When did Zacharias Janssen invent the compound microscope?
Hans Janssen and his son Zacharias Janssen, Dutch spectacle-makers, are frequently cited as having invented the first compound microscope in 1590, but there is a good deal of dispute. They may not have. Zacharias Janssen was the one who actually made the claim, and in the middle of the 1600's. A number of historians, however, agree that it is imporbable that 1590 is correct. There is a good deal of evidence that Zacharias Janssen was born somewhere around 1590. A link is provided to the Wikipedia article on the optical microscope where a brief history of the device can be reviewed.
Who designed the microscope?
The term microscope technically applies to any magnifying arrangement of lenses, one or many. Single lens magnification has been known since about 1000 AD and no inventor is recorded by history. Around 1590, several individuals compete for recognition as the inventor of the compound microscope which is a microscope using two or more lenses. See the link below to the related question, "Who invented the microscope?" About 1670, Anton van Leeuwenhoek dramatically increased the magnifying power of the simple microscope.
Why is it that in a pair of bifocal glasses the converging lens at the bottom and the diverging lens at the top?
It is a split screen usually the bottom part is cut as the (close up) lens the normal or larger part of the lens is normal- depending on whether one needs primarily distance or close-up correction, or for reading. the bottom lens group is usually secondary, not the main task. Franklin invented bifocal eyeglasses. He also devised the lightning rod, Franklin stove and *Long arm, lever device often used in grocery stores.

How was the first compound microscope different from Antony Van Leeuwenhoek microscope?
Compound microscopes have more than one lens. The first (objective) lens magnifies the object to produce an image. Subsequent lenses magnify an image produced by a previous lens.Leeuwenhoek's "microscope" had only one lens -- simple magnification only.
