Nayah Square Sunglasses

Verified claims

Polarization

PVA/TAC sandwich construction achieves over 99% glare extinction without color cast.

Coatings

Factory-applied anti-scratch and superhydrophobic coatings protect the lens.

Tint

Category 2 tint (18–43% VLT) suits both bright and shaded conditions.

Optical clarity

TAC polarized lenses achieve over 99% glare extinction and zero distortion

Scratch resistance

Anti-scratch coating protects soft TAC lenses from everyday abrasion, preserving clarity.

Water beading

Water beads and rolls off, carrying dust and oil, so lenses stay clear with minimal cleaning.

Coating layering

The superhydrophobic coating is a separate topcoat applied over the anti-scratch layer.

Optics

TAC lenses eliminate optical distortion and block 99% of horizontal glare.

Lens coating

Anti-scratch and superhydrophobic coatings protect lenses from abrasion and repel water, dust, and oils.

Fit

Lightweight TAC lenses (1/3 weight of glass) and heat-adjustable frame provide comfort and stability.

Weight

TAC lenses weigh roughly one-third of glass, reducing clamping force.

Optical quality

TAC lenses eliminate distortion and cut 99% of glare without color cast.

Adjustability

Bio-acetate frame can be heated and reshaped by an optician for a custom fit.

Hypoallergenic

Acetate frame with no metal skin contact is nickel-free and hypoallergenic.

Width variation

Black variant is 138 mm wide; Maroon Brown is 149 mm.

Design heritage

Barcelona-inspired square frames with category 2 tint and superhydrophobic coatings for urban–beach versatility.

Lens quality

TAC lenses weigh 1/3 of glass and provide over 99% glare extinction without distortion.

Why biosourced acetate matters for frames

• Bio-acetate can be gently heated and precisely reshaped, a property it shares with all cellulose acetate — allowing an optician to tweak the temple arms or bridge for a custom, secure fit that eliminates slippage without risking cracks.
• The 45% bio-based content comes from castor plant seed oil used as the plasticizer, not the cellulose itself, so the frame retains the signature high-polish lustre, warmth, and ability to be custom-fitted by heating — advantages that pure injection-molded petroleum frames can't match.
• Since the frame body is entirely acetate — no metal touches the skin — the Nayah is inherently nickel-free and hypoallergenic, making it a safe choice for anyone with metal sensitivities or contact dermatitis, even in hot, sweaty conditions.

TAC polarized lens technology and everyday use

• TAC lenses weigh roughly one-third of comparable mineral glass, so the Nayah’s full-frame square silhouette stays planted on the nose without clamping force — a benefit you'll notice after hours of touring or beach reading.
• The superhydrophobic topcoat creates a microscopic texture that forces water into tight beads that roll off with minimal tilt, carrying away dust, oils, and salt spray — after a beach walk or a light drizzle, a quick head shake or single wipe with the included cloth restores clarity.
• Because bare TAC is relatively soft and easily marred, the factory-applied anti-scratch coating is essential to preserving long-term optical quality; it creates a hardened surface that withstands everyday abrasion from wiping, pocket-stashing, and occasional drops onto pavement.
• The Black variant's category 2 tint sits in the sweet spot for changing light — dark enough to cut glare on bright afternoons yet translucent enough that you can keep them on when stepping into a café or walking through forest shade, avoiding the disorienting 'tunnel vision' of darker category 3 lenses.
• A polyvinyl alcohol (PVA) polarizing film is laminated between two TAC layers, a method that routinely achieves over 99% glare extinction; horizontal reflective glare from water, asphalt, and car hoods is virtually eliminated without the faint color cast that cheaper, extruded-polarized polyester lenses sometimes impart.
• TAC is the dominant polarized-lens material because its manufacturing process — casting into optically perfect sheets rather than injection molding — eliminates the internal stress birefringence that can introduce distortion, giving the Nayah a uniformly sharp, color-accurate view across the entire lens.
