Sure. Yes. When you look at China, it's a little different market than a lot of people probably think, when they think of optometry. Here in the U.S. and Europe, you get a lot of markets where there's independent optometrists or its heavily driven by change. You certainly get that in China, when it comes to what we'll call regular contact lenses. When you're talking about a product, like MiSight treatment products, they're largely sold through hospitals. So that's what we're going to see from MiSight, it is sold through some major, major hospital there, whether it's a public owned hospital, government owned hospital, if you will, or a private hospital. So it's a different call point largely than what you would have for your traditional contact lens business. You are correct, SLR has a very strong distribution network there, we received the approval on MiSight a little bit faster than we were anticipating it. So I would just say we're in -- let me put it this way, with active negotiations right now you should hear something shortly on how we'll distribute that product through that marketplace. But just to step back a little bit on that, as I mentioned on the call, right, we received the approval, the approval does require us to manufacture and package those products, everything post approval. So we're very actively doing that right now ramping everything up, we'll get that product into the market probably kind of in the November, December timeframe is when you'll see it really coming in. We're supporting that with kind of pre-launch activity right now. And then, we'll have that in the market much more aggressively, kind of in the January, February timeframe. If we look at the 2022 targets, we talked about those a decent amount in the past. I'm more comfortable with the discussions we've had. We talked about that kind of $50 million number for MiSight next year, we talked about $100 million myopia management number. We will firm that up in December when we give the guidance. The only negative that I've seen on that, frankly, has been currency, a lot of our sales [indiscernible] MiSight or international sales, but outside of that, no, I'd be more optimistic on our 2022 myopia management growth opportunities.
