Soft case, not universal, not worth the price
Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters, Color: Dark Tort/Green, Polarization Type: Non-Polarized, Lens Width: 50 Millimeters
I didn't pay for these, but priced at more than $70, I wanted to try them. The description is confusing if not misleading, stating "Quay merges music and fashion to create trend-forward designer eyewear for any moment or mood." Given the exorbitant price for a brand I never heard of (e.g., Raybans may be overpriced, but they come with a 24 month warranty and it's a brand that's been around a long time), I thought that these shades played music. How else are ordinary $10 sunglasses priced at nearly $100? How do they "merge music"??? Answer: they don't. They're sunglasses.
They're also not "Designed for a universal fit," because they're way too big for me, and I have a normal-sized head, and I have bought many pairs of sunglasses and nearly all of them fit just fine. In fact, this is only the second time I ever tried on a pair and they were too large, but the other time, those sunglasses, which were a lot more stylish than these, cost around $20.
The case is soft, which is ok, I guess. Some people prefer it but to me, if a case will not provide any protection from being crushed, e.g., sat upon, or had something heavy put on top, then it's not a very good case. They also included a nice lens cloth.

Impressive lenses quality for polarizing that works
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
As much quality of polarized glasses that you can get for the value here with actively polarizing glasses that not only block bright sunlight but dramatically reduces glare and bright rays on light surfaces even compared to some "better" sunglasses that aren't polarized. You really have to test them yourself to see, and if you like the lenses, you'll like this! The lenses are dark grey, so they keep the true color of grass, trees, sky, everything, just with dimming effects which I prefer, it's not a massive change changing colors, it's more natural to me.
The quality & style is high with the whole glasses feeling sturdy and smooth as you open them and put them on. It's made with some basic plastic frames, they have a nice softer texture that's almost silicone feeling, so they feel great & soft but also it helps support sitting on the nose and ears. Perfect fit (I'm a man, average head I would say lol) I haven't noticed any sliding around at all with these!
Lenses are made from PC with polarizing. They feel thick, sturdy, and stay clean. I have only noticed one fingerprint so far after wearing them for 2 weeks. It definitely is a weekender look and case build. The edges sit a little further away from the skin so depending on the angle there can be a little glare and reflections of your eyes cheeks in the lenses. If I had to choose a part I don't like the most that would be it. Pretty glarey on the inside. On the outside, it's reflective to any light so lots of sunlight will reflect off and hide your eyes which I like.
Aesthetics, usability, quality for the value, all make this stand out to me and I would definitely be packing this when I'll be in a lot of light, even for driving with the anti-reflection polarized lenses. Very impressed with this pair. I would like the sides to be closer but I guess I would have to get a different style, these are weekender, so all in all I'm a big fan!

Neat design with high quality lenses
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
These Quay sunglasses combine a unique bridge design with a sleek, modern style that stands out. At first, I wasn’t sure if I’d like the way they sat on my nose, but after wearing them, I found the look and fit to be both flattering and comfortable.
The frames are lightweight yet sturdy enough for daily use, and the fit is secure without slipping during regular activity. The polarized lenses are excellent optical quality, reducing glare effectively while staying distortion-free, which makes them great for driving and outdoor wear. I’ve worn them for several hours at a time with no discomfort.
For the price, these sunglasses strike a nice balance between fashion and function, offering a high-quality lens and a stylish frame at a reasonable value.

Bold Look with Good Sun Protection, Slightly Big Fit
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
I picked up the QUAY Weekender sunglasses in matte black mainly for everyday wear, and they definitely make a statement. The oversized rounded shape stands out and gives a modern, slightly edgy look. The lenses provide solid UV protection, and I’ve found them comfortable to wear for long stretches without eye strain.
They are on the larger side, though. If you have a smaller face, they might feel a bit oversized or slide down slightly. The frames feel lightweight but still sturdy enough for regular use. Overall, they’re a stylish pair of shades that balance fashion and function well, especially if you like a bold, oversized design.

Well Made, Fits Well, Comfortable to Wear, Stylish, Good Value
Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters, Color: Matte Black/Black Polarizedarized, Polarization Type: Polarized, Lens Width: 50 Millimeters
These sunglasses are a masterclass in understated elegance, proving that superior quality and timeless design can come in a perfectly proportioned package. They are an exceptional choice for those who value both form and function in their eyewear.
The round "Weekender" style is a timeless classic that exudes a sense of both vintage cool and modern sophistication. Unlike the current trend of oversized frames, these sunglasses are a refreshing alternative, with a size that provides a perfect, unobtrusive fit. The frame feels sturdy and well-balanced, a testament to the excellent quality of the materials and craftsmanship. Their sleek appearance is versatile enough to be worn with a casual outfit or to an upscale event.
The optical performance is truly outstanding. The polarized lenses are a key feature, as they dramatically reduce glare from reflective surfaces like water, pavement, and car windows, which improves visual clarity and significantly reduces eye strain. Coupled with comprehensive UV protection, the lenses offer crucial eye health benefits without compromising on style. The sunglasses are also incredibly comfortable to wear, with a lightweight feel and a great fit that allows for hours of wear without any discomfort.
At a price point of $75, these sunglasses offer an unbeatable value. The combination of high-end optical features, classic style, and premium build quality is typically found in products at a much higher price. The thoughtful inclusion of a soft squeeze pouch case—which is both sleek and highly practical—and a cleansing cloth further enhances the overall value.
For their superior optical performance, sophisticated design, and exceptional value, these sunglasses are a highly recommended accessory. They are a functional and fashionable piece that you'll be happy to wear on any occasion, and they stand as a testament to the fact that you don't need to overspend to get a high-quality product.
