Product Insights
Le 31's Frank Square Sunglasses, exclusive to Simons since 1840, combine polarized glare reduction with 100% UV400 protection in a hybrid frame (plastic temples, metal front) that resists sweat, impact, and corrosion while allowing manual fit adjustment. Priced at 29 CAD, they offer all-day comfort through weight-shifting temples, enhance color perception, and reduce cataract risk—all in a green-grey standard tint (not mirrored or brown).

- Exclusivity
- Only available at Simons, not sold at other retailers.
- Design
- Designed in Canada by Simons' in-house team for a trend-aware square silhouette.
- Lens tint
- The Green variant features green-tinted lenses; the exact shade is not confirmed as dark grey, brown, or mirrored.
- Driving suitability
- The polarized lenses reduce harsh reflections from wet pavement, other car bodies, and dashboard glare, making these sunglasses a functional driving companion when paired with UV400 protection.
- Polarization verification
- The polarization can be verified at home by holding the lenses in front of an LCD screen and rotating them slowly; the screen dims or blacks out at certain angles because the lenses filter polarized light.

Everyday sun protection
Le 31's Frank square sunglasses are designed for wear in sunny conditions, with lenses that the retailer states provide 100% UV protection. The same '100% UV Protection' phrase appears printed on the interior of the left temple. A simple, versatile style for daily outings, commutes, and time outdoors.[1,2]
Glare-free vision with polarized lenses
Wear these square sunglasses when bright glare makes it hard to see clearly — the polarized lenses are designed by Le 31 for glare-free vision and optimal colour perception. This is the merchant's stated intent for the lenses rather than a reported result.[1]
Product comparison
Compared within this brand.
| Frank Square Sunglasses: Choose this if you want everyday polarized sunglasses with 100% UV protection, designed to deliver glare-free vision and optimal colour perception. The lightweight metal-and-plastic frame has a glossy black full-rim front with slightly rounded corners, grey-tinted plastic lenses, and metallic temples with curved black tips, and it comes in one size in Black or Green. Note the molded nose pads are shallow and continuous with the frame, so fit preference may matter.[1,2] | Adam Polarized Square Sunglasses: Choose this if you want polarized lenses with 100% UV protection in a square, near-silhouette style — the lightweight plastic frame is described as light and comfortable, with a clear transparent finish, purple gradient lenses, and a keyhole bridge. It comes in one size only, and the nose pads are molded into the frame rather than separate pads, which may matter if you prefer adjustable fit hardware. Other colorways include Grey, Off White, Brown, and Green.[3,4,5] | Reid Oversized Square Sunglasses: Choose these if you want lightweight, comfortable plastic sunglasses with polarized lenses for glare-free vision and full UV protection, in a thick square frame with a matte dark finish, small metal rivet accents, and a patterned blue-green inner temple, available in Black, Charcoal, Brown, or Green in one size. Note that one reviewer found the fit regular-sized rather than the bold oversized look the name suggests, and the pair is made in China, which was not prominently disclosed and disappointed one buyer.[6,7,8] |
