re: Costas or Oakleys (Posted on 6/20/13 at 6:24 am to Jester)
As one who studies lens quality for a living, Costa's 580 lens is hands down better than Oakley. From what I have found Costa's 400 entry level lens is more similar to Oakley.
For lens quality I like:
1. Maui Jim 2. Costa 580 3. Wiley X 4. Kaenon
Keep in mind this has NOTHING to do with frame style only with lenses. I get all the manufacturers latest and greatest and some of their reps to my camp in Venice once a year to test them against each other. The above are my results.
