Opthalmic Frames
Final Fitting

Example A:
The temples touch the side of the head before reaching the ears. This is a common fitting error and can be very uncomfortable for the patient. It creates a constant tendency for the frame to slip forward resulting in additional pressure on the nose and behind the ears as well.

Example B:
There is excessive bowing of the temples causing extra pressure behind the ears. In this case the frame should have been adjusted from the end- pieces first to allow for a straighter temple alignment.

Example C:
A correct fit. Note how the temples go straight back toward the ears an come in contact with the patient only at the three points of the fitting triangle.

 

A frame may be said to rotate around three axis known as the x, y, and z axis as illustrated above. These can be useful to keep in mind in discussions of final fitting.
