Contact Lens Wearers Warned of Risks on Long Flights

Wearing contact lenses during long flights could lead to serious eye complications, including corneal ulcers, due to the dry air within airplane cabins, according to experts. One traveler recently experienced significant vision loss after wearing contact lenses for an 11-hour flight, followed by showering and swimming while they were still in.

This individual was later diagnosed with a corneal ulcer and, after weeks of treatment, was left with a scar that continues to affect her vision. Optometrists explain that the low humidity in airplane cabins can dry out contact lenses, leading to eye irritation, a gritty sensation, and blurred vision.

Valerie Kattouf, an optometrist, noted that sleeping with contact lenses on long flights exacerbates these risks. As a lens loses moisture, it can adhere more tightly to the eye, potentially damaging the corneal epithelium upon removal. This can cause irritation and affect vision.

To mitigate these risks, eye care professionals recommend that travelers bring a pair of prescription glasses to wear during long flights. Alternatively, individuals who start their journey with contact lenses can switch to glasses before sleeping or at some point during the flight. For those who continue to wear contacts, using single-use vials of artificial tears can provide additional lubrication.

Online discussions among travelers reveal a common practice of opting for glasses on extended trips to avoid the discomfort and potential issues associated with wearing contacts in the dry cabin environment. Some users have shared experiences of severe dry eyes even after using eye drops.
