Frequently Asked Questions
Q: Will the lenses help with eye strain during long drives?
A: Yes. The combination of Polarisation+ (which cuts road glare) and Blue Light Blocking Technology (which reduces high-energy visible light) significantly minimises eye fatigue, keeping your vision relaxed and focused during long journeys.
Q: How durable are the frames if I drop them?
A: The Fistral is made from TR90 Memory Polymer, which is far more resilient than standard acetate or plastic. It is designed to flex rather than snap under impact, making it highly durable for travel and outdoor use.
