Leupold Vari-X 2.5-8 adjustments

So it’s adjusted enough to use. I think I’m going to send it back to Leupold as I’m having trouble getting crisp images. My vision is 20/30 now, so not like 20 years ago when I was 20/15…but the adjustment isn’t working well. Also seeing a double vertical line..very close together.

Thank you for the input.
CL - I didn’t forget what I said.

I often see that ever since I had Lasix surgery.
