backstroke ~ bright sun protection ~ goggles

I swam 2000 yards backstroke yesterday, not wearing goggles, afterwards was dark red in the face and figured this wasn't good for my eyes. However, none of my 3 pair of goggles allow enough peripheral vision to see well. What kind of goggles have you found to give you the widest vision for backstroke? Might these work well? 10495 They have 180 degree vision, but still have the gasket that blocks vision. I was about to order them, then got the great idea last night to use regular sunglasses 10496and will try them next week. Let me know what goggles you feel would work best for the backstroke. I won't be doing any flip turns or diving with these.
