Most electronics have the same anti-glare technology as polarized glasses. You’ll be able to test the polarization by looking at the screen. Open a white screen, because the brightness will make the effect of the test more prominent. Once you’re in front of the computer, just put the sunglasses on like you’d normally wear them. Make sure you’re sitting directly in front of the screen. It might be helpful to elevate your computer screen to eye level if it isn’t already positioned there. While you’re in front of the screen, tilt the top of your head to the left or right side of your body. If the sunglasses are polarized, the screen will appear to turn black due to the anti-glare properties cancelling each other out. If one side doesn’t work, try tilting your head to the other side. If that doesn’t work, the sunglasses are not polarized.
