If you've spent any time browsing SUNGAIT's round sunglasses, you've probably landed on both of these at some point and wondered what actually separates them. They're both round, both vintage-inspired, both under $20 — so what's the real difference?
Here's the honest answer: it's not really about size, even though one is literally named "Small Vintage." The bigger differences come down to frame material, lens proportion, and finish — three things that change how each pair fits and feels a lot more than the name suggests. (Both are currently under $19 on sungait.com, with SGT059 starting from $15.99 and SGT567 from $17.99, so price isn't much of a deciding factor either.)
The Numbers, Side by Side
| SGT059 (Small Vintage) | SGT567 (Vintage Round) | |
|---|---|---|
| Frame material | Full metal | Lightweight acetate |
| Lens height | 49mm | 44mm |
| Lens width | 54mm | 55mm |
| Nose bridge | 20mm | 15mm (keyhole) |
| Temple length | 143mm | 137mm |
| Frame length | 144mm | 139mm |
| Price | From $15.99 | From $17.99 |
Frame Material: Metal vs. Acetate
This is the difference that matters most day to day. SGT059 uses a full metal frame with a matte, frosted finish — it has that classic wire-rim vintage look, feels a little more substantial on the face, and holds its shape well over time since metal doesn't warp the way plastic can in heat.
SGT567 uses a lightweight acetate frame, which is softer to the touch, comes in a wider range of finishes (matte, glossy, tortoise, gradient tones), and tends to feel a bit more forgiving if it gets bumped or sat on. Acetate also takes color and pattern better, which is why SGT567 shows up in more color variations than SGT059.
If you like the delicate, wire-frame vintage look — think classic 60s round glasses — SGT059's metal frame gets you there. If you want more finish and color options, or a slightly softer everyday feel, acetate is the way to go.
Lens Shape: Tall and Round vs. Wide and Rounded
This is the part the spec sheet actually gives away. SGT059's lens is noticeably taller relative to its width (49mm height vs. 54mm width — closer to a true circle), which gives it that classic, almost owlish round-lens look. SGT567's lens is shorter and a bit wider (44mm height vs. 55mm width), which reads as more of a rounded-square shape — still round, but with slightly more visual width across the face.
If you want the most "textbook vintage round" look, SGT059's taller lens gets closer to that. If you prefer round sunglasses that sit a bit more horizontally and feel less exaggerated, SGT567's proportions are the gentler version of the same idea.
Nose Bridge: Keyhole vs. Standard
SGT567 uses a keyhole nose bridge — that little cutout at the top center of the lenses, styled after 1930s-40s eyewear. It's mostly aesthetic at this point, though some people find it sits slightly differently on the nose than a standard bridge. SGT059 uses a standard adjustable nose bridge, which tends to be the safer, more universally comfortable option if you're not sure how a keyhole bridge will feel on you.
Which One Should You Get?
Honestly, both are safe bets — this isn't a case of one being clearly better. It comes down to what you're actually going for:
- Want the classic wire-frame, taller round lens look? Go with SGT059 Small Vintage Round Sunglasses.
- Want more color and finish options, a keyhole bridge detail, and a slightly softer acetate feel? Go with SGT567 Vintage Round Sunglasses.
- Can't decide? Both are polarized, UV400-rated, and priced close enough that trying one first isn't much of a commitment either way.
FAQ: SGT059 vs SGT567 Vintage Round Sunglasses
Q1: Is SGT059 actually smaller than SGT567?
Not by much, and not in the way the name suggests. SGT059's lens is taller (49mm vs. 44mm), while SGT567's is wider (55mm vs. 54mm). The overall frame length is also slightly longer on SGT059 (144mm vs. 139mm). The "small" in the name refers more to the classic, tighter round silhouette than to the actual measurements.
Q2: Which frame material lasts longer, metal or acetate?
Both hold up well with normal use. Metal (SGT059) resists warping from heat better and keeps its shape long-term, while acetate (SGT567) tends to be more forgiving if it's bent or sat on, since it flexes rather than staying deformed. Neither is a clear winner on durability — it's more about which failure mode you'd rather avoid.
Q3: Are both of these polarized and UV protected?
Yes. Both SGT059 and SGT567 use polarized, UV400-rated lenses that block 100% of UVA/UVB rays — the material and shape differences are purely about fit and style, not sun protection.
Q4: Which one fits smaller faces better?
Neither is dramatically more compact overall, but SGT059's taller, more circular lens can feel a little more contained on a smaller face, while SGT567's wider lens shape may extend slightly further toward the temples. If you have a narrower face, it's worth leaning toward SGT059.
