Polarized sunglasses work by...can anyonepick an answer below  explain it so i understand better?

The process of polarization is to bend a ray of light as it passes through a lens. To bend a ray of light is to make it less harsh on the eye.

Can you be more specific? Every material has it's own index of refraction....and none of them work out to nice even numbers. (well, hardly any of them). Is this all the questions says? I looked around on some websites, none of which made this question any clearer. Good luck!

Of course they'll work. The question is if you will see them. You can't travel at the speed of light, anyway, or physics is wrong, so nobody would be able to give you an answer. \n\nAssuming you were just really close to the speed of light, you would still see them. Einstein discovered that the speed of light in a vacuum is constant to ALL observers, no matter how fast the source of light is going relative to the observer. So at any speed, you can see your headlights just fine.

It's a FresnelC function.  Check out the link.

Assuming that the light incident on the first polarizer is unpolarized and has intensity I0, the light transmitted through the first polarizer is then half of I0. This is then incident on the second polarizer so that is positioned usch that, neglecting any losses, all of it is transmitted. The initial state than see 0.5*I0 coming through polarizer 2. \n\nOne of the polarizers in then rotated through an angle q. This rotation causes the output to be reduced by 41%\n\nIout = 0.5*I0*(1 - 0.41) = 0.5*I0*(0.59) = 0.295*I0\n\nThe law of Malus says\n\nIout = I0*(cos(q))^2\n\ncos(q) = sqrt(Iout/I0)\n\nPlugging in what was determined above\n\ncos(q) = sqrt(0.295)\n\nand solving for the angle\n\nq = 57.1 degrees

3D movies can be made using polarized light.  The projector is actually showing two frames, one polarized vertically, and the other polarized horizontally.  When you where the polarized glasses your right eye sees only the frame that is polarized for the right eye, and the same with the left eye.  This allows them to project two images (as your brain would see them naturally) at the same time and have you be able to properly interpret the 3D perspective.

The link suggests laminations with polarized films.  Good luck.

If they are the same prescription they will work the same, but you see differently out of each, just give your eyes about a minute to adjust from one to the other.  ]\n\nI used to wear glasses, but I have wore contacts for about ten years now.  I don't like wearing my glasses anymore...only before bed-time!

That's just the nature of the optics. They need to be bent in order to have you - from the front seat - see a wide enough area along the side of the car. The result is a curved lenses and distortion.

This phenomenon is call total internal reflection.\nThe theory explaining the phenomenon is detailed in most good physics optics textbooks.

they give you glasses to wear for boot camp so you dont have to worry about having a lense pop out or get dirt in it.  Trust me you will spend a good amount of time in dirt, or sand.  You dont want you glasses or contacts going through that.  Use their glasses, they are free and you dont need to worry about them breaking.  Once a year the corps will give you a free pair of "civilian" glasses, they are actually a nice pair of glasses, but you dont want them in the field.

A convex lense is made up of individual prisms arranged in such a way that the pointed axis, which is suppossed to be the top, of one is alined to the base of the other. \nWhen ligh hits the lense, refraction occurs due to the arrangement of the prisms.\nAt the principal axis, two of these prisims are facing one another tip-to-tip in which case the light does not neccessarily pass through any of the prisms itself but through the interface of the apex of the two adjoining prisms.\nThe reverse is true for concave lesnses.

your question does not really make any sense. It will be better if you could rephrase it so that we could understand.\n\nespecially this part "holes in the material are not blind"?

polarized is good because it cuts down on the glare from light reflecting off things...

Actually most of todays satellites use dual polarization. Its not unlike vertical and horizontal polarization of basic radio antennae down here. Some of the earlier sat tv systems had a parobolic dish that would mechanically change polarization to get the other 12 of 24 channels on the satellite system. Multiplexing is another technique that provides more channels.

To check for a polarised lens take a watch (digital) and hold the glasses in front of it. Rotate the glasses through 90 degrees (top becomes side). The display should disapere or some of is should dissapear.
