After I had cataract surgery, I can see my sights well enough, not perfectly clear but OK. I like wearing shooting glasses with my flintlock and now need readers so I ordered a pair Vitenzi with readers off Amazon. The readers are OK but the overall lens are not clear glass and distorts my vision enough for the target not to be as clear as it is without my glasses.
This was my second pair, the first was just fine. I was shooting alongside a family at the range; they burned up at least a thousand rounds in an hour or so with nonstop mag dumps out of anything and everything. I even let them shoot my flintlock.
I had a ton of stuff to put the truck in the parking lot, I left my new shooting glasses on the shooting bench as I made repeated trips to the truck. The family left while I was at my truck. When I went back for my glasses and the last load, I found that someone in the family had stolen my shooting glasses on their way out. They projected the image of a bunch of lowlifes but I gave them the benefit of the doubt, my mistake.
