It’s acetone based and will eat through most plastics.
Best bet is to try and just pick it off. Other than that, I would simply wait, cyanoacrilate becomes very brittle over time and you should be able to just pick it off in a couple of days.
It may leave a small divot in the lens. But DON’T use nail polish remover.
