An improperly measured inter pupillary distance (PD) may result in...

induced prism in spectacle lenses
visual field defects
blurred vision
constricted pupils

The correct answer is: induced prism in spectacle lenses

An improperly measured inter pupillary distance (PD) may result in induced prism in spectacle lenses. The inter pupillary distance is crucial for ensuring that the optical centers of the lenses align properly with the patient's pupils. If the PD is incorrectly measured, it can lead to the optical centers of the lenses being misaligned with the patient's eyes, causing induced prism in the lenses. This can result in visual disturbances, discomfort, and potential binocular vision issues for the patient. Therefore, ensuring an accurate measurement of the inter pupillary distance is essential in providing optimal visual correction through spectacle lenses.
