Need help.
One day, out of nowhere, this bubble appeared on the screen. There was no pressure or sudden temperature changes or anything like that.
I waited for the new lenses to arrive, thinking that after I removed the older ones, it would be just a matter of adding a little pressure to solve it.
But it wasn't. I can feel it like a bubble, very very slightly raised, but I have no idea on how to fix it.
