That's an astute observation, and as others mentioned, cooking spray, WD40, vaseline, etc, works well on the bike but isn't used often on goggle lenses. I actually looked into this as a business venture a little while ago. As you might know, tear offs are banned in most Australian areas due to farmers complaints about their livestock ingesting the used tear offs.
In the US, they obviously haven't banned them, but they may eventually.
I personally thought that having decomposable tear-offs would be an interesting concept. A company back in 2011 gave it a try, and made their OT's from a sugar composite, but they weren't completely transparent, and after 3-4 TO's stacked up, they became really hazy and limited the rider's vision. They went out of business around 2012 as best as I could tell. I have no education pertaining to materials science or engineering, so then I thought about sourcing an existing technology from another company, and licensing it as a motocross goggle application. There's a company founded by some MIT (Massachusetts institute of technology) students called LiquiGlide. They started out by making a clear film that goes on the inside of ketchup bottles, and have a huge licensing contract with Heinz. Basically, nothing sticks to it at all, and I thought that they might be open to a conversation about expanding beyond food containers, and into other markets. Despite multiple attempts to contact them, and applying for several jobs there, they have never responded to my outreach. I genuinely think that this would be a groundbreaking improvement to the sport, and rider safety, but don't seem to have enough clout for them to take notice.
Here's a link to their YouTube video -
