Frame material affects weight, visual presence, adjustability and feel. Yet a label such as “titanium” or “acetate” cannot predict fit on its own: thickness, bridge, hinges, volume distribution and workmanship are just as important.

This guide compares materials found across the Frank Lo selection. The specifications and fit of the individual model always remain decisive.

Titanium: slender profiles and precise constructions

Titanium is often chosen for lightweight frames, corrosion resistance and finely engineered details. It can support slim fronts, articulated bridges and flexible temples without visually weighing down the design.

Not every titanium frame has the same weight or flexibility. Alloy, thickness, construction and combinations with acetate or other metals all change the result.

Acetate: colour, volume and surface treatment

Acetate offers broad chromatic and graphic freedom. It may be transparent, layered, matte, polished or deeply textured, and it allows thickness to become part of the designer's language.

Comfort and durability also depend on the sheet, polishing, hinges and professional adjustment. A thick frame is not necessarily heavy, just as a slim front does not guarantee a better fit.

Natural horn: individual pattern and considered care

Natural horn has variations in colour and grain that make every frame different. It is appreciated for its warm touch and non-uniform appearance, but it requires specific care.

Origin, treatment and construction should be checked on the individual product. Follow the maker's instructions and avoid unsuitable home treatments.

Steel, aluminium and composite materials

Stainless steel can deliver thin profiles and stability; aluminium is used in selected projects for low weight and distinctive surfaces. Fibres, polyamides and other composites expand the possibilities for form, flexibility and colour.

Here, too, the material name tells only part of the story. Joints, lenses, nose pads and temples define how the finished frame behaves.

Mixed materials

Many designers combine titanium and acetate, different metals or technical materials so that every component serves a purpose. A front may provide graphic presence while the bridge and temples remain light, or a metal detail may become structural and decorative at the same time.

How to choose

• Begin with fit: width, bridge and temples must suit the wearer.
• Consider use: everyday eyewear and a statement frame may involve different priorities.
• Read the product page: materials and manufacturing country vary by model.
• Ask for advice: known allergies, complex prescriptions or special adjustment needs should be discussed with a professional.

Frequently asked questions

Is titanium always the lightest option?

Not necessarily. Weight depends on the whole construction, not only on the material name.

Can acetate frames be adjusted?

Many can be adjusted by a professional, but the possibilities and limits depend on the model.

Does natural horn require additional care?

It usually comes with specific care guidance. Follow the instructions supplied by the maker and retailer.

A material becomes meaningful when it supports the design, proportions and wearer. Frank Lo can help compare alternatives in Rome and online.
