Used to do this to my shooting glasses, just put Scotch tape on my non-dominant eye so I could leave it open while shooting open sights.

I’m “wrong eyed” so my brain always tried to look down my gun with my left eye. The tape solved it. With practice I can now shoot well with regular glasses, though it’s still more comfortable to use taped glasses.

Don’t listen to the wrong prescription talk as it will hurt your eyes. Tape is cheap and safe.

You could buy cheap plastic ones and scuff them up with high grit sandpaper, diffusing the Lenses.

Do you… do you have eyelids?

You should have eyelids.

Seriously though, blurred glasses seems like a recipe for a nasty headache. You would probably be better off with nothing, like eye covers for sleeping.

You really don’t care about your eyesight do you… this will absolutely wreck your eyes.
