Spy Bias Lens
Here's what other sites are saying:
Of course your sister destroyed your Spy Bias lens, so quickly fix it up with the Bias Goggle Replacement Lens and get back to the distortion-free and optically correct vision you're used to thanks to ARC spherical dual-lens technology. It's almost surprising that your sis did what she did to your lens because it has anti-scratch protection that let you brush past tree branches for years. At least there's nothing she can do about the anti-fog technology that contains Spy's super secret formula to keep your vision as clear as the bluebird days you love to ski in.
