I always thought the Prizm was Panini's answer to Topps Chrome, but since Panini can't seem to come up with anything original anymore it had to follow Topps' formula and come out with a "chrome" version of one of it's regular sets. And that of course is it's Donruss sets.
Like Chrome you get 4 cards per pack. I stopped by my LCS to pick up a few supplies, peruse the dime boxes and drop board and since this was the cheapest football on the shelves picked up a couple packs of Optic. Sorry for the crappy photos my scanner is packed away.
It's nice when you get a card for your team set. This is the Aqua "refractor" parallel #/299.
