Only if the IR filters in the glasses don't work on the IR structured light. You can buy dsark glasses without IR filters, but most nice ones are 99% blocking.

He said most... so 50% of glassess would be sufficient to meet Feserighi's claim.
- mikeash 9y agoDo the IR filters in those nice glasses block the wavelengths that the iPhone’s sensors use? I imagine they’re aimed at blocking the sun which is probably not the same spectrum.
- kurthr 9y agoThey are broad band IR filters because those are easier to design. Apple is likely using a very narrow band that doesn't have sun problems (see IR window from 8-14nm). https://en.m.wikipedia.org/wiki/Infrared_window https://en.m.wikipedia.org/wiki/Infrared_window However that nice band also gets filtered by polycarbonate which is common in sun and protective glasses. It also gets heavily cut by other typical IR absorbers, and creating a pass window will cost more money.
- mikeash 9y agoThanks for the info. It will be interesting to see how it plays out once this thing is released.
