How should a man wearing spectacles work with a microscope?
A) He should keep on wearing spectacles
B) He should take off spectacles
C) He cannot use the microscope at all
D) Wearing or taking off makes little difference
E) None of these

Hint: Microscope is an optical instrument, which is used to increase visual angles of objects that are nearby, which are very small and cannot be viewed with naked eyes.

Complete answer:
Microscope is an instrument which helps in viewing objects that are too small to be seen. Microscopic means invisible to the attention unless it is aided by a microscope. There are different types of microscopes, which are made in different ways. One of the methods which define a microscope is the way instruments interact with a sample to make images. The optical microscope is the foremost common microscope which uses light to undergo a sample to get a picture.
When a man wearing a spectacle operates a microscope, they usually remove the spectacles in order that they can align their eyes correctly with the eye pieces of the microscope. Only then they can view the magnified image.
Let's look at the options to find the correct answer.
>Option A: If the man works using the glasses, he will not be able to align his eyes with eyepieces. Therefore, this is the incorrect option.
>Option B: He should take off his spectacles, in order to view a magnified image, without having any discomfort in aligning eyes with eyepieces. Therefore, this is the correct option.
>Option C: That's not completely correct. A man using spectacles can view through a microscope when he removes his spectacles. Therefore, this is the incorrect option.
>Option D: Since wearing or taking off spectacles make a big difference, this is the incorrect option.
>Option E: Since there is a correct option for the question, this is the incorrect option.

Thus, the correct option is (B)He should take off spectacles.

Note: Eye fatigue is one of the common issues faced by microscope operators. During the beginning of the career of a microscopist, when viewing the object, the operator tends to tense up, which results in adjusting your eyes to line up the sight. This causes serious headaches and eye sight problems. As a remedy towards this, check the spaces between the eyes and then relax them into the eye pieces, without changing the eyepieces.
