Why should microscope light be dimmed when viewing living nearly transparent cells?
Human A&P Lab manual (cat version), N. Marieb, Pg. 346. "Place the slide on the stage, and locate the cells at the lowest power. You will probably want to dim the light with the iris diaphragm to provide more contrast for viewing the lightly stained cells. Furthermore, a wet mount will dry out quickly in bright light because a bright light source is hot." The answer I believe is 'to provide more contrast'
