Curt Smariowrote a review of Costa Permit Polarized Sunglasses - Costa 580 Glass Lens on March 28, 2012
Bought a pair of Cost Del Mar sunglasses with 400 polarized glass lenses. The literature speaks of how a steel ball is dropped ten times from over four feet and the lens will not be damaged. My experience with the new glasses is I dropped them on the kitchen floor from less than four feet and they shattered. I am just glad they were not on my face when that happened. I sent them in and they would not warranty. replacement of lens was quoted more than price of glasses new. I have had five pairs of Maui Jims, many revo's etc. This has never happened when they were dropped. No thanks Costa.
