Dynamic Dispensing Tips – I Am Human – I Make Mistakes


Just when you think that you have seen it all or heard it all.

We close at 5:30. So, you all know the feeling when you have the patient or customer coming through the door at 5:20…

This fellow comes in with the pair of glasses he picked up a few days ago and says he has been unable to wear them since he picked them up because, “When he turns his head they pull to the side.” 

Now after nineteen years in this business I must confess that was the first time I had heard that one. So, I went through my usual series of fit checks and made some modifications and he went on his way.

Three minutes later he was back again, still not right…

We went through some more changes, little tweaks here and there and asked him to bring in his other pair that he liked. He did that and we compared the two side-by-side and gave the new pair every twist, turn, angle and curve that the old ones had. He said that was better and left.

Note: the new pair had the same A and DBL as the old pair did.

Two days passed and he was back once again at 5:20 still with the same complaint. He said it was much better but it was still, “pulling”.

Made a few more tweaks and sent him on his way. Three minutes passed and there he was back again…

So, what did I do that fixed the problem and saw him happy with his new glasses?

  • A: Changed the nose pads to silicone to hold them in place.
  • B: Cut 5mm off the temple length.
  • C: Gave the temples added curvature along his head.
  • D: Added a lot of pantoscopic tilt.
  • E: Used duct tape to hold the glasses in place.

The answer is B. The temple bend was so far out behind his ear that the temple tip was acting like a lever against the mastoid bone and yes, “pulling” the glasses side to side when he turned his head.

I preach the gospel of the three-point check when selling a pair of glasses Nose Fit – Correct Width – Temple Length but as this example shows even the most experienced dispenser occasionally misses temple length. Lucky for me they were just a little too long and not a little too short!

I am human, I make mistakes, I admit them, I fix them…
