Unbreakable Frames: Materials, Bend Tests & Buying Tips

Quick answer: “Unbreakable” frames typically use TR90/nylon shell materials or resilient metals with spring hinges. They resist everyday drops, flexing and twisting better than standard acetate. For kids, sports or rough use, prioritize impact resistance, lightweight comfort and safe hinges.

Note: Unbreakable lenses are available with frameless specs, which can make almost any rimless frame feel near‑unbreakable in everyday use.

Material & hinge choices

• TR90: Ultralight, flexible, skin-friendly. Great for long wear and active use.
• Acetate: Stylish, shapeable; pick thicker builds if you want more durability.
• Spring hinges: Add flex and reduce temple stress; look for smooth action.
• Fit & bridge: Secure bridge fit reduces slips; silicone sleeves help for sports.

Editor’s picks

Choose frames that can bend without permanent deformation, and check warranty details.

FAQs

Are TR90 frames truly unbreakable? No frame is indestructible, but TR90 flexes and resists cracking better than many plastics.

Do spring hinges break? Any hinge can fail, but spring hinges reduce stress from daily on/off and minor impacts.
