Pocket: more bag space
Each Pocket level adds +1 slot. The bag starts small (a three-slot maximum has been seen early on, rising to four after an upgrade). Buy Pocket when your trips keep ending before your machines are full.
Eyesight: see what is inside
An uncut rock shows the cores it might turn into. The in-game description, read out in the BemmyBlock video, says each Eyesight level rules out one wrong option, so with more levels you know more exactly what you will get before you cut.
That makes Eyesight the upgrade for finishing your Index: you can pick up only the rocks that hold a core you are missing. Three separate gameplay videos describe it this way. No source has shown that Eyesight changes the odds on a room panel.
