I am having trouble seeing both my iron sights on my pistols, and my paper targets at 45'. I do not wear prescription glasses, and with reading glasses I can see the iron sights, but the target is blurry. Tried it both ways, and my groups are about 10" I am experimenting with peep hole glasses. Through a small peep hole, the depth of field is such, both close by and far objects are in focus. With some home made glasses, I can tighten my groups a little. Anyone know of peep hole marksmanship glasses for sale in the USA? Found some in Canada. Any help or wisdom would be appreciated.
