Yeah. A couple of things. You know, the price point on MiSight is lower outside of the U.S. So, when we talk about the U.S., right, FDA approval and running about 750, you know, you're getting outside of the U.S. Let me call the global range, more 500 to 750, and we're seeing a lot of the optometrists out there sell this as like a package offering. So that wouldn't surprise me, you know, moving forward that they kind of do that as, hey, regardless of what product you're getting, and how we're going to sell it, we're going to sell these together. So, maybe you get, you know, to your contact lenses, or it's two or three glasses, right? Because kids are going to lose their glasses or break them or need to update their script, that kind of stuff, right. So, I think that at the end of the day, my gut is that the pricing is probably in a pretty good place right now. Where I've seen the pricing on glasses lower as you're talking about, that's also for one pair of glasses, right. So, you end up saying, okay, well, you either kind of give them two glasses or three glasses, how you're going to look at that. It seems to be coming together at a pretty decent price point around where we're sitting at right now. So, then I think the next thing goes to saying two components of it, right is, yeah, they're both efficacious and they're being proven to be relatively similar at the end of the day in their success rates. So, then you go tom okay, is the kid going to really wear those glasses, right. Because they have to wear them all the time, right. 10 hours a day, every day. And that's where we're seeing optometrists push towards it and say, hey, they're both as efficacious, but one of them I'm guaranteeing the child's wearing contact lenses. The other one I'm not. That's why we're seeing more of the push from a lot of optometrists for kids who are 10 or older, moving them into contact lenses.
