I tried my first water drops but it looks as if my focus is not so good, or do I need glasses?

I loaded my wife`s zink with water and focused on a object that I put on the spot where the drop hit the water. I did not use a flash. I had a window close to the zink and a extra lamp next to the zink. These 2 photo`s were the best of about 50 photo`s I took but it still looks a bit out of focus.
Any ideas?
