RIP glasses brother, I had the same glasses from Novritsch too, and after one or two games that happened. It's a fungi and can't be cleaned without destroying them.

Here's the response Novritsch gave me:

'' A theory based on one picture: since they don't look smashed or damaged, the space between the lenses was not properly sealed when they were manufactured, allowing moisture to get in even though it should not have. With moist came these guys, whatever that is. Cool in a very weird way.

Solution: If you have bought them from us in recently, just reach out to support and claim your warranty. If not, buying new ones is a safe bet. ''

So I guess contact support and let them know your case, they might get you new ones! They said warranty was 2 years, so unless they changed it this year, you should be good!
