How to see your own iris in your eye 👁️

Have you ever seen your own eyes 👀 very closely, and at a big magnifying. I developed this tool 35 years ago, but I think it can be very helpful for other people, and specifically when one gets a small fragment in one of your eyes 👀 It’s very simple made of a plano convex, or a plan convex lens and a small mirror, the mirror has to sit in a small distance from the back of the lens, so the magnification is as big as possible but still clear enough. I have no idea what focal length the lens has, or how strong it is, back then I just experimented with different lenses.
