It is important to keep a microscope covered when not being used. Even when storing a microscope in a cabinet a dust cover must always be applied. By applying the dust cover to your microscope it prevent dust from getting in the eye lenses
It is important too keep a microscope covered when you are not using it can greaty prevent containation and also because it can prevent dust from gathering on the lens of the microscope. Another conclusion I have made as of why you should cover a microscope when you are not using it is that, if the microscope is close to light and it is turned at a certain angle, it can start a fire if the force of power, and the angle is great enough.
