An innocent habit of wearing contact lenses during long-haul flights is emerging as a significant risk, potentially leading to severe eye complications, including permanent vision impairment. The dry, recirculated air within airplane cabins drastically reduces humidity, stripping moisture from contact lenses and causing eyes to feel increasingly dry and uncomfortable. This dehydration, exacerbated by prolonged wear, especially when combined with sleeping on the flight, can lead to irritation and damage to the cornea’s outer layer, the epithelium. In a stark cautionary tale, one traveler experienced a sudden loss of vision after an 11-hour flight where she wore her contacts continuously, even while swimming and showering. She developed a painful corneal ulcer, requiring weeks of treatment and leaving her with a permanent scar that blurs her vision. Optometrists strongly advise travelers to opt for prescription glasses on long flights, or at least switch to glasses before sleeping, to protect eye health and prevent such devastating outcomes. For those who must wear contacts, using single-use artificial tears can offer some lubrication, but glasses remain the safest choice to avoid the painful and potentially vision-altering consequences of extended contact lens wear in the harsh airplane environment.
