Just sayin... I noticed that people flew with their sunglasses and didn't also have their smoke visor (for those I flew with I can confirm they never pulled the smoke down)... for those I'd see fly in/out of a hospital, maybe they used both in flight but even when landing or taking off on a sunny day when I'd see them on the helipad their smoke visor wasn't always dow.
Just made me scratch my head.
Less earcup seal (noise) and definitely uncomfortable in comparison to no glasses; and I used to fly with prescription aviators (issued flat side frames) when I flew in the Army.
