Category 1: Metal Frames – The Titanium Family

Light, strong, and hypoallergenic, these are ideal for sensitive skin or long wear.

1. Titanium

• In a nutshell: The classic choice – strong, light, and understated.
• Key features:
  • Very light: About 50% lighter than standard metals, so it feels almost weightless.
  • Hypoallergenic: Naturally resists skin irritation and won’t tarnish.
  • Sturdy: Holds its shape well, but if badly bent, it may not spring back fully.
• Best for: Anyone with metal sensitivities, or those wanting durable, lightweight frames for daily wear.

2. Beta Titanium

• In a nutshell: More flexible than pure titanium – easier to adjust for a custom fit.
• Key features:
  • Flexible: Can be shaped more easily to fit the curve of your head.
  • Adjustable: Combines lightness with easier fitting for different face shapes.
  • Springy: Tends to return to shape after minor bends.
• Best for: People who need a precise, comfortable fit, especially with unique face shapes.

3. Memory Metal (Nickel-Titanium Alloy)

• In a nutshell: Super flexible – bends and springs right back.
• Key features:
  • Highly elastic: Can handle a lot of bending without damage.
  • Durable: Very resistant to everyday knocks and pressure.
• Best for: Active kids, teens, or anyone who needs tough, resilient frames.
