Flying Eyes Cassowary Sunglasses | Narrow & Standard

Built for comfortable wear with helmets and headsets, Flying Eyes Cassowary sunglasses combine flexible Resilamide™ frames, millimeter-thin temples and impact-resistant polycarbonate lenses. The wraparound-inspired design is particularly suited to cycling and other helmet-based activities, with thin temples that also help reduce pressure beneath aviation headsets.

Why Choose Cassowary?

• Resilamide™ frames: Flexible, durable construction for active use.
• Millimeter-thin temples: Designed to fit comfortably beneath helmets and headset ear seals.
• UV400 lenses: Polycarbonate lenses with 100% UV blocking, as specified by Flying Eyes.
• Adjustable nose pads: Customize the fit for comfort and stability.
• Lens options: Choose from six available lens tints, including photochromic lenses that adapt to changing light.

Choose Your Cassowary Configuration

Select Narrow or Standard frame size. Both are offered in Matte Black, with six lens choices: Clear, Dark Solid Gray, Gradient Gray, Mirrored Emerald, Yellow and Photochromic. Choose the lens option that best suits your lighting conditions and intended use.

Prescription note: Flying Eyes does not offer Cassowary with prescription lenses due to the lens shape.
