We all know that sinking feeling… the one you get when your patient puts on their new glasses and they make a face, or immediately reject their new Rx. Cathy asked if I would begin a monthly post about tips, ideas and trouble shooting Rx problems and glasses changes.
So for the next year I’ll be making a contribution the last Wednesday of every month. All I can share with you is twenty years of experience so trust me, I am not a “know it all”… If I had all the answers I would not be writing this blog post I would be sitting on the deck of my yacht in the harbor at Monte Carlo sipping an espresso. This month I figured I would start with something that happened just this week.
A young lady came in last week with an Rx of -3.00 OU and a PD in the fifties.
She was probably about 25 – 30, attractive and wanted a pair of classic aviator sunglasses from one of the top designers. We discussed lens options and after discovering that the new tintable poly is not available yet from our supplier I went with a 1.60 instead.
I ran the job on the edger, which probably was about due for calibration (it was). Tinted them a nice UV-Grey 80% and went to mount the lenses. The combination of my lens size being off by one or two hundredths of a millimeter, edge thickness, base curve, frame base curve and sheer lens size made it impossible to get the screw started in the frame with the lens properly seated in the bevel.
So, what did I do?
I did something that I have done many times before.
I grabbed a 1.4 tap-and-snap screw and threaded it in the eyewire. Because tap-and-snap screws are quite long this allowed me to slowly, thread by thread, tighten the eyewire around the lens while holding it in the correct position and getting it seated in the bevel.
I got the lens seated, the eyewire screw fully tightened down, snapped off the screw with hardened cutting pliers and carefully finished off the cut with the screw deburring tool. Job done!
This is also a great way of dealing with difficult plus lenses that want to pop out of the eyewire while you are trying to mount them.
