Hi,
I've been bloviating on this forum about these SSP Top Focal shooting glasses since I bought my first pair. I'm just a customer, not a paid spokesman. But these work so well for me that I just have to share the love and hope it helps someone else. I've bought a couple of sets from the link below.
Wow, that's a big URL. I hope it links properly. Anyway, like it says in the video on that page, the bifocal lens is on the top of the shooting glasses so you don't have to tilt your head back to use the reader lens to see the front sights clearly. The top focal lens lets you see your iron sights clearly from a natural stance. It works great for me and iron sights. It might work for others too.
The first set I bought was top focal on the right side and a clear lens on the left. I don't think they have those on the website any more. It was called the "Premier" kit. I contacted the owner and he still has a few of those kits left. But he says once the "Ultra" kit came out, it became the best seller. The Ultra kit can be configured with top or bottom lenses, either or both. IOW one bifocal on the top and one bifocal on the bottom, or both bifocals on top, etc.
When I got new prescription glasses I asked my opthamologist if I could get a bifocal on top but they were unable to make that kind of lens. Hence the SSP at the range.
I have a couple of optic pistols with the Holosun 507 installed. For some reason that dot looks clear without any corrective lenses. One of those is in my carry rotation. I don't want to ask the bad guy to wait while I put on my special shooting glasses.
OK, I'll shut up now. Thanks for putting up with me.
Thank you for your indulgence,
BassCliff
