Frame fitting parameters

Personalise your patients’ lenses with additional measurements

  • Integrated measurements : lenses that are made specifically for the way patients wear their frames
  • Digital measurements carried out with Visioffice or Eye Ruler for enhanced accuracy
  • Parameters to ensure vision is clear and sharp
There is so much emphasis put on having the right lenses, but it’s important not to forget about the frames. Frame fitting parameters can ensure the frame fits and sits on the patient’s face for optimal vision.


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.


Are frame fitting parameters important?

Frame fitting parameters can reduce lens power error and improve the near vision zone. Lenses without these parameters can sometimes result in a distorted field of view, as they have not been fitted precisely to suit the wearer’s behaviour. With so many different styles of frames and everyone’s anatomy differing from one another, being able to tailor lenses with frame fitting parameters can make a huge difference.
Patients now come to expect a personalised experience in-store, and by investing in the right technology you can dispense enhanced lenses that meet their needs perfectly. Along with other personalised lens options, demonstrate your expertise and deliver a service that goes above the patients’ expectations.
Frame fitting parameters can be measured with a Visioffice optical measuring system or Eye Ruler 2.
