Product Insights
The Roy Rounded Sunglasses by Le 31 offer UV400 protection for $29, but their non-polarized lenses and plastic-and-metal frame—prone to cracking, tarnish, and loose hinges—require frequent care and after-purchase maintenance.
Verified claims
- UV protection
- UV400 protection blocks all UVA/UVB, independent of tint and polarization.
- Polarization
- Lenses are not polarized.
- Durability
- Frame vulnerable to UV embrittlement, sweat tarnish, and loose hinges.
- Frame material
- Plastic and metal frame: propionate rims crack under stress and expand with heat; alloy tarnishes from sweat.
- Hinge maintenance
- Fixed hinge screws back out; apply threadlocker after purchase.
- Corrosion
- Regular wiping and case storage prevent green tarnish from sweat on metal parts.
- Cost
- At $19.99–$29, the low price reflects non-polarized design, not UV protection compromise.
- Frame longevity
- Fixed hinges and propionate rims need care to avoid loosening and cracking.
- Lens reinsertion
- If a lens pops out after the plastic rims expand in heat, gently warming the rim with a hairdryer lets the lens be reinserted without forcing.
- ANSI UV compliance
- The 100% UV protection claim exceeds the ANSI Z80.3 general-purpose minimums of 99% UVB and 95% UVA blocking by covering 99–100% of both UVA and UVB through 400 nm.
- UV protection value
- UV blocking is not a premium feature: the absorbing compounds are mixed into the lens polymer at negligible cost, so this frame can deliver the same spectral blocking as a much more expensive pair if the manufacturer certifies to ANSI or ISO standards.

Product comparison
Compared within this brand.
| Roy Rounded Sunglasses: Choose this if you want a classic glossy black, round full-rim pair with dark gray smoke-tinted lenses and 100% UV protection. The lightweight metal-and-plastic frame is described as comfortable, with subtle silver rivet and temple-line accents, and it comes in a single ONE SIZE in Black. Note the fit isn't adjustable, so a one-size-only option may not suit everyone.[1,2] | Kurt Translucent Rounded Sunglasses: Choose this if you want lightweight, comfortable plastic sunglasses with polarized lenses that the retailer says deliver glare-free vision, optimal colour perception, and 100% UV protection. This rounded, full-rim style comes in a glossy translucent dark finish with a keyhole bridge, metal rivet accents, straight temples with curved tips, and grey-blue tinted plastic lenses, offered in one size (with White, Brown, and Green colorways also listed). Note there are no separate nose pads, which may matter if you prefer adjustable nose fit.[3,4,5] | Terry Round Sunglasses: Choose this if you want a retro-styled pair of round sunglasses with an ultra-thin black metal frame, light brown tinted lenses, and 100% UV protection. Adjustable transparent silicone nose pads and thin metal temples with black plastic tips add comfort details, and it comes in one size in Black or Green. Note the fit is a single one-size option, so sizing flexibility is limited.[6,7,8] |
