This could also work for other IR type glasses!
I know the theme for a while was to block out the IR sensor on the Samsung glasses with electrical tape for losing sync with the TV in 3d mode. Idea was good, but the thing is was the TV is producing wavelength of "IR" that was effecting performance of the glasses.
I searched around for dielectrics to coat the lens (best solution), until I came across photography pages for creating IR filters.
Well, without this being long winded, I found using the actual floppy disc works perfect for blocking the wavelengths responsible for causing the drop outs, or sync issues. I have had 100% luck with this.
Remove the the disk from inside the cartridge, trim it to be a bit larger than the sensor window of your "glasses", and apply with your favorite "clear" tape. You can use some sort of black tape to cover "ONLY" the edges from unwanted radiation leaks, but I have had no issue with just using scotch tape.
Try this out, thank me later
