I have a customer who has been wearing the same pair of glasses for over 5 years (purchased elsewhere). She recently had an eye exam and the Dr. did not change the prescription (she presented both her current and her prior prescription dated 1999). Her prescription is:
OD) -6.50 -3.25 x 110
OS) -7.25 -2.25 x 43
I took her monocular pd, it is 29/30.5
Her prior pair of glasses are 1.67 index.
I made her new specs in 1.7 index (hoya).
My customer picked up her new specs about 10 days ago and came in last night complaining that her left eye socket occassionally aches. She said that on some days, she feels great and sees great and yet on other days, the area around her left eye can ache (either a dull ache or much more severe). She said that when her eye is aching, if she puts on her prior pair of glasses, the ache goes away within 10 minutes.
She also complains that when she closes her left eye and moves her head from side to side, she has no problem seeing through her right eye. On the other hand, when she tries to do the same with her left eye, she feels that she cannot see through the periphery of the left lens. In her prior pair of glasses, she doesn't notice this.
I have compared PDs in her old and new specs. The PD in the left eye (new specs) is 30.5 compared to 31 in old specs.
The vertex distance is equal between her old and new specs.
Parabolic curve, panoscopic tilt equal.
Base curves equal.
Her old specs were metal with a strap bridge and so fit low on her face. Her new specs have nose pads...they also sit low but, it is only slight and she is looking more through the center of the lens than the upper quadrant (by about 2.5 mm). She also "complains" that her distance vision (i.e. while driving) is fantastic...much better in her new specs...while reading and intermediate vision is not as good in her new specs. I attribute this to the fit of the specs as described above. (Please note: she wears a seperate pair of specs for extended reading)
Honestly, I feel I have checked everything on these specs. I think I have told you all of the variables between her old and new specs...soooo...Have I missed something with this customer?
Thanks for your help,
hip chic
