- ✓ CAUTIONS: If a pupilometer is not used, the center of the lens may be in the wrong spot, and will cause the person to be unable to see; glasses may be fit poorly and cause physical discomfort, eye strain and fatigue, and headaches. When measuring pupil distance where accuracy matters, don't rely on measuring by hand with a ruler; take precise measurements with this measuring tool.
