Scopolamine (which is the main ingredient medicine in the Transderm Scopatch) may have gotten on your hands when you applied the patch and from there you may have inadvertently gotten the scopolamine into your eyes. This medicine is used by eye doctors to dilate pupils and for therapeutic cycloplegia. Have you noticed that your pupils are larger than average when you look in the mirror? Cycloplegia basically puts your self-focusing system to sleep, thus near-range vision is blurry. The effect lasts for a few hours up to a few days, depending on how much medicine is used. Usually, near focus does come back to normal without any permanent or long-lasting effects. But I certainly understand that the effect is annoying while still ongoing. By any chance did you wear contact lenses on the cruise, which you are still using? If so, the contact lenses may also have some scopolamine on them. If it has been more than 5 days since you took off the patch, you should see your eye doctor just to make certain that nothing else is going on. Best!
