polarized vs non-polarized sunglasses

[Eleven]

Here is a fun thing to do, take 2 pair of polarized sunglasses and turn them perpendicular to each other, it blocks out almost ALL light

Or like some have said, at the gas station, or anywhere there is an LCD screen, turn your glasses 90 degrees, its science in action!

Learned that on The Mechanical Universe.

Just in case - polarized, yes.

I wear glasses so my sunglasses are prescription also. And since I do a lot of daily driving I use:

DriveWear® Activated by Transitions®

Mine are set in Oakley frames. Costly? Yes. Worth every penny? Yes.

As for the LCD remarks - yes there is a very slight issue. It normally deals with the older displays on gas pumps and really old cell phone screens. But how much time is actually spent staring at gas pumps per week. Simply look at them straight on and your good, or take them off for the few seconds required. LCD displays in cars - never had a problem with those type of displays.

It's simple...It has to do with the way the light waves are oriented. No...I didn't look at the sight...I'm a chemist and had to learn that sh.. several years ago.
