Answer: Contacts
Clues: “Vison” and “Correctors”
Doctors are telling people they should think about not wearing contact lenses on flights. It’s fine for shorter flights and if you don’t plan on sleeping. But on longer flights the air circulating in the cabin is super dry, so the longer you’re exposed to it, the more dried-out your eyes — and contacts — can become. The cabin is also pressurized for the high altitude, which reduces oxygen intake for your eyes. Combined with dryness, a whole host of gruesome problems can arise. Wear glasses if your eyes are already red, irritated or light sensitive, or if you have a pre-existing infection. If you’re already wearing them and notice some dryness, practicing good hygiene by washing your hands can help alleviate symptoms.
