How important is PD accuracy?

It is important to have an accurate pupillary distance measurement when ordering glasses or contact lenses, as this will ensure that the eyewear is properly aligned with the eyes. While pupillary distance can remain relatively stable over time, it can also change on a day-to-day basis. Factors such as fatigue, dehydration, and certain medications can all cause the pupillary distance to vary. As a result, it is important to measure the pupillary distance each time glasses or contacts are ordered.
