Sunglasses are performance gear. ZEISS PerformaSun is engineered to perform.

Look at how you've outfitted yourself for the things you do outside. The right bike. The right rod. The right shoes. The right club for the right yardage. Now look at your sunglasses. Did you purchase them off the rack? Are they the same pair whether you're driving, fishing, or watching your kid's game. Your sunglasses are performance gear. They're the lens through which everything else happens. And for most of us, they're the one piece we still treat like an accessory. ZEISS PerformaSun® is built for people who want their eyes to perform like the rest of their gear: nine prescription lenses, each engineered for a specific outdoor environment. Here's what to know before you pick one.

If you wear glasses or contacts, here's the picture most of us fit into:

About 91% of Americans who need vision correction wear prescription eyeglasses. Only around 33% own prescription sunglasses. And roughly a quarter of adult prescription wearers reach for non-prescription sunglasses outdoors, trading their correction for sun protection, or going without correction entirely.¹

That's a big gap, and for most people it isn't a deliberate choice. It's a default, because sunglasses have always been sold as a fashion or sun protection accessory, not as performance equipment.

You wouldn't ride on the wrong bike or play a round with the wrong clubs. The same logic applies to your sunglasses. They're either engineered for what you're doing, or they're getting in the way of it.

A performance sunglass lens has to do three things at once: block UV, cut glare, and let your eyes see the contrast and color the scene demands. The first job is straightforward. Every ZEISS sunglass lens provides full UV protection up to 400 nm.²

The second and third jobs are where most off-the-rack sunglasses fall short. Standard polarized lenses do one thing very well: they cut horizontally reflected glare. That's a real benefit, and any polarized lens beats no polarized lens. But standard polarization treats every outdoor environment the same. A lake at noon, a road at dusk, and a tennis court in bright sunlight all get the same filter.

ZEISS PerformaSun is built to close that gap. The lens starts with up to 99% polarization efficiency, equal to or better than the premium polarized sunglasses you might already own, and adds environment-specific spectral balancing. The lens isn't just darker. It's tuned for the colors and light conditions of where you'll be wearing it.

The question that points you to the right lens is simple: where do you spend most of your outdoor time?

A few more things to think through, and to bring to your eye care professional:

• Pick for your dominant environment. If you fish every weekend and only ski once a year, optimize for fishing. If you're on the road five days a week and on a boat twice a summer, optimize for the road.
• Get the prescription. This is the gap most people leave on the table. If you need correction to see well, you need correction to see well outside. Squinting through bright light, wearing contacts in dry or windy conditions, or stacking non-prescription sunglasses over your glasses are compromises that cost you both comfort and performance.
• Polarized for most, LightPro Court for court sports. For nearly every outdoor activity, full polarization is what you want. The exception is fast-paced ball sports, where LightPro Court's tuned approach might be the better tool.
• Frame matters. Sport sunglasses are often built into wrapped frames for full coverage and impact resistance. Wrapped frames require a lens design that compensates for the curve, which your eye care professional can address when ordering.

The activities you take seriously deserve the same kind of equipment investment you've already made everywhere else. Better gear gives you an edge: seeing the break, spotting the fish, reading the road, tracking the ball. These are real performance gains in the things you're already serious about.

ZEISS PerformaSun is one option in the broader ZEISS prescription sunglass portfolio, which also includes everyday tinted lenses, polarized options, and self-tinting lenses like ZEISS PhotoFusion® X. Your eye care professional can help you decide which lens fits your prescription, your activities, and your frame.

The best way to figure out which ZEISS PerformaSun lens is best for you is to talk to an eye care professional who can match the lens to your prescription, your frame, and how you actually spend your time outdoors.
