Yes. Well, I think some of it, you're looking at the earnings release that we put out there, right. And so you're talking about single use spheres there. If you look at single use torics, especially torics, which are strong for us, multifocals, you're seeing better performance there. So if you narrow into that, that line item, you're talking about weakness in single use spheres coming from older hydrogel lenses, right? The whole industry, that's still a massive part of this industry, it's 2.4 billion in sales, and it's declining, and it's being replaced by silicones. And that's where we're doing well, when you look at what happened at the end of the quarter in terms of people not ordering, when you see orders get delayed. What we've seen here through this pandemic is, the orders that are getting delayed and the pull down in channel inventory is tied a little bit more to daily silicones than it is anything. So at the end of the day, the weakness is coming from weakness in the industry in the marketplaces, daily, traditional dailies move away, and daily silicones transition over. When it comes to the sphere, we had a strong sphere quarter with MyDay. I think that one of the things that makes us feel good about that and looking specifically at the daily sphere side of things, is the success we're having with MyDay sphere coming back in the marketplace. We were constrained. I talked about that for a while on past earnings calls, we pulled that product off of market in several countries, right? We didn't launch it as aggressively as we could. We are now unconstrained on that product. So you're seeing MyDay out there, unconstrained we're aggressively rolling it out. I feel really positive about the future of that. And I don't want to downplay clarity, either, by the way because clarity, definitely doing well. But MyDay is definitely outperforming.
