My Costa 580G (Glass) lens shattered and I needed some replacement lens. Costa stopped making my specific lens so I googled and came across Tajima Direct. I ordered my replacement lens for $99, got a prepaid shipping box, shipped my Costa’s off and had my sunglasses back within several days. I literally can not tell the difference between Costa’s 580G lens and Tajima Direct’s polycarbonate lens. These lens are so clear it’s insane. Not to mention, the customer service, is world class. I emailed Tajima Direct to follow up on my replacement and Jacob literally replied to my email with in minutes! Tajima Direct has a lifetime customer just because of their world class customer service and their best in house lens.
