Product Insights
The Theo Rectangular Sunglasses by Le 31 deliver true polarization with full UVA/UVB protection at a sub-$20 price, using a lightweight plastic frame and TAC lenses—though the lenses may cause peripheral distortion and a warm tint, and the lack of spring hinges means the temples may loosen over time. The angular brow bar and rectangular shape offset round and oval faces, while the two-color lineup includes a rare yellow option that combines bold style with functional UV coverage, all backed by Simons-owned brand credibility in affordable design.
Verified claims
- Polarization & UV
- True polarization with full UV protection cuts glare for driving and water.
- UV protection
- The lenses provide 100% UV protection, covering both UVA and UVB rays; the product is not explicitly labeled UV400, though eye health experts consider 100% UV protection equivalent to UV400 coverage.
- Lens material
- The lenses are likely TAC plastic, which is lighter than glass but typically shows more peripheral distortion and a warmer color cast than higher-priced polycarbonate or glass lenses; price is $19.99.
- Hinges
- Temple arms have no spring hinge, so they may loosen over time and require adjustment.
- Face shape
- Angular brow bar and corners offset round and oval face shapes.
- Fashion trend
- 1990s minimalist revival meets Le 31's affordable design credibility.
- Frame comfort
- Lightweight plastic frame enables all-day wear for extended styling.
- Color
- Two-color lineup pairs neutral black with a rare, trendy yellow option.
- Value
- Available in a bold golden yellow frame as well as black, both with polarized lenses and 100% UV protection.
- Materials
- Plastic frame and TAC lenses: no spring hinges, possible peripheral distortion.
- Price comparison
- Le 31's Simons-designed polarized UV at $19.99 undercuts high-street by $10+.
- Style
- Black frame versatile; golden yellow rare; shape suits round/oval faces.
- Styling versatility
- Black rectangular frame integrates with monochrome, tailoring, and denim; its angular shape balances round and oval face shapes.
- Brand credibility
- Le 31 is a Simons-owned brand that brings trend-aware design to the sub-$20 category.
- Sub-$20 polarized value
- At $19.99 CAD, the Theo offers polarized lenses and 100% UV protection while most brands in this price range provide only tinted, non-polarized lenses; third-party polarized options typically start around $40.
