The trick is which way the filter runs. Most LCD and LED-backlit panels emit vertically polarized light and ordinary sunglasses are cut to pass exactly that, so this pair turns its filter ninety degrees and a television reads as a flat black rectangle while the room around it looks normal. Ivan Cash and inventor Scott Blew modelled them on the sunglasses in They Live, raised $140,920 on Kickstarter in 2018 and shipped in 2019. OLED phones are unaffected, IRL Labs is now sunset, and the V&A has a pair.
