Step-by-step explanation:
Microscope is an object used by scientists and students in many different areas of study. A microscope is used to see the tiny and very small objects which cannot be seen by the bare or naked eye. A high intensity lens is mounted on it which magnifies the object several hundred times. Usually a microscope is used to see cells of animals or plants, or other tiny objects.
Now using a microscope is not a big deal. Young students who are using microscope for the first time, I would advice them to open both eyes before placing their eye on the microscope. With the passage of time and with practice, one can learn to block the eye which is not seeing through the microscope. Also the microscope has to be adjusted with a dial on it to see the objects properly.
