Polarized lens question

**jherman** · 08-09-2005, 03:39 PM

I have a customer who tells me his new polarized lenses work well monocular, but not binocular. What he is explaining sounds like glare. He has also indicated the brighter the sun, the worse the glare is. I will check the alignment of the PVA, and the usual VA trouble shooting when he comes in next week.

I was just wondering if any members had run into this one before?

What is the frame style? If it is a wrap let me know. Also let me know the Rx the base curve the frame is designed for and the front base curve of the lens used.

What is the fitted vertex distance of the frame?

The brand of polarized blanks if you know and the lens material.

With this basic information I may be able to guide you on what to check first, second and third.

Here at ICE-TECH we specialize in high quality polarized lenses and compensate for the changes required for the wrap, pantoscopic tilt and vertex distance.

Sounds like a stress issue....lens is a little big in all the wrong places and before you know it you will a visible strain marks coming in from the edges..i have seen this problem a dozen times.

CDot has a good plan, but also see if the polarization is on axis. I have seen "reputable companies" put out Rx and non-Rx polarized lenses 90 degrees of axis. This results in glare in one eye and not the other.

Definately check the axis of the polarization. I had a pair that was off axis in one lens in one direction and the other direction in the other lens. They made me sick to wear them!

Actually did about 35 years ago................one lens was mounted off axis..............was pretty simple and corrected.

:D :D :D

I remember making a pair like that once. I think it was the morning after the night before and I wasn't feeling too well. Anyway I caught it, the patient never seen it.
