I'm not familiar with them, but one of the comments in the Kickstarter mentions this company as source of "daylight" (non-UV) resins: http://www.photocentric3d.com/#!daylight-resin/nen21 http://www.photocentric3d.com/#!daylight-resin/nen21 Perhaps not coincidentally, these resins seem to be sold in less photogenic opaque black bottles, but this does make it more likely that a resin actually exists. The part of the article that bothered me more was the explanation of the principle of operation: At the bottom of the reservoir, there’s a piece of polarized glass which you place your phone underneath, facing upward. The polarized glass then takes all this light (which shines outwardly to give your phone a wider viewing angle) and redirects it so that all the photons are traveling straight upward. I don't think that's how polarizing filters work. But perhaps this is just an issue with the 3rd party reporting rather than with the product itself.
