Maui Jim lens polarization

Postby new to MJ on Sun Mar 13, 2011 7:25 pm

Hi,

Are curved Maui Jim lenses (or curves lenses in general) supposed to polarize like this?

I bought MJ Pilots and they use polycarbonate lenses which have a lot of curve.

compared to my P Aviators which have a flatter lens:

Hi,

Thank you for the post. The pictures that you sent are of normal polarized lenses in front of a computer screen. The effect of the lens against LCD screens like that shows the characteristics and nature of that filter. This is why it is not recommended for pilots to wear polarized lenses while flying. All polarized lenses no matter the curve of the frame of lenses will look just like that.

Let us know if you have any other questions or concerns.

Again, I have been wearing polarized lenses for years. Each brand and models polarization filter acts different when I do the computer screen test. This has never bothered me, but I understand if you are not happy. However, I do not think it's a defect. I would suggest you take the sunglasses back to the retailer and exchange for another one. I hope this helps.

I have looked further into the polarized filter being the way you described MJ and larumd is correct. With Maui Jim Sunglasses it is possible for the polarized filter to be at a different axis instead of the same, which is why it causes them to look different when conducting the computer test. Maui Jim will be able to also explain this to you and let you know that it is normal. Since Maui Jim Sunglasses have such powerful technology it is imperative that they inspect all their products thoroughly before they are shipped out. I hope this helped you out.

THIS IS NOT THE WAY IT SHOULD BE

Had the same problem. It is a factory defect that Maui Jim does not want to admit.

Basically when they bend the lens they damage the polarising filter. That way filter has non consistent polarisation angle and most of all does not cover the whole lens. This results in darker and lighter colours of the sky in the sunny day http://img716.imageshack.us/img716/8749 ... 9large.jpg
, it also results (which is especially annoying) in all sorts reflections being visible or not by one aye only http://img830.imageshack.us/img830/6510 ... 7large.jpg . The feeling is like someone would constantly play with a sun reflections on your ayes and is very distracting.


Changing the [link=http://www.opticsplanet.com/rx-eyeglasses.html]glasses[/link] does not help, some Maui Jim models just have it. Arguing with Maui Jim does not help.
After six months and hundreds of telephones I got an explanation on paper:
"It is the evolution lens material that will flex at the edges of the frame when mounted and optically it doesn't effect the lenses."

I seriously can't see any point in adding patchy "evolution" filter to lenses. Also the question arises if only the polarising filter is patchy or maybe others are as well.

My suggestion is - change them and choose a different manufacturer (which worked for me), or get a lawyer.

Polarisation angles are different but only a bit. I have checked that (I use polarising filters in photography), and the truth is that 20-30% of the lenses have no polarisation at all.

Maui Jim can try to explain why it is OK, but the funny thing is that you can buy [link=http://www.opticsplanet.com/rx-eyeglasses.html]glasses[/link] for 20$ with uniform polarisation and no explanation will be necessary.

gacek,

It sounds like you have a lot to talk about with Maui Jim. They should be made aware of your dissatisfaction. So far they have been an ideal manufacturer to work with and they stand behind their products. I have also found that they are good listeners.

Good Luck!

What this thread is speaking of is bifringence and it is a defect in the lens upon mounting it seems. The link below provides a good explanation of this effect.
