Product Insights
Le 31's Jean Rounded Sunglasses combine polarized lenses that block horizontal glare and reduce luminance to 3–16% of non-polarized levels, enhancing color saturation and object sharpness while revealing underwater obstacles and wet road hazards. The round frame with thin silver metal rims and dark gray tinted lenses flatters oval, narrow, heart, and square faces. At 29 CAD, this exclusive Canadian design by Simons requires careful lens and frame care—rinsing lenses before wiping, avoiding harsh chemicals, and storing in a hard case to prevent corrosion—offering a refined silhouette that balances glare reduction with delicate maintenance.
- Glare reduction
Blocks horizontal glare to reduce eye strain and sharpen details.
Why this is supported
Polarized lenses work by filtering horizontally reflected light.
Polarized lenses block glare or horizontal light while vertical light passes through them.
aao.orgThis reduces the luminance of road glare to just a fraction of non-polarized levels: a 2023 study found that
the luminance perceived with polarized sunglasses is just a fraction of the one perceived with non-polarized ones: the fraction perceived goes from 3% to 16%
optogrid.comThis dramatically cuts blinding reflections, and as Harvard Health notes, wearing polarized glasses
minimizes glare, reduces eye strain, and can help you make out details more clearly

Reveals underwater obstacles and wet road hazards by cutting surface glare.

Reduces eyestrain and helps you see below the surface of the water.

- Color sharpness
Enhances color saturation and object sharpness for better visual clarity.
Why this is supported
A study on road athletes found that polarized lens wearers perceive
more saturated colors, sharper objects, and discontinuities on the road

- Face compatibility
Round frame flatters oval, narrow, heart, and square faces.
Why this is supported
The Jean's round silhouette is recommended across multiple face shapes.
An oval face is the most versatile face shape when it comes to sunglasses.
roav-eyewear.comFor narrow faces,
Need sunglasses for a narrow face? Round models are particularly suited.
roav-eyewear.comHeart-shaped faces also work well:
For a heart-shaped face (wide forehead, narrow chin), round sunglasses work surprisingly well.
roav-eyewear.comOn square and rectangular faces, the classic advice is that round shapes soften angular lines:
The soft, round shapes of the frame soften the angular lines of your face and create a pleasant visual balance.
roav-eyewear.comHowever, the Jean's specific design relies on its dark lens tint to give the thin metal rim enough visual weight. A guide notes that
darker or richly tinted lenses in a round shape add a bit more visual weight up front, which reads as intentional rather than accidental on a defined jawline.
kraywoods.comThis makes the Jean a refined alternative to bolder acetate rounds, as described:
The Jean's lightweight metal frame gives its round silhouette a more understated presence than thick acetate rounds — on angular faces this means a refined softening rather than a heavy statement, and the darker tint of sunglass lenses adds just enough visual mass to prevent the thin rim from disappearing on a defined jawline.
Which face shapes suit round sunglasses — rim_weight_lens_tint- Frame care
Wipe metal frames after each wear and store in a hard case to prevent corrosion and warping.
Why this is supported
Sweat and salt residues accelerate corrosion on metal frames, especially at nose pads and hinges. One source explains:
Metal reacts to moisture, sweat, skin oils, and even the chemicals in your skincare products. Lower-quality metals or uncoated frames may start to corrode, showing signs of discoloration, flaking, or pitting.
blakspecs.comTo prevent this, wipe the frame after each wear and store it dry. Additionally, storing the frame in a hard case protects against micro-bends:
Placing glasses lens-down, tossing them into bags without a case, or exposing them to high heat (like in a hot car) can all lead to accelerated wear and damage.
blakspecs.comBoth practices extend the lifespan of a metal frame like the Jean.
- Lens care
Rinse polarized lenses before wiping, use lotion-free soap, avoid alcohol/ammonia/vinegar, and use only a clean microfiber cloth.
Why this is supported
Start by rinsing lenses with water to remove abrasive particles before wiping; a source explains:
The moment you wipe without rinsing first, you are dragging those particles across the lens under pressure. It is functionally the same as rubbing the lens with fine sandpaper.
hewore.comOnly lotion-free dish soap should be used for deep cleaning, because soaps with moisturizers leave a film:
Soaps with moisturizers, fragrance additives, or any other enrichment leave a film on the lens that is difficult to remove and can degrade coatings.
hewore.comAvoid alcohol, ammonia, and vinegar. Research indicates
Isopropyl alcohol (rubbing alcohol) | Dissolves AR coating bonding layer, degrades polarized films
z-clear.comand
Vinegar | Acidic — degrades oleophobic coating over time
z-clear.comFinally, use only a clean microfiber cloth stored in a sealed pouch, as paper products are abrasive:
Paper products — tissues, napkins, paper towels — are made from wood pulp, which is inherently abrasive. Even soft tissue leaves micro-scratches on optical coatings.
hewore.comThese practices keep polarized lenses scratch-free and preserve their performance.

- Frame design
Thin silver metal rims and dark gray tinted lenses for a refined silhouette
Why this is supported
The frame design combines thin metal rims with dark lens tint. The tint ensures the round silhouette reads as deliberate:
darker or richly tinted lenses in a round shape add a bit more visual weight up front, which reads as intentional rather than accidental on a defined jawline
kraywoods.comThis prevents the rims from seeming lost, as
- Polarized lenses
Reduces glare to 3–16% of non-polarized luminance and aids water visibility
Why this is supported
The polarized lenses offer a measurable performance benefit:
the luminance perceived with polarized sunglasses is just a fraction of the one perceived with non-polarized ones: the fraction perceived goes from 3% to 16%
