since you have a VISION series Phantom, your FPV happens via the app and wifi. So you aren't going to get goggles that receive the signal directly, however I have seen someone in the past suggest using goggles via the HDMI or video-out from the tablet.
Here's one one Ebay that claims to work with ipad/ipod/iphone, not sure what version
anyway that's the track you need to take... with a Vision series P2 broadcasting to you via the app, you need to focus on just getting goggles working with the tablet in general, via hdmi/video out so basically the goggles become the screen for the tablet, including the DJI app and everything else.
