 A lot of us wish we'd get around in two and a half, three hours, maybe on some days. But, you know, on Sunday morning, it could be a five-hour round. And that's where the nylon comes into play as well. You know, if you have a warm polarized sunglasses for 10, 12 hours and get a headache, you know, it's because they're not as optically pure as a glass or nylon. So these are things, you wear this for 12 hours, there's going to be no headache. You know, your eyes are going to be relaxed the entire time.
