- Pure titanium and beta-titanium are 50% lighter than standard metals, hypoallergenic and completely corrosion-resistant.
- Cellulose acetate is a plant-based polymer that allows for rich color depth, multi-layered tortoiseshell patterns and heat-molding anatomical custom fit.
- Stainless steel and Monel offer structural strength, slim profiles and spring hinge durability for everyday reliability.
Titanium: The Benchmark in Featherweight Luxury
For individuals who wear glasses 16 hours a day or suffer from nose bridge pressure marks, pure titanium is unmatched.
Titanium possesses an extraordinary strength-to-weight ratio. It does not rust or tarnish from skin acidity and is 100% hypoallergenic (nickel-free), preventing skin irritation and green residue.
Beta-titanium alloys incorporate memory flexibility, allowing temples to bend under stress without snapping.
Cellulose Acetate: Bold Color & Tactile Warmth
Unlike cheap petroleum injection-molded plastic that becomes brittle and fades over time, premium acetate is crafted from renewable cotton and wood pulp fibers.
Acetate sheets are layered, cured and hand-polished, creating glowing translucency, Havana horn textures and deep tortoiseshells.
Opticians can gently warm acetate to sculpt temples around your mastoid bone for a bespoke non-slip fit.
If your prescription is higher than -4.00D, acetate frames have thicker rims that naturally conceal thick lens edges for a sleeker profile.
Material Selection Summary
Choose Titanium: If you prioritize zero-weight comfort, minimal aesthetic or have sensitive/reactive skin.
Choose Acetate: If you love statement silhouettes, rich colors and vintage or modern architectural presence.
Choose Stainless Steel / Combination: If you seek ultra-slim wire aesthetics with high tensile strength.
