アセテート×チタンサングラス

This material pairing allows the acetate and titanium sections to contribute different visual qualities to the design. Acetate can define the front through color and thickness, while titanium components can create finer structural lines.

• Square frames make the acetate outline feel more architectural.
• Round designs soften the material contrast through curved edges.
• Browline frames concentrate attention across the upper frame.
• Geometric shapes make the contrast between angles and materials more visible.
• Transparent acetate reveals more of the underlying structure.
• Tortoise and multitone finishes introduce surface variation.

Focus first on the acetate front, as its shape and thickness usually create the strongest visual impression. Then consider whether the titanium details reinforce or soften that outline.

Round Faces
Square or geometric frames can introduce angles and clearer edges.

Square Faces
Round shapes or frames with softened corners can provide contrast to a strong jawline.

Oval Faces
Square, round, browline and geometric silhouettes can all work. Choose according to the amount of structure you prefer.

Long Faces
A wider front or deeper lens shape can create better visual balance than a narrow, shallow frame.

Heart-Shaped Faces
Round or softly shaped frames can reduce emphasis across the upper face. Browline designs create a stronger top line when a more defined look is preferred.

Diamond Faces
Rounded edges can soften prominent cheekbones, while a geometric frame creates a more deliberate angular contrast.

In acetate and titanium sunglasses, color controls the visual weight of the front while the finer metal elements affect the frame’s overall balance.

• Black acetate creates the strongest and most defined front.
• Tortoise introduces warmth and breaks up broad surfaces.
• Transparent acetate makes the frame feel more open.
• Grey and brown provide a quieter alternative to solid black.
• Blue, green and orange introduce a more expressive accent.
• Dark titanium details blend into the design.
• Contrasting titanium details make the mixed construction more visible.
• A wider or thicker front increases the impact of the acetate.
• A slimmer front creates a more restrained transition between materials.
