I don't know why I'm even looking at this drop. I have too many gunnar glasses. I like the intercept frame, and over some time I've gotten 5 different pairs of those frames in different colors with different lenses; onyx work-play, onyx crystalline, onyx circ, and two outdoor lens, one with a raven frame, and one with dark ale 24k. Those last two were part of buy-one-get-one promos, at least partially absolving myself of the guilt of owning 3 pairs of sunglasses. The work-play are the most versatile, as they should be equivalent to amber lenses indoors, and gray sunglasses outdoors in terms of blue light transmission, though I don't believe they block as much of the rest of visible light as the gray lenses. Of the pairs of gray lens sunglasses I have, I do like the feel of the dark ale frame material, and the 24k series hinge hardware move with less resistance. The other pair of outdoor glasses I have are the pair I take with me hiking, as if I had to pick a pair of glasses to fall off of my face down a ravine, that one would leave me least bummed out. I don't know how I feel about the Circ lenses (sort of blue sunglasses). The promo information I can find suggests it has the same 90% blue light protection, while claiming to "harness the benefits of good blue" in terms of preserving your circadian rhythm, but I don't really know if I have the problem that claims to correct. The crystalline lenses I got because one of my workspaces is just poorly lit, and even wearing the amber lenses feels like I'm wearing sunglasses at night. I am a little curious about the liquet lens, but that doesn't appear to be an option on this drop so I'm probably safe. But if next time I see a tortoise 24k intercept frame with liquet lenses next drop, I'll probably be filled with further disappointment in my ratio of pairs of gunnars to pairs of eyes. Luckily I don't think they actually make that combination.
