No dryness. That only happens after a night of boozing and having left them in until the sun begins to rise the next day.Dryness ??? That was the 'old' complaint ... even later in the airlines. Mebbe contacts are more 'juicy' today ... ???
Supposedly current contact designs allow your eyes to "breathe" better by allowing more oxygen through - At least that's what their marketing would have me believe. Like I said, I've had no issues so I'm inclined to believe them. That being said, our flights in the T-45 don't last more than 1.5 hrs, so who knows what would happen if up at altitude for several hours.
