plastic lenses
Plastic (or CR-39, if you want to get technical) is about as close to glass clarity as you can get without the weight or the price tag. It's our most affordable option and it’s very easy to tint. A few honest notes: plastic lenses run a little thicker and heavier than polycarbonate, and they're easier to scratch, crack or shatter. They also don't play well with drill-mounted or semi-rimless frames, and they're not an option for anyone under 18.
most common
polycarbonate lenses
Polycarbonate (or "poly," to its friends) is the workhorse of the lens world. It's thinner, lighter, and a whole lot more impact-resistant than plastic. And unlike plastic, it works with drill-mounted and semi-rimless frames. All those upgrades come with a slightly higher price tag. If you’re leaning towards poly lenses, keep in mind that it has a touch less clarity than its glass and plastic cousins, it scratches more easily than you'd expect (we add anti-scratch coating to every pair, but still), and it doesn't take tint as nicely as plastic.
best for strong prescription
High-Index Lenses
Contrary to popular belief, a strong prescription doesn’t doom you to thick lenses. High-index are the thinnest lenses we make. They're lighter and thinner than plastic (though a bit heavier than poly), and they can be used for drill-mounted or semi-rimless frames. Making lenses this thin takes serious work, so high-index is usually our priciest option. Every pair comes with anti-scratch and anti-reflective coating, since high-index lenses can be reflective on their own.
highest clarity
glass lenses
If clarity is what you're after, nothing beats glass. Glass delivers the sharpest optical quality of any lens we offer. And it's naturally scratch-resistant, no coating required. But keep in mind: glass is heavy, so if you're not used to it, there's an adjustment period. It's also not impact-resistant, which means a hard drop can chip or shatter it. But for the right wearer, no other lens comes close.
