Why is an Accurate Pupillary Distance Measurement Important

Is an accurate pupillary distance measurement important in the making of eyeglasses?

When taken correctly it ensures the proper focus when a patient looking through the lenses. If the pupillary distance is not measured accurately it can cause eye strain, headaches and unclear or double vision. All lenses have an optical center that must match the patient's pupillary distance. After the eyeglasses are made, an Eyecare professional verifies the prescription and all given measurements to ensure accuracy. Optical centers of lenses must match patients pupils where the focus is the clearest

All prescriptions require a precise measurement to ensure the quality of the optics. A quality inspection will guaranty the measurements were taken properly.
