I'm no optics expert, but considering the large width of the emission spectra of LEDs (https://www.comsol.com/blogs/calculating-the-emission-spectra-from-common-light-sources/ https://www.comsol.com/blogs/calculating-the-emission-spectr...) and OLEDs (https://www.omicsonline.org/open-access/exploiting-the-potential-of-oledbased-photoorganic-sensors-forbiotechnological-applications-2150-3494-1000134.php?aid=77020 https://www.omicsonline.org/open-access/exploiting-the-poten...), I'd say it's physically impossible to block their light to any acceptable degree of specificity.

  I am no expert, either, but it seems you could create material that will attenuate OLED-originating light much more than other light. Ie. these glasses would not be completely transparent, they would be somewhat grey but would be much more opaque for OLED light than normal continuous spectrum. Even with polarized glasses you don't block all light, you block some and due to proximity to much more luminous sources (as seen through glasses) it appears dark.

hey dreamcompiler! I'm with the team behind the glasses. It sounds like you might know a thing or too about optics. We're looking for engineers and researchers that can help us solve the hard problem of blocking OLEDs for our next product. A lot of people think it’s impossible but we’re willing to give it our best shot! Any chance you’re someone that can help?
