I've just bought a little Springer for using with open sights. Anyway I've not really used opens for 40 years when my eyes were young, so I went to the range yesterday with my "new to me" toy and my variofocal glasses (which are fine for 10 metre pistol shooting).
I was shooting at 20-25 yards aiming at 1" targets and I found it really difficult with my glasses on and had to push them hard into my face, I also had to alter my position so I could look down the sight line.
When I returned home I tried some reading glasses but couldn't make out the target.
The only solution I can think of is to buy some "Dennis Taylor" type snooker glasses.
Does anyone have any other suggestions?
