This has to be the finest crafted magnifier that attaches to a hat. All Stainless steal, changable lens, and the best part it is not in a fixed position. The Hat Eyes can be moved closer or further from your eyes to get a better focus, it can also be angled you you are always looking through the len straight on. Easily clips onto the brim of a hat and easily removed with out making holes in the hat. We all love Flip Focals, but this blows them away.
