The exploration of microscopes has led to numerous discoveries, without which we would be left with the limited knowledge our eyes give us. The advance of a scientific field often parallels the invention of instruments that extend human senses to new limits. A microscope lets the user see the tiniest parts of our world: microbes, small structures within larger objects and even the molecules that are the building blocks of all matter. The ability to see otherwise invisible things enrich our lives on many levels. Doctors can diagnose and treat diseases better, scientists are able to reveal links that help put criminals behind bars and make our world safer by examining the strength of bridges and other structures. Students also use microscopes to gain knowledge of the world around them.

The development of the standard microscope at the end of the 16th century would lead to a great step forward for science, particularly in biology and medicine. Thanks to these fascinating devices, man has been able to discover the wonders of the human body and study myriad ways to improve and protect it with medicinal treatments. The first scientific results based on microscopy dealt with the circulating blood system and changed our view of the human body. Scientists have also discovered and explored life's own building block – the cell. Different types of bacteria and the following struggle against diseases, as well as studies of different materials and their qualities are other valuable results.
