Core 04 Square Sunglasses
The Chimi Core 04 Square Sunglasses (from Chimi's Sweden-designed collection) are acetate-frame sunglasses with dark gray lenses that provide Level 3 UV protection (full UVA/UVB). They measure 45 mm eye width, 24 mm bridge, and 145 mm temples, and come with a rigid case. While users find the frame comfortable and well-made, they note the lenses lack an anti-reflective coating, which can cause glare when the sun is behind the wearer.

Product Insights
The Core 04 Square Sunglasses from CHIMI are entry-level luxury at $220, featuring handcrafted Italian acetate frames and flat CR39 lenses that provide distortion-free, edge-to-edge clarity with 100% UV400 protection and anti-shatter safety, while non-polarization ensures screen readability on phones and car displays—but the flat lenses lack AR coating, creating distracting back reflections in certain lighting.

Product comparison
Compared within this brand.
| Core 04 Square Sunglasses: Choose this if you want a bold, square everyday sunglasses style: a thick glossy black acetate frame with flat dark gray lenses, full UVA and UVB protection, and a Level 3 rating suited to sunny days. The 100% acetate frame is described as light and comfortable, comes in one size (45 mm eye width, 24 mm bridge, 145 mm temples), and includes a rigid designer case. Note it is one-size-only and offered in Black, Taupe, and Green, so the fit depends on whether those dimensions suit your face.[1,2,3,4] | Core 10 Narrow Rectangular Sunglasses: Choose this if you want a light, comfortable acetate frame in a narrow rectangular silhouette with a minimalist, low-slung look—the brand describes its design as minimalist charm with slightly tilted angular lines. The Level 3 (CAT 3) UV protection and scratch-resistant, non-mirrored lenses suit sunny days, and the frame is made from Eastman Acetate Renew, a blend of certified biosourced and recycled materials. Note the lenses are non-polarized, so glare reduction is limited; a rigid designer case and small cleaning cloth are included, and it comes in one size (49 mm eye, 22 mm bridge, 145 mm temple) in Black or Off White.[5,6,7,8,9] | Core 06 Cat-Eye Sunglasses: Choose this if you want a bold, feminine cat-eye look with strong sun protection: the lenses offer complete UVA and UVB protection with a Level 3 rating, and the retailer characterizes them as perfect for sunny days, with high glare reduction and scratch and impact resistance. The frame is a light, comfortable acetate — handcrafted from premium Italian acetate per the listing — in a glossy black cat-eye design with thick frames and flat, uniform dark grey lenses, sized at a 53 mm eye width, 21 mm bridge, and 145 mm temples, in one size with a rigid designer case included. Note the brand states these fit small to medium heads, which may matter if you need a wider fit.[10,11,12,13,14] |

Enthusiastic two-pair owner review of CHIMI sunglasses
I bought two pairs last summer and wear them daily. I LOVE them. They look expensive and the quality is there.

Explanation of AR coating issue causing reflections on CHIMI 04
Unfortunately, if the lenses don't have an AR (anti-reflective) coating on the back this can happen. I find it's only really flat lenses that give me this problem along with certain lighting conditions, ie. the sun at my back. Short of replacing the lenses I'm not sure what else can be done. Sorry, wish I had better news.
