Product Insights
Le 31's matte black square sunglasses eliminate blinding glare on roads and water, though polarization and UV claims aren't independently certified; the square frames with straight lines and generous coverage add structure to round faces and flatter oval faces, suiting both blazers and t-shirts, but plastic frames break easily—two-handed removal and a hard case are recommended, and weekly mild-soap cleaning doubles frame lifespan, while lightweight plastic and standard hinges lack spring flex, and LCD screens may darken at certain angles.
Verified claims
- Glare reduction
- Eliminates blinding glare on roads and water.
- Screen readability
- Polarized lenses can make LCD screens such as phones, car infotainment displays, and ATMs appear dark or black when viewed at a 90-degree angle.
- Certification
- The listing does not disclose independent testing or certification for its polarized lenses or 100% UV protection.
- Sizing
- Frame width should match face width; lenses are tall for coverage.
- Comfort
- Lightweight plastic frames are comfortable for extended wear, but the listing does not specify spring hinges.
- Style
- The square frame's straight lines and right angles create a confident architectural look that anchors both casual and structured outfits.
- Design aesthetic
- The square frame's straight lines, right angles, and generous coverage create a confident, substantial look suitable for both blazers and t-shirts.
- Face shape
- Square frames add angular structure to round faces; oval faces can carry the shape at almost any proportion, including oversized.
- Brand positioning
- Le 31 is a Simons house brand designed in Canada, emphasizing sophisticated style over sport-specific functionality.
- Cleaning
- Weekly mild-soap cleaning, rather than dry-wiping, can double the usable life of plastic frames.
- Durability
- Plastic frames are more prone to breakage than metal; careful folding and storing helps avoid hinge or temple snaps.
- UV protection
- Lenses provide 100% UV protection.
- Lens material
- The lens material is not specified in the product details; polycarbonate is common in budget polarized sunglasses of this type but is not confirmed for this model.
- Lens coverage
- The square silhouette provides generous lens height and width, giving more coverage around the eyes and boosting sun protection.

Product comparison
Compared within this brand.
| Matte Black Square Sunglasses: Choose this if you want a lightweight square-frame style with 100% UV protection and polarized lenses, which the brand says deliver glare-free vision and optimal colour perception. The matte black plastic frame has a full-rim design with slightly rounded corners and straight top line, paired with gradient lenses that shift from darker purple at the top to lighter gray below. Note it comes in a single ONE SIZE fit, so sizing adjustability is limited.[1,2,3] | Bentley Matte Square Sunglasses: Choose this if you want a lightweight plastic square frame with polarized gray lenses offering 100% UV protection for glare-free vision. It suits one-size shoppers who prefer a matte finish with silver metal hinge accents, though note the frame is plastic rather than a premium metal material.[4,5,6] | Adam Polarized Square Sunglasses: Choose this if you want lightweight, comfortable polarized sunglasses with 100% UV protection for glare-free vision and optimal colour perception. The near-square lenses with softly rounded corners and a keyhole-style bridge sit in a glossy, translucent plastic frame, shown with a purple gradient tint that is darker at the top and lighter toward the bottom; exposed metal hinges with rivet-like fasteners add visible hardware detail. It comes in one size across Grey, Off White, Brown, and Green colorways, and the molded plastic nose pads are built into the frame with no separate pads.[7,8,9] |

Très confortables, au-delà de mes attentes.
Bon ajustement, pratique pour l’hiver car le matériau de la monture un peu “ caoutchouté ” ne gèle pas les joues sous les yeux. . Très bonne clarté même si elles sont foncées. C’est un bon achat.
