Spy Optic Czar owners, if your lenses are scratched or damaged, these Revant replacement lenses are exactly what you need. Precision-cut to fit your Czar frames perfectly, these lenses lock in securely just like the originals. Made from optical-grade polycarbonate that's 2.5 times clearer than cheaper materials, you get crisp vision without distortion. The 13% VLT neutral tint filters out 87% of visible light, giving you comfortable brightness reduction for everyday wear. Being non-polarized means you can still read LCD screens on your phone or car dashboard without issues. The anti-scratch and water-repellent coatings help maintain clarity and make cleaning easier. Most importantly, they provide 100% UV protection to keep your eyes safe from harmful rays. Revant tests every lens shape at their Portland headquarters to ensure proper fit, so you don't have to worry about loose lenses or gaps. The injection-molded construction with proper optical curvature reduces eye strain compared to cheaper bent lenses. If you love your Spy Czar frames but the lenses are past their prime, this is a much more affordable option than buying entirely new sunglasses. The quality is professional grade, and installation is straightforward with the proper tools.
