I had need...
I had need for glasses with corrected vision at around 5 feet. I'm near sighted with relatively poor vision and quite a bit of astigmatism. I went to question an eye doctor at Costco and luckily she had experience making glasses for shooters. We set up a picture from a magazine at 5 feet and she found the right prescription for me at that distance. I went with the biggest lens I could (to let the most light in) because sometimes I used them in less than optical light conditions and the large lens proved fantastic for that. The best I can describe the change at the distance they were designed for is it is like the last bit of fine adjustment on a microscope or binoculars that brings everything into sharp focus. I estimate they improved my vision in the area of 15%, which is quite a bit in use. Add in the low light improvement and the difference is remarkable.
I don't feel anti-reflective coatings are any good and, in my experience, they seem to create more glare. As for playing pool, my regular glasses are better than the special ones because I lose vision at the far end of the table. I believe if I had a pair made with corrected vision at 9 feet they would be perfect for pool.
