 Yeah, so porcos John actually is solving a problem that I've thought about the same thing And he says one of the things on the design side that I lament on with the Apple Vision Pro is The same as VR headsets as well And that is there's nothing that covers or protects the internal lenses including your snap in prescription or you know Lenses and stuff like that. So the lenses are open. They give you that nice cover for the front They do not give you any kind of cover for like the inside and I don't know if they think just because it's kind of naturally Protected by the face shield thing, but you know dust and dirt and things can get in there And so he said I reverted to something that I used on my digital cameras for years a lens pen And if you don't know what a lens pen is it's like Looks like a fat like marker and you pop the end off and it has a little Articulating well, there's a couple different ways that this one you're showing Dave showing on the video has a slide out Where you push it out in a little, you know like a mechanical pencil You might slide it out. Yep. Yeah comes out the end of it I have one where you pop it off and it has a little pad with an articulating kind of thing And you would use it for your digital camera to get in and like clean off the lenses or the sensors or stuff like It's you know, it's a lens cleaning cloth But it the end pen form and he says you can spend 10 bucks on a lens pen or 25 on a full cleaning kit But they have a non-scratch carbon head that makes your glass super clear again You don't ever clean the Apple you don't ever clean the Apple visual vision pro internals with a rag or a towel They can scratch and they also tend to leave debris and fibers So yeah, these little lens pens are great and again camera enthusiasts have used them for years and know about them I have one because I have a telescope and it came with a kit with you know Telescope that I bought for and you know the the problem I always thought was like even if you try to use a cloth, which you know as he says you probably shouldn't do Getting down in there, you know, it's it's kind of a reach I guess you could pop off the the face shield. I never thought about that Think comes off pretty easy. It's not really attached so you can get on them more easily that way But yeah, lens pens are great
