Sad to think, how many lives could have turned out differently, if children (and adults) had only know what I’m about to reveal:

You can wear glass and still be a pilot (or even an astronaut)!

I realized this a few years ago when I saw a commercial pilot wearing glasses, but I only “formally” verified it this morning. The exact regulations are complicated though. Different restrictions apply to commercial pilots and to fighter pilots and the rules even vary from airline to airline. But if the correction is not too strong, then it’s certainly no problem. However, with some airlines you may not be color-blind to become a pilot.

If you’re curious then check out the discussions at Yahoo answers (e.g., here or here) or at answerbag (which gives the most details).
