Step 2. Cutting a Polarizing Film

Most LCD monitors’ glass is covered with two films, a polarized one to filter out the light you are not supposed to see, and a frosted anti-glare film. We don’t need the anti-glare film. We’ll use the polarized film only for our glasses.

Grab your cutting knife and cut the films along the edge. Don’t be afraid to press hard. The metal will not scratch the glass unless it’s covered with sand or other abrasives.

Recommendations: The coverage of some monitors is not bonded. Sometimes you can just remove the protective metal edge of the matrix and get the films without cutting them out.
