20/300 in my left eye; 20/400 in my right. Could not shave without my glasses on. However, trying to shave with bifocals really s****d. Had to dig out an old pair of single vision glasses from 21 years ago.

Lenses (eye pieces) get in the way when I do my cheeks (toward my nose) but I manage with it.
Namaste,
