I love my Guard Dog (Evader 1) Goggles http://www.guard-dogs.com/, You can change out the lenses for day/night and the now offer a auto tinting lens. They have several models and a size chart (for what eye glasses they fit over) on the website.

 

Rx'd HD goggles, light transitioning... Worked for me, and well! Ordered from the dealer, took in a copy of my vision rx and I received them in less than two weeks via FedEx to the house. Nice.

 

I find that a flip shield on my half helmet works great for short runs, especially in the hot humid summer weather. But, turbulence is still a problem behind a shield and/or glasses. I prefer a full face for long runs.

 

I'm in the same boat. For the cost, I'll probably get something like these.....

You can get prescription, tinted, bi-focals for $99.00, frame is free. I'm just curious about the wrap around lenses and clarity in the wrap.

 

I ended up getting these from an ebay store - they work very well for my glasses and have interchangeable clear / dark lenses.

I use the emgo over the glasses goggles... but only if it is raining. I have prescription goggles one pair clear and one pair shades.. when it is raining I put these on .. over the top of the others. These work very well over the top of glasses. they sit nicely and don't block peripheral vision.

I have tried 3 or 4 different kinds of over the glasses goggles and just hated them. I finally bought a pair of prescription riding glasses and it's the best deal all around.

 

Guard dogs worked pretty well for the first year I had them. I didn't know the foam had broken down til my SS1k this spring, I dumped about 2 teaspoons of water every gas stop (rained the whole 2,300 miles out and back).

Tried Revision Bullet Ant w/ the RX adapter. Blocks side vision really badly and takes on water if you get hit from the side. Keeping them for mountaineering and still love the Sawfly glasses.

After 9000 miles of touring this year, 40% in the rain I give up. I bought an Arai Vector helmet and now I don't care what the weather does...

 

I have been in and out of contacts for years. Kept going back to glasses because I needed the correction for reading close up stuff while wearing contacts. Had a really small wire frame pair of glasses made with my bifocal prescription. Now almost any wrap around sunglasses go over them or any cheap small goggles.
