I had to get reading glasses and I have to have them to see the reticile clearly.
As I was looking at my different scopes with them on, everything was fine until I looked thru my old Weaver dual crosshair k4. It was blurry i took of my glasses and it was clear! All my other scopes are late model and i had to have my glasses on for all of them. what gives did the old boy i got the scope from have it made for him back on the day? Thanks Mike

Mike, have you adjusted the focus of your other scopes without your glasses on? Most scopes have adjustable oculars for this reason. What I think you found was a scope that was adjusted to your perscription by someone else.

Great question mike61. I wonder the same thing myself from time to time. I am a free lance explorer and try to take change in stride. I happily got rid of all my old scopes.
