So long as the Frisbee is near by she doesn't care the least bit. I think she's even starting to recognize that when the doggles come out that means it's time to throw the Frisbee and she's puuuuumped.

My last pup was blind, so would run into things that could poke her in the eyes while out on walks. We got a set of Doggles and while it took some getting used to, she ended up tolerating them well. Depends on the dog and the training!
