Frequently Asked Questions

TR90 is the unequivocally safest choice for children with sensitive skin or allergy concerns. As a non-metallic, hypoallergenic engineering plastic, it:

  • Contains zero nickel or metal allergens
  • Meets stringent EU REACH safety standards when properly certified
  • Maintains integrity even when fractured (no sharp edges)

Our opticians recommend TR90 for 90% of children under 10 due to its unparalleled safety profile.

For style-conscious teens with moderate activity levels, titanium offers sophisticated durability. For athletes or rough users, TR90 often outperforms despite its lower price.

Memory metal (nickel-titanium alloy) serves niche cases when:

  1. Extreme flexibility is required (e.g., sports goggles worn under helmets)
  2. The wearer has confirmed nickel tolerance via patch testing
  3. Professional fitting is available (improper adjustment may cause rebound)
Note: 15% of European children show nickel sensitivity - always test before prolonged wear.
