Hello Experts, I'm working in middle east and now is the summer season. I'm planning to buy Oakley sunglasses for my team. However I need technical specification for the different between normal safety glass (Model NTLS 1120; URL; http://mayurindustrial.tradeindia.com/E ... ggles.html ) with Oakley (url; http://uk.oakley.com/products/5240 ) . Appreciate if you all can help me out. Thanks in advance.
