Oakley Bisphaera

The Oakley Bisphaera is designed for athletes seeking high performance.
This sunglass has a dual-lens design and is ideal for a wide range of sports and everyday use. The Bisphaera is built on the insights of the popular Flak 2.0 XL and offers optimized visibility and comfort. The Bisphaera has a slightly deeper lens than the Oakley Flak 2.0 XL.
The Bisphaera features Oakley's patented Prizm™ Lens Technology, which enhances color and contrast to help you see details better.
A major advantage of these glasses is that they can be made to prescription lenses.
