Here's what we know of the eyes:

1) They are super rare.

2) They are tied to genetics.

3) They are Super Effective against Grimm, so much that a total rookie by Hunstman standards can cripple a Maiden and petrify an Ancient Dragon Grimm in a literal flash, with the only consequence being ending up KOd for some minutes/hours.

4) On that note, depending on how you interpret Salem's words in V4E1, they are either Super Effective against Maidens, or against Cinder because she has a Grimm inside her.

"How you interpret", because Salem's choice of words is basically that the eyes hit Cinder hard "because she became a Maiden", implying they are effective against Maidens, but the way she got them was not the normal way, and she did it with Grimm Magic on top of it.

And that is literally all we know, and we don't know a single bit more because Miles and Kerry don't give a shit about them except to provide cheap miracles.

And Ruby herself gives even less of a damn about them, never asking neither Qrow nor Ozpin, even while Qrow was explaining that Tyrian was after Ruby because of her Silver Eyes.

Honestly, it's like the Silver Eyes were a last-minute thought, but unlike when Monty threw in last-minute ideas, the plans were barely changed to accomodate them. They way they're treated is worse than an afterthought, despite how Game-Changing they are.
