Old word for glasses, I personally have light-sensitive eyes so I even went as far as order some Intellitec flight-glasses from USA, Shields Eyewear I think it was, the normal cheap one was sold out but they has some red-tinted with red cord made for NASA left so I got those instead, I use them everyday now. Someone claimed on their site he'd pulled 10g's with them in his plane without them moving, hehe well no kidding, it depends on what direction those come from I guess but they are nice, except hard to put on with a cord instead of frame (to relæieve pressure from a headset as opposed to metal frames pressed into your head).
That could actually be an interesting question, what glasses to pilots use? Ray Ban Aviator's or more special/new ones like me?
