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.
- Design details
- Dark tint doesn't affect UV safety; metal trim needs wipe-down to avoid tarnish.
- Frame longevity
- Fixed hinges and propionate rims need care to avoid loosening and cracking.

Deep Research
What 100% UV protection actually means
- The dark tint on the Roy Rounded Sunglasses reduces visible brightness but plays no role in UV protection; without the UV claim, dark lenses would actually increase retinal UV damage by dilating the pupil, making the 100% UV block the essential safety feature, not the tint.
- Labeled '100% UV protection,' these lenses are functionally UV400-rated — they absorb all ultraviolet light up to 400 nm, a band that spans the full spectrum of solar UVA (315–400 nm) and UVB (280–315 nm), meaning no meaningful UV radiation reaches the eye.
- The ANSI Z80.3 standard for non-prescription sunglasses requires at least 99% UVB and 95% UVA blocking for general purpose, so a '100% UV protection' claim typically exceeds these minimums by blocking 99–100% of both UVA and UVB through 400 nm.
- UV blocking is not a premium feature — the absorbing compounds are mixed into the lens polymer during manufacturing for negligible cost, so a $20 frame like this can deliver the same spectral blocking as a $200 pair, provided the manufacturer certifies to ANSI or ISO standards.
Metal and plastic frame longevity and comfort
- Budget plastic rims are typically injection-molded from propionate rather than laminated acetate, making them more susceptible to cracking under stress and embrittlement from UV exposure over years of use; avoiding heat and flexing the rims during lens cleaning reduces crack risk.
- The metal bridge and temples pair a nickel-plated alloy with plastic rims, a combination prone to developing green copper-oxide tarnish from sweat contact—wiping the frame after wear and storing it in a case slows oxidation and keeps the metal looking clean.
- At $20 CAD, sunglasses commonly use fixed rather than spring hinges, meaning the screws can back out with repeated temple folding—applying a tiny drop of threadlocker to the hinge screws after purchase prevents the need for frequent retightening.
- Plastic rims expand and contract with temperature changes more than the polycarbonate lenses, so in cold weather the rims grip tighter, while in heat they can loosen—if a lens pops out, gently warming the rim with a hairdryer allows easy reinsertion without forcing.
