I was particularly interested in these shown in the picture... if you look closely, you'll notice they have "readers"... but not in the bottom of the lenses, rather, on the top! I haven't fished in these yet, but I am intrigued. I do wear a progressive lens with close-range focus at the very bottom of my glasses now, and the problem with that is, when I guide, most of the time I'm looking down. Not just when I'm tying on flies, but also when I'm spotting fish... heck, even walking on a rocky riverbed (looking for snakes). And frankly, the reader lenses on the bottom can be inconvenient, especially when I'm walking along and my feet look fuzzy.
