Innocent mistake on long flight could have devastating consequences for travelers

An everyday habit during a long-haul flight could have painful consequences for certain travelers — with a recent case highlighting some serious dangers. 

The dry air inside an airplane cabin, combined with hours spent wearing contact lenses during a long travel day, can leave the lenses with less moisture and eyes feeling increasingly uncomfortable, experts say.

In some cases, irritation or damage to the surface of the eye can lead to more serious problems.
