I have worn guard dogs for over a year. I wear them everyday as I walk my dog, go on holidays, go shopping, whatever. They protect my eyes from the wind. The smoked aren't great as sunglasses but with a peaked ballcap they work well. I use electric black tape to cover the top holes on very windy days. Other wise they do the trick. Not the most flattering but hey if you want to continue with your activities they are a must. Not great for driving, no peripheral vision. Fit well over my glasses.
