Why 1.61 Lenses Resist Cracking Better Than Polycarbonate

Why 1.61 Lenses Resist Cracking Better Than Polycarbonate

When choosing prescription sports glasses, durability is non-negotiable—especially if you're traveling, competing, or training daily. One of the most common concerns we hear is: “Will my lenses crack under pressure?”

That’s why at Blinded Wear, we only use 1.61 high-index lenses for our prescription sports glasses. They don’t just offer ultra-sharp vision—they also resist cracking better than standard polycarbonate lenses. Here’s why.


What Are 1.61 High-Index Lenses?

1.61 lenses are made from a high-index plastic material that bends light more efficiently than regular lenses. This allows for thinner, lighter, and more impact-resistant prescription lenses, even for stronger RXs.

They’re especially ideal for athletes who want sharp vision and lighter frames without sacrificing durability.

1.61 vs. Polycarbonate: Which Is Tougher on the Court?

Polycarbonate lenses are widely marketed as “impact-resistant,” and they do perform decently in low-stress environments. However, they fall short in key areas where athletes need more from their eyewear:

  • Crack resistance: 1.61 lenses are less likely to crack under suitcase pressure, TSA handling, or ball impact.
  • Heat resistance: Polycarbonate can warp or micro-crack in high heat; 1.61 holds shape under sun or travel conditions.
  • Long-term integrity: 1.61 lenses resist stress fractures and lens fatigue over time, especially during rough tournament travel.
  • Optical clarity: Polycarbonate lenses often suffer from chromatic aberration; 1.61 lenses provide sharper edge-to-edge clarity.

Bottom line: If you want lenses that won't crack when packed tightly or left in a hot car before a match, 1.61 is the smarter, sport-tough choice.

Real-World Scenarios Where 1.61 Wins

Our athletes report 1.61 lenses holding up in:

  • Hot dashboards: No warping during summer tournaments
  • Suitcase compression: Survive under pressure when packed for travel
  • TSA mishandling: Maintain clarity and shape even when tossed in bins
  • High-impact rallies: Resist stress from fast ball speeds and court collisions

That’s why our lifetime RX warranty covers lens cracks from travel damage. It rarely needs to be used—but when it does, we’ve got your back.

Final Thoughts

When performance and durability matter, don’t settle for standard polycarbonate. 1.61 lenses are thinner, clearer, and more resistant to the real-world damage athletes face—especially when travel, heat, or impact is part of your routine.

Every Blinded Wear RX pair comes with 1.61 high-index lenses standard and is backed by our unlimited lifetime RX warranty—including coverage for cracks caused by travel.
