Wally World specials, since i break allmost every pair that i have had.
I have owned ray ban, Oakleys and a few other high price sunglass's over the years, and they all break the same. I have very sensitive eyes, and live on the sun (AZ) so i do wear sunglass's everyday of the year, and have not found much diff in the high $ brands, and some for $10-$20. Most plp are paying for the names only. Well anyway thats my .02.
