Hi all. First off, wicked awesome site. More on that in another post. I'm here to spark opinions on polarization.
Unless it's somewhere I couldn't find, in which case please just point me to it.
My experience with polarized shades has been hit or miss. Mostly dealing with car displays. I have a monitor in my car and my old shades seemed to make it look funny, so it might be polarized itself. The actual vehicle displays I KNOW are polarized becuase they completely black out if I hold the glasses up to them & turn 90 degrees. Neither are Oakleys.
My question to yall is: are O's better at dealing with polarized or dark car displays or car monitors? I use my monitor a lot (it replaced a bunch of functions of the car), and having to remove my shades while driving to change the channel isn't cool.
i have an avic d2 in my truck and it goes black with my romeo 2 if rotated. now i dont have trouble while driving. turn your head funny it will go dark. since the polorized lens cuts out sideways light waves. if you rotate 90 degrees and lcd will go dark as they produce a horizontal wave. you will get this effect with even the best lense. purple windshields, green shingles on roofs. bubbles in glass on cars/ buildings its all good. the glare protection is worth it.
It varies pair to pair. The actual alignment of the filter in the lens is random, to the point where some glasses are useless because the filters are perpendicular to each other. If you have more than one pair of polarized glasses, try them all, and see which ones affect it the least.
As far as comparing other brands: Costa del Mar makes a badass polar lens (in glass). They are heavy and not very stylish, but I just got back from a 10 day trip on a catamaran in the BVI, and I never broke out my Polarized Flak Jackets in favor of the Costa's. They also seem do deal better with the weird red mirage effect on water when the sun is low.
I'm in my car apr. 5 hours / day and have some lcd-displays. I solve the typical polarization problem by tilting my head a bit to the right side, when I have to look at them.
Any polarization filter will give problems with pretty much any lcd-display. Difficult to explain in a few words, but it has something to do with the axes of the light rays that are blocked by a polarization filter (in sunglasses) and the light that comes off a lcd-display.
The oily effect you see on your iPod, is the internal tensions in the display cover (usually a plastic material), that are made vissible with the use of a polarization filter.
As far as I know, LCDs use polarisation to create the visual signal. I'm not an expert for this, but when two filters come together at the wrong angle, it's gonna be dark...
When they cross eachother at a 90 degree angle, it's not dark but black...blocks all the light. LCD displays have either a 45 or 135 degree angle and polarized sunglasses 90 or 180 (never realy could keep them appart)
That's why you can see more when you tilt your head a little.
Hey Lisandro, that is really cool. Did you do that yourself? I too have been classified as a visual learner (or stupid according to one teacher I had LOL) and that pictorial you did made perfect sense. Thanks
O yea...so my conclusion is: All polarized lenses will do this. No matter what brand. But Oakleys are better because a lot of other competitors add layers and layers into the polarized lenses. This causes distortion. Oakley polarized lenses are created by liquid infusion. Causing no distortion and giving you no headaches as your eyes dont need to be looking through layers.
