What tricks or gadgets can be used to help 'old eyes' see iron sights for fine sighting work from a bench? I heard about some sort of thing you put on your glasses that forces you to look through a pin prick that helps you focus. What is it and does it work? Any other options?

Thanks in advance

Mickey, I think your talking about the Merit Iris, that attaches to your lens, they are also offering an aputure now for most of lymans peep sights

Dave's right. I use the Merit device for all precision handgun shooting. Don't need it (yet ) for rifles/shotguns.

Here's a link to the website:

That's it. Have you guys ever used them on rifles? The ones for the glasses I mean.

Do they make you a contrare?

I've posted this before, but the cheap, quick, and dirty way is to take a piece of electrical tape and put a small hole in it and stick it to your shooting glasses.

Instant aperture.
