I have seen a new style recently that I liked: it's basically an inner tube around the dog's neck. It's nice because it doesn't require any kind of tie that could catch on something, and it doesn't block peripheral vision. I believe they are sold at PetCo, etc.

. . . .

Sorry, after reading your post more carefully, I'm not sure that an inner tube collar-type would prevent a dog from scratching his eyes. I guess it might if it were big enough. However, I think they are more designed to prevent dogs from tearing out stitches.
