I learned my lesson, thankfully at my company’s expense, with progressives a long while back. I’m a bifocal guy now. Small lenses make the issue worse with both kinds.
I have a bunch of single-vision safety glasses in as close to my needed distance correction as possible. Those make irons usable for the most part, and sharpen red dots appreciatively. My correction is only +1.35, so I buy +1.5s. Perhaps someone with worse vision might not be helped as much. They offer good protection as well.
When I got semi-serious about clays, I ponied up for single-vision Decots. Worth every penny. I do have to be careful to take them off when I’m done so as not to be mistaken for an Elton John impersonator…….
