A Bali Pool Visit Led to a Parasite Eating at His Cornea
Most travelers pack sunscreen and insect repellent before a trip to Bali. Contact lens wearers may want to add one more item to their pre-departure checklist: awareness of acanthamoeba keratitis, a rare but serious parasitic eye infection that one British traveler learned about the hard way.
Matt Flack, a 38-year-old from the United Kingdom, spent two months in Bali beginning in May, swimming in pools while wearing his contact lenses. He initially dismissed the discomfort in his left eye as irritation from sand and saltwater picked up while surfing. When he removed his lenses, the problem did not resolve. He eventually found himself unable to open that eye.
Subsequent scans and corneal microscopy confirmed he had acanthamoeba keratitis (AK), a condition caused by a microscopic amoeba that can invade the cornea. As Flack described it to reporters, per PEOPLE and Kennedy News and Media, "It's essentially a parasite eating away at my eye." He admitted to feeling genuine fear about losing the eye entirely. His doctors have placed him on a three-month course of medicated drops in an attempt to eliminate the infection, though his prognosis remains uncertain.
What Is Acanthamoeba Keratitis?
Acanthamoeba is a microscopic organism found in many water environments, including swimming pools, hot tubs, tap water, and natural bodies of water. For most people, exposure is harmless. Contact lens wearers face a specific vulnerability: lenses can trap the organism against the corneal surface, allowing it to penetrate the eye's tissue. Symptoms include significant eye pain, a persistent sensation of a foreign object in the eye, excessive watering, sensitivity to light, redness, and blurred or clouded vision.
Flack reflected that he had swum in Bali pools with contacts in many times and had never seriously considered the risk. "Perhaps I didn't know the full risks, but I wish I had," he said.
Practical Advice for Contact Lens Wearers Visiting Bali
The core guidance from eye health professionals is straightforward: contact lenses and water do not mix safely, whether in pools, the ocean, or fresh water. Travelers planning to swim, surf, or spend extended time near water in Bali should consider switching to prescription goggles or daily disposable lenses that are removed before any water activity. Anyone who experiences persistent eye discomfort after swimming should seek medical evaluation promptly rather than attributing symptoms to minor irritation.
Bali's pool culture is a genuine draw for visitors, from resort infinity pools to surf breaks along the southern coast. That appeal is not going away, but it does carry a specific, underappreciated risk for contact lens wearers.
Why It Matters for Hosts
Independent operators running villas, surf camps, or guesthouses with pool access in Bali have a low-cost opportunity here: add a brief note to your guest welcome materials or pre-arrival communication advising contact lens wearers to remove lenses before swimming. A single line in a house-rules document or a small laminated card near the pool could help a guest avoid a serious medical situation. Guests who feel genuinely looked after remember it, and it costs nothing to include.
