Carlos Hexagonal Sunglasses

Le 31's Carlos Hexagonal Sunglasses offer UV400 protection in a lightweight, adjustable metal-plastic frame inspired by 1950s-60s design, fitting oval, round, square, and heart-shaped faces. At a direct-to-consumer price of 29 CAD (sale 19.99 CAD), they deliver Canadian design but trade off polarization for tinted lenses, and require gentle cleaning and rigid storage to prevent scratches and warping.

Face shape

Hexagonal frames are specifically suited to oval, round, square, and heart-shaped faces.

Why this is supported

The research provides specific recommendations for each face shape: for oval faces,

a safe platform for experimenting with geometric framesWhich face shapes suit hexagonal frames — for_oval_faces

; for round faces,

the Carlos’s thin metal frame keeps the geometry prominent without adding visual weightWhich face shapes suit hexagonal frames — for_round_faces

; for square faces,

lightweight frame’s slim profile prevents the heavy-frame lookWhich face shapes suit hexagonal frames — for_square_faces

; and for heart-shaped faces,

creating a visual equilibrium that offsets the typical top-heaviness — the charcoal tint further minimizes any additional bulkWhich face shapes suit hexagonal frames — for_heart_shaped_faces

. These confirm the frame's suitability for these four face shapes.

Comfort

Metal frame is lightweight and adjustable for custom-fit comfort.

Why this is supported

The metal-predominant frame is lighter than typical plastic,

. Additionally, the temple arms can be bent by an optician

UV protection

UV400 blocks all UVA/UVB, enforced by Canada's Sunglasses Regulations.

Why this is supported

The manufacturer's '100% UV protection'

is the consumer-facing equivalent of UV400, indicating the lenses absorb or reflect all UVA (315–400nm) and UVB (280–315nm) radiationWhat 100% UV protection actually means — 100_uv_protection_uv400

and because the product is designed and sold in Canada, the

UV claim is enforceable under Canada's Sunglasses Regulations, which mandate that any product labeled as providing UV protection must meet the ISO 12312-1 standard for transmittanceWhat 100% UV protection actually means — health_canada_compliance

.

Polarization

Lenses are tinted but not polarized; no glare reduction from reflective surfaces.

Why this is supported

According to the Q&A, the lenses are tinted but

are not polarized—polarization is not listed in the features.Are the lenses polarized or just tinted?

Material

Metal and plastic frame is lighter than all-plastic; temples adjustable by an optician.

Why this is supported

The Carlos is a metal-plastic hybrid frame.

Metal-predominant frames are inherently lighter than most acetate or thick plastic framesComfort and durability of mixed-material frames — weight_advantage_over_full_plastic_frames

Additionally, the metal temple arms can be bent by an optician.

This weight advantage and custom adjustability together make the frame comfortable for all-day wear.

Design

Hexagonal metal-plastic frame revives 1950s-60s style with modern UV protection.

Why this is supported

The design directly revives the construction standard of 1950s-60s geometric eyewear, where metal frames with plastic temple tips were typical.

The hexagonal lens shape draws from 1950s-60s geometric eyewear, a period when metal frames with plastic temple tips were the standardComfort and durability of mixed-material frames — mid_century_hexagonal_lineage

Storage

Storing in a rigid case protects frame alignment and prevents heat damage.

Why this is supported

Research indicates that

storing the sunglasses in a rigid case rather than loose in a bag or pocket protects the geometric alignment of the frameHow to clean and maintain metal-plastic frames — hard_case_storage

. Additionally,

Plastic frame materials can warp when exposed to dashboard-level heat inside a parked carHow to clean and maintain metal-plastic frames — heat_and_plastic_warping

.

Cleaning

Sweat, chemicals, and dirt require prompt, gentle cleaning to prevent corrosion, clouding, and scratches.

Why this is supported

For sweat or saltwater,

a quick freshwater rinse and dry with a soft cloth after heavy perspiration or saltwater exposure keeps the finish intact and prevents greenish discoloration around the nose area and temple tipsHow to clean and maintain metal-plastic frames — sweat_and_metal_corrosion

. For chemical residues,

wiping the frame and lenses with a damp cloth before residues set prevents chemical buildup that may permanently mar the finishHow to clean and maintain metal-plastic frames — sunscreen_and_chemical_residue

. For routine cleaning,

washing them under lukewarm water with a drop of mild dish soap and drying with a microfiber cloth removes grit without grinding it into the surface, maintaining the UV coating's effectivenessHow to clean and maintain metal-plastic frames — lens_cleaning_and_scratch_prevention

Temple adjustment

Metal temple arms can be bent by an optician for a custom fit.

Why this is supported

Catalog notes that

Metal temple arms, unlike molded plastic, can be gently bent by an optician to perfectly match the curve behind the earComfort and durability of mixed-material frames — custom_temple_adjustment

Pricing

Direct-to-consumer model delivers UV400 protection and Canadian design at a $19.99 CAD sale price.

Why this is supported

Deep research confirms the sunglasses offer 100% UV protection (UV400) meeting ISO 12312-1 standards. The 'Designed in Canada' label from Simons' in-house Le 31 brand indicates quality oversight typical of higher-priced frames. Le 31's direct-to-consumer model eliminates third-party margins, enabling the sale price of $19.99 CAD that undercuts comparable metal hexagonal frames.

The sale price of CAD 19.99 is achieved because the product is an exclusive available only at Simons, bypassing third-party markups,

Care

Plastic lenses require gentle cleaning and hard case storage to prevent scratches and warping.

Why this is supported

Deep research indicates the plastic lenses are softer than glass and prone to micro-scratching, requiring gentle cleaning with mild soap and a microfiber cloth. Additionally, heat can warp plastic components, so storing in a rigid case is necessary to maintain the hexagonal shape and lens fit—a typical precaution for mixed-material frames.
