Polarized sunglasses and dark LCD screens
May 15, 2017 20:58:00 #
What a crazy discovery: with both my new cameras (Panasonic Lumix G7 and Olympus EM10 Mark II), if I am wearing polarized sunglasses and turn my camera past 45 degrees, heading to a vertical orientation, my LCD screen becomes too dark to see!
I've researched and it's part of the LCD construction - can even be found with some televisions. Thankfully, my "issue" is vertical, not horizontal.
But I'm curious if anyone has ever heard of this or had a camera affected? (I haven't worn sunglasses for a couple of decades, part of reason for my brand new discovery, I guess)

I've been aware of that for some years. The LCD monitors will darken if a polarizer is rotated in front of them. The interesting thing is that some polarizing filters are one way. They polarize light coming from one side, but not the other.

Linda I discovered this several years ago when I purchased an expensive pair of Rayban sun glasses to use on my sailboat. I was happy that they were polarized to eliminate the glinting off the water but was shocked to see that all my instruments -radar, gps, etc- were black. I am still looking for non polarized prescription sun glasses

Yes, I've seen that effect with cameras and other things. It's always a surprise. In the car, I see rainbow colors on the plastic over the instruments, etc.

I think that this is pretty common with electronic displays. My 2008 Corvette's dash (center stack) is unreadable while wearing polarized sunglasses.

So a much wider issue than just camera displays. My brother mentioned UAV (drone) screen. All these years I didn't wear sunglasses see what I missed!

I was told by a private plane pilot that Polarizing sunglasses were illegal to wear while piloting an aircraft. I believed him because I once had a vehicle with a radio that had a 3x4 inch screen to display and change settings. If I had polarizing glasses on the screen was completely black, as if the radio was turned off. I, also, had this same issue with early versions of the Garmin GPS unit. I imagine it would be hard to pilot an aircraft with black gauges.
On the other hand, I had had a couple other vehicles that were unaffected by polarized lenses. Same as with the newer Garmin devices. So someone figured it out.

Since moving to Florida, I live in my prescription sunglasses. They are on all the time outdoors, even in the pool or Gulf. I strictly use the viewfinder and if I chimp I sometimes have a hard time seeing my screen. I feel your pain. LOL!

When my cameras screens 'black out' I just rotate the camera s needed and the screen becomes again readable. Try it, then you may not need to chuck your essential sunglasses. This issue varies among cameras. John

I found that polarized sunglasses make it impossible to read many kinds of lcd screens. I could read them by titling my head 90 degrees, but at my age that is nye on to impossible. Don't buy them anymore.

Any LCD screen will be subject to this effect with polarized lenses. The same with many types of tinted glass. I see patterns in my rear window.
