Polarized Sunglasses And Fish Finders

Recommended Posts

When I wear polarized sunglasses, I have a hard time reading the black images on my fish finder.   Often I have to take the glasses off to read the data.  I have the same problem with the display in my car.   I haven't seen any discussion about this, and wonder if others have the same problem.  

 

I wear Cocoons.   Would a higher quality polarized lens help?   I usually use amber lenses.   Would another color be better?  Any suggestions would be appreciated.  Thanks.

I believe that's just nature of the beast when it comes with polarized lenses. Iv had two pairs of Costa Del Mars. Both plastic and glass lenses. Both do the same thing on me.

It has nothing to do with the lense color.

LCR screens have the pixels aligned at 90 degrees either from left top to right bottom or right top to left bottom.

 

Your polarized lenses are aligned horizontal-that is how they reduce reflected glare.

When looking at the screen directly, you are loosing about 1/2 of the light transmission.

If you tilt your head either left or right, you can align your glasses with the display so it will look brighter.

 

That last time I checked a lot of sonar displays for the polarization affect this is what I discovered:

Humminbird and Lowrance displays are aligned from top right to bottom left.

Garmin displays are the opposite.

 

If you have your L or H display to the right of the console you tend to tilt your head to the right when viewing the display. That will make the display darker. To offset that, tilt your display some with the right side lower and your screen will darken less. The more tilt, the less light you loose.

Its the quality of the lens, the better the quality the more difficult to see certain digital images., especially mono chrome displays. When I'm buying sunglasses after putting them on I look at the POS card reader, if I can see it plainly them the lens is crap and won't block the glare of water. So what you're experiencing is a good thing.

What Wayne said ^^^^

 

Don your polarized sunglasses then look at this same computer screen.

If your lenses are polarizing, you'll see a black, basically illegible smudge.

The brand or quality does not affect viewing a lcd display.  I could not see my nav screen on my last car without facing it head on.  On my new car I see the screen from any angle using the same polarized glasses, must be using a different kind of glass.  Same make and model car.

I believe you post proves it does, could only see it head on, newer version all angles.  The old monochrome displays are the absolute worse when it comes to viewing through polarized lenses, the screen will be black.  The privacy covers on computers that look black are nothing more than a giant polarized sunglass lens aligned with the screen.

From my experience all the polarized sun glasses that I have ever worn do that. I think it's just the nature of them

Same glasses with different cars tells me the difference is the glass used in the LCD display.

Same here. Also have trouble when using my phone when it has a plastic screen cover on it. Going to try glass screen cover and see if that makes a difference maybe?

The polarized lenses I use also create a problem for me when using my digital camera. Holding it horizontally, no problem, but when I turn the camera to the vertical frame, all I get is a black screen. Having to always take them off to take pictures. But they are still worth their weight in gold.

The different results from polarized lenses is interesting.

Some see best when viewing head-on, for some it's the difference between a portrait and landscape screen,

for me it's something else. I tested two different pairs of polarized sunglasses.

When I view head-on I see an opaque black smudge on both pairs.

When I tilt my head back or turn my head to the side, I can begin to read the screen :Idontknow:
