Two dutch men created eye glasses with multiple lenses placed in a tube in 1590. The eye glasses made objects enlarged, creating the forerunner of the compound microscope and telescope. This helped us see objects appear very large then how we look at it with the naked eye.
- Electron Microscope
An electron microscope depends on electrons rather then light to view an object. Electron microscopes make it possible to view objects as small as the diameter of an atom. The electron microscope was invented in 1931....

Joseph Jackson Lister reduces the "chromatic effect" by showing that several weak lenses used together at certain distances gave good magnification without making the image blurry. This helped people see things withou them being blurry. This was...
