I think I'm going to talk to my eye doctor about getting a pair of glasses just for shooting/filming. Close range correction on the right (for me a right handed/right eye dominant shooter), and plain glass on the left. It would allow me to screw the ocular of the scope all the way in as Ted says, but I'd still be able to see long range in the left eye, as the cataract lens in my left eye is for long vision.
