapore and Thailand or the capital cities of most countries. If you are in the middle of no where and can't find a doctor you may be able to obtain antibiotics such as levofloxacin, ofloxacin or cefuroxime every hour, which may be used in an emergency. Never use steroid containing eye drops without a eye doctors advice. Steroid drops promote fungal growth and can make things a lot worse. Some drops contain antibiotics and steroids together and you should be aware of this. You should seek the advice of an expert as soon as possible.
If you're considering laser eye surgery before your round the world trip you should plan ahead and consider having it done at least a month before for full recovery.
Have a great holiday and stay safe!
