Polarized glasses?

[look 171]

I have had polarized glasses before, only this is the first time I looked into my computer screen with it on. I notice one lens (right) is black and the other much much lighter. The right side is to the point where I can't see through it. I have serious double vision with these glasses on looking at the screen with both eyes. Am I missing something? When I look elsewhere in the room, everything is fine. I have to try to watch TV and see what happens.

You may have polarized glasses built for watching 3-D movies on screens. One glass is then polarized vertically and the other horizontally. The light from your screen may be polarized also in primarily vertical or horizontal direction. In that case you would see the screen bright through one lense but dark through the other.

I don't think they are made for watching TV. It is from a sporting goods store. Good old Ray-bans, I use for driving. I just find it really strange when I look over at my screen as I walk into the office. My knowledge on polarize lens is zero.

That's what's happening. What you have there is a crappy set of glasses. If you look at a computer screen or pretty much any LCD, ipod, ipad, etc.... and tilt you head side to side, you'll notice that the screens will shift back and forth from dark to light. I've had several pairs of polarized sunglasses and they've always had both sides in sync with each other which is how it should be. Yours are out of sync.

My sunglassed are polarized. I love em and have had the same style of sunglasses for 25 years. If I go into a store that has the B&W credit card reader the screen of the reader is just black. I have to take my glasses off the see the display.

I don't wear sunglasses indoors, but I do have a cheap old laptop in my garage I use to play Pandora internet radio. I can see the display on that just fine with my polarized glasses.

try looking at a cell phone screen with them on. very frustrating. if you take those same glasses and rotate them while staring thru the lenses..you will see the dark spot come and go, and even move locations.

polarized light rays are thin and long..that is why you can rotate a polarize lens filter to futz with the amount of filtering you want to achieve.

now i only wear them fishing, or where glare is a major problem. my last pair, i got standard lenses and it was very liberating.

Polarized glasses are great for protection, but not good for viewing any kind of display. I have a pair of non-polarized Ray Bans, which I use on my motorcycle because I can see my digital display with them with my helmet visor up or down. Polarized glasses mess that up.

Polarized sunglasses are considerably more effective than non-polarized sunglasses at reducing glare. Glare is what makes bright sunlight so stress full to our eyes. In other words, I highly recommend polarized sunglasses.

The way to tell whether sunglasses are polarized is to look through them at an LCD display. In one orientation, the screen will be easy to see. Rotate them 90 degrees and the screen will disappear. Polarized sunglass lenses will typically both be polarized in the same direction. Yours, look171, appear to be 3D glasses as porwolf mentioned.

I agree Rick. The visor on my Arai helmet has some type of poarizing on it as well. It always irritated me on the GS, since I only wear polarized Costa Del Mars....

Take two polarized lenses and put one in front of the other and rotate one and see what happens.

I can see the display on my Garmin GPS just fine with my polarized sunglasses on.

I can too. But you won't be able to see a quartz display with them. My bike's cluster is digital quartz.

Your bike is too new. Get an older bike with analogue gauges

Put some Scotch tape on one lens and see what happens.

Radial polarization

circles- not lines

Have a similar issue with the NAV screen one of my vehicles...tilt head/glasses 45 degrees either way and the display re-appears. Frustrating.

Most display manufacturers are aware that sunglasses are polarized and they rotate the polarized LCD displays to match. One of my garmins had the display rotated wrong, and there was no seeing it with the glasses on. I only wear polarized.

What if you tilt your head side to side. Does the display dim?
