which of these procedures would minimize eye strain while looking through the microscope?
always wear glasses.
use the low power objective whenever you can.
keep both eyes open through the ocular.
close the diaphragm and/or condenser.
clear selection

Explanation:

Keeping both eyes open while using a microscope prevents the eye not looking through the ocular from being strained due to forced closure, and reduces overall eye fatigue from uneven muscle use. Wearing glasses is not necessary for all users, low power objective use relates to magnification not eye strain, and adjusting the diaphragm/condenser controls light, not eye fatigue.

Answer:

Keep both eyes open through the ocular.
