I like my new Oakley M Frames I think these glasses provide good protection from the sun and impacts. Since using them I have had no problems, however, I have found they take a little bit to get used too. The clarity is amazing and I think it appears that since everything is so clear that you feel like more sun is coming in through the lenses so I found myself squinting a little, but after a week or two all was good. I also tried to purchase my flack Jackets through amazon, but amazon wouldnt let me due to pathetic restrictions - go figure let me purchase one pair but not another I really hate amazon, Australia is not a third world country!
