With the right light can you turn the lens in your eye into a microscope?

So, I was putting water in a 5-gallon glass jug with a rubber stopper lid, and the rubber stopper would not stay in the top of the jug because the air was pushing it out. So what to do? I poked a hole in the rubber stopper with a surgical needle. Worked like a charm. Well, I happened to look at a light close by through the miniscule hole in the stopper. Usually when you look through even the tiniest hole you can get a clear image of the other side. This time the hole was so small that I could just make out the light bulb, but what was very apparent was a very clear image of the floaters in my eye. It was like looking through a microscope. I could see them crystal clear!

Did I turn my eye into a microscope by pumping just the right amount of focused light into it?

Could I put something tiny right near my eye and magnify it by the same means?

What is going on here?
