POLARIZED CLARITY - Our popular polarized lenses filter out glare, boost contrast and clarity, cut through road glare, and eliminate reflections from car windows. Polarization enables you to see past the water's surface to spot fish with ease. 100% UV AND IMPACT PROTECTION - Safeguard your eyes with Revant lenses, which filter out 100% UVA and UVB rays to protect against eye discomfort and long-term eye damage. All Revant lenses meet the ANSI Z80.3 impact resistance standard for protection and durability. ANTI-SCRATCH COATINGS - Mirrored lenses feature a frontside coating that resists water, allowing it to roll off easily for a clearer view. OPTICALLY CORRECTED - Instead of being bent to shape, our sunglass lenses are formed with precision and tapered to the correct optical curvature to reduce eye strain. Ideal for the road, range, golf, fishing, driving, or any activity that requires precision. PERFECT FIT - Our lenses perfectly fit Under Armour Yard Dual sunglasses. Revant lenses are precision-measured and cut for an exact match using state-of-the-art optical technology. Whether you need to repair your sunglasses or give your favorite frames a colorful upgrade, replacement lenses by Revant Optics offer original manufacturer quality. All of our lenses deliver both superior impact protection and incredibly crisp, clear views. The American National Standards Institute (ANSI) sets the bar for eyewear performance with the Z80.3 standard; we strive to not just pass their tests, but to crush them. Our lenses feature integrated UV protection that keeps your eyes safe from harmful rays. We use the best optical-grade polycarbonate lens material that has 2.5 times the clarity of other lower-grade lens materials. Unlike competitors who bend their lenses to shape, Revant lenses are formed with precision and tapered to the correct optical curvature to reduce eye strain. Every lens shape is tested for fit at our headquarters in Portland, Oregon so we can be sure when you install them, they will lock in tight and secure. Customize your sunglasses for your lifestyle. From dozens of colors to polarized options, Revant lenses come stacked with features to suit your needs, whether on the trail, driving, fishing, or for everyday wear. With the option to easily fix your frames instead of throwing them away, you can keep the sunglasses like-new and reduce waste in the process.
