It gave them a direct view into the unseen world of the extremely tiny.
Why are microscopes important in medicine?
Medical Diagnoses Without microscopes, several diseases and illnesses can't be identified, particularly cellular diseases. Through seeing cells in their nature using the microscope, experts can observe how various foreign bodies attack cells and how cells counteract them, all from the view of a lens.
What was the primary effect of the invention of microscope to human beings?
The microscope allowed human beings to step out of the world controlled by things unseen and into a world where the agents that caused disease were visible, named and, over time, prevented. Charles Spencer demonstrated that light affected how images were seen.
Why was the invention of microscope important for the study of living beings?
All living organisms unicellular or multicellular are made up of cells. Microscope make it possible to see inside the cells that make up all living organisms. Without microscope we could not see or understand how life works. So the invention of microscope made it possible to see the basic component of life.
Why was the microscope and its improvement an important part of the development of cell theory?

Why do biologists use microscopes?
Every experiment has its microscope, and biologists often use several types of microscope to obtain overall and more detailed views (see below), as correlative microscopy approaches link the different levels of observation. But advances in microscopy do not only depend on improvements in the instruments themselves.
When was the first microscope invented?
Dutch opticians Janssen and son are said to have developed the first microscope in 1595 by combining two glass lenses (one an objective and one an eyepiece). This was before the first mention of the term, which denotes any instrument used to see elements that are invisible to the naked eye.
What did Louis Pasteur discover?
Shortly after, Van Leeuwenhoek made much more powerful microscopes with magnification up to 200x (compared with 20x for Hooke's) and he observed a number of elements, including rain drops, dental plaque, sections of intestine and mussels. He is famous for having been the first to observe bacteria, which he named "animalcules", and reported his discovery to the Royal Society of London in 1673. Two centuries later, Louis Pasteur proved that "animalcules" caused disease and the first pathogenic bacteria were identified under the microscope, i.e. the tuberculosis bacillus by the German Robert Koch in 1882, and the plague bacillus by Pasteurian Alexandre Yersin in 1894. But infectious agents such as viruses – a thousand times smaller than bacteria – remained invisible. So Louis Pasteur developed the rabies vaccine knowing that a transmissible agent was responsible but without ever seeing it (the virus was only observed in 1962).
What is Olivier Schwartz's research?
Olivier Schwartz's team was behind major discoveries concerning the "relationships" between the AIDS virus and its target cells (CD4 T lymphocytes, see image) and is also looking closely at emerging viruses, such as chikungunya or Zika.
