Some people wear spectacles to correct their vision defect how should they work with microscope in a lab class

d. they may either put on their spectacles or they may take off their spectacles  

Explanation:

• The microscope is an optical instrument used to increase the visual angle of near objects, which are too small to be seen by the naked eye.
• Eyeglass wearers who need single lenses with spherical power can use the microscope with or without glasses, provided the diopter adjustment of the focusing eyepiece is sufficient.
• However, if you need toric lenses, e.g Lenses that refract light horizontally and vertically differently, you should use your glasses for microscopy, because your eye has asymmetric aberrations that cannot be compensated by diopter adjustment alone.There is a test to check to know whether you need lenses or not.
• Based on the test it will be known where they must put on the spectacles or must remove them so option d is correct.
