Choosing the Best Frame Material for Kids Sunglasses: TPEE vs. TR90

When choosing sunglasses for children, safety, durability and comfort come first. Two frame materials come up again and again: TPEE (thermoplastic polyester elastomer) and TR90 (a thermoplastic nylon). Both are excellent for kids, and OLIVIO&CO uses each where it works best. Here is how they compare.

TPEE

TPEE is a thermoplastic elastomer that behaves partly like rubber and partly like plastic. It is used in demanding parts such as automotive components, and in eyewear for its softness and resilience.

  • Soft and flexible: bends and springs back, which suits babies and toddlers.
  • Durable: resists wear and tear from rough handling.
  • Lightweight: comfortable for long wear.
  • Resists chemicals and weather: holds up to sunscreen, salt water and pool water.

TR90

TR90 is a thermoplastic nylon, originally developed in Switzerland, widely used in sports and children's eyewear.

  • Very flexible: twists and bends without breaking.
  • Impact-resistant: handles drops and knocks well.
  • Very light: often lighter than other plastics.
  • Skin-friendly: commonly described as hypoallergenic.

TPEE vs TR90 at a glance

  • Feel: TPEE is softer and more rubbery; TR90 is firmer and holds its shape more precisely.
  • Flexibility and durability: both bend rather than snap, which is what matters most for kids.
  • Weight and comfort: both are light enough for all-day wear.
  • Price: TPEE frames are often a little more affordable; it varies by brand.

Which is right for your child?

  • Babies and toddlers: a soft, very flexible frame is kindest on small faces and survives being chewed, dropped and sat on.
  • Active kids, youth and teens: a firm-but-flexible frame keeps its shape and fit during running, climbing and sport.

What OLIVIO&CO uses

  • Toddler & Baby (0–3 years): soft TPEE frames.
  • Kids, Youth and Teen & Adult sunglasses, sport sunglasses, shield sunglasses and screen glasses: flexible TR90 frames.
  • Lenses: polarized TAC lenses with 100% UV protection on our sunglasses, and impact-resistant polycarbonate lenses on our sport sunglasses.

Whatever the material, also check for 100% UV protection and a frame sized for your child's age.
