lol you don’t necessarily need these but any IR reflective materials around or on your face is best. Most of the high resolution facial scanners on the market use some form of UR depth mapping and it screws out all up

I love my Kolari shades I picked up when they were running their kickstarter. Fantastic to use indoors and out. https://kolarivision.com/product/kolari-shades-ultra/

Oh and if you have need enough to worry about fingerprints, best to just get rid of them outright and deal with the rather short but uncomfortable recovery for your fingers to heal back over.
