Polaroid Glasses

I travel at all times with my poloroid Rx sun glasses. I see no difference with them on or off. It may be a function of the type or quality of the glasses you are wearing?

I think Polaroid glasses will affect how all LCDs appear to some extend, depending on the angle. I can't wear them in my car because all of the displays are LCD and depending on how I turn my head they can black out completely.

What are Polaroid glasses? Do you mean polarized glasses?

I have the same thing happen with my sunglasses. I believe it's because polarized glasses only let in either horizonal or verticle light waves.

Polaroid sunglasses are made by licensees of the Polaroid Corporation using polarized lenses. The original patent for polaroid lenses was/is owned by the Polaroid Corporation and was invented by Edwin Land.

Try turning up your brightness setting for the backlight. The first time I wore my shades I found the screen too dark. It helped by turning up the backlight light setting to max.

Ah, I see. Ya learn something new every day! Thanks...

That's right. Polarized sunglasses block wavelengths close to the horizontal. LCDs look weird through the sunglasses because they use light polarization to work. The overlap (near 90 degrees) with the sunglasses' filtering is what appears obscured.

Yes, that is what I meant to type.

I had great problems with polarized glasses and my StreetPilot 2610. I could make the whole screen disappear by turning my head. My nuvi 650 seems to have little problem. I believe the effect is a function of how the crystals in the LCD display are oriented in relation to the polarization of the glasses.

Same thing happens with the LCD displays on most digital cameras.

I don't have any problems with my polarized sun glasses and the display on the Nuvi 660, but do have a problem with the Edge 205. Different types of displays cause different problems.

I have a Garmin 330. I have to pull my sun glasses down to see it.

I bought a 530 from Costco and the problem went away. They put the 200W on sale so I returned the 530 and have no problem seeing the 200W with very good polarized lens.

This is an issue with all polarized lenses and displays. I was worried about this very issue when I bought my first polarized clip-ons two days ago. Tried them on in the store and they matched my cell phone's display, but they are at 45 degrees one way to my laptop, and 45 degrees the other way to my GPS. 45 is not a deal breaker, but if I tilt my head side to side the computer, GPS, and radio all fade in and out in a mildly amusing manner. If it's only "somewhat" difficult, then you're only out by 45 degrees, a little tilt left or right and it'll come right in or go completely [impressively, even] black. You might try taking your receiver into the store and shopping around for a pair of shades that line up with it.

My garmin 660 looses clarity if i use sunglasses. and they are Maui Jims, some top line glasses

Light is polarized by reflection off a surface and the glasses block one orientation of polarization. That is why they reduce the glare off water or the windshield of a car.Changing the angle of the GPS should help the problem.

I have the same problem when I wear my polarized clip-ons. Even with my c340 at its brightest setting, the screen gets dark and the colors that normally appear become very distorted. Everything has a purplish and iridescent quality to it. So, when I'm wearing my sunglasses I just listen to "Jack" rather than watch him.
