Eyepieces themselves typically do not require periodic calibration. However, the instrument they are attached to (e.g., refractometer) should be calibrated according to the manufacturer’s recommendations. If optical alignment or clarity seems off, inspection or cleaning may be needed, but not "calibration" in the standard sense.
