TL;DR: Prefer new Wayfarers for fit, durable for active use, reasonable lens replacement cost, effective lens gradient.Reviewing sunglasses is subjective, but I've been particularly pleased with the fit of the new Wayfarer style, which is slightly smaller than the original and suits my face better. I use them for both casual wear and during outdoor activities like running and coaching. This is my second pair; my first pair, which I've had for two years, is still in good shape despite cracked lenses (due to my own mishap).I appreciated the first pair enough to buy a backup while looking into lens repair options. The polarized replacement lenses from Luxottica are quite affordable at around $59, shipped. The crystal/glass lenses with a blue to brown fade are practical for driving, providing darker coverage at the top and lighter at the bottom for easy dashboard viewing.These sunglasses have endured rough handling, including being tossed in a backpack, dropped, and even stepped on, yet they still retain their shape and fit. The tortoise frame has a nice matte finish, and the hinges have remained firm, albeit slightly looser, over time. The glass lenses offer clear visibility and excellent polarization, showing minimal scratches even after extensive use.Overall, I'm satisfied with my initial purchase and reassured by having a backup. Their popularity also gives me confidence in the availability of replacement lenses in the future.
