So like most folks several years ago when I hit 45 my eyes changed and I couldn't see up close very well anymore and had to start wearing reading glasses.
Normally I wear contacts to correct nearsightedness. My shooting eye is 1.75 and my left eye is 3 point something. When my eyes changed, I couldn't see my sights very clearly anymore - they were blurry. I'm sure all of you old timers know what I'm talking about.
For some years I punched a little disk out of some electrical tape, and then punched a 1/8" hole out of the center of that, and stuck it to my shooting glasses to make an aperture. Cheap, and worked fairly well, at the expense of field of view.
Now I've worn reading glasses for years, also, and of course I tried shooting with them and found that while they made the sights clear they made the target blurry. I was wearing "1.25 magnification" readers.
Well, I have discovered that that number is not magnification. It is "diopter". I had never considered 1.0 "magnification" readers as I did not think they would have any correction. But in fact, a 1.0 diopter does make a difference. And for me, it's darn-near perfect. When I'm wearing 1.0 readers, my sights are crystal clear and there is not much impact on distance vision.
