I learned of these from some of my tactical buddies in the Army.
The SG-1 from Wiley X (
http://www.wileyx.com) are hands-down the BEST goggles I have ever used for long distance (greater than 1000 mile trips) riding, commuting, and tactical/shooting needs.
I am 6'5" tall and I have been street riding since 1972. I use them on my '84 Softail, which doesn't have a windshield, my 100th Anniversary Road King with it's King-Size windshield, and now with my 110th Anniversary CVO with it's stock windshield.
I don't wear vision correction glasses so I don't know what it is like to wear anything else for long periods of time, but I have worn my SG-1's for as long as 12 hours per day of riding in hot, cold, snow, and rain without any type of fatigue. The only problem I ever had was when I first bought them, I kept the strap too tight and I dug them in to my face which made the contact points uncomfortable. A quick adjustment of the strap now and then and I am golden.
I can turn my head to any angle, including looking behind me in both directions at 80+ mph on the Softail without so much as a nudge.
They take hard impacts (my experience with rocks, shrapnel, etc.).
You can change the lenses for changing needs (many choices).
They fit excellent once you find the right strap tension.
The only non-goggle eyewear I have found that block wind and debris surprisingly well is the Ray Ban Wayfarer. Even the knock-offs and clones work, but I like a quality lens as light filtration is more important than style or other function.
