What are frame fitting parameters?
Once the patient has chosen their frames, frame fitting parameters can ensure the frame style and design doesn’t hinder clear vision. Everyone’s physiological and visual behaviour is different, and so frame fitting parameters are there to make sure the frame fits while delivering optimal vision. These measurements include pantoscopic angle, dihedral angle and back vertex distance.
Measurements are taken while your patient is wearing their chosen frames, making sure measurements are accurate to how they would naturally wear their frame. Frame fitting parameters can therefore help you to achieve a more personalised lens service.
