I'm not clear on the eye issue either
please post to youtube and link.
I've had a panther ( my prized pet) fall and injure his eye
The "pressure valve" for his turret was burst and his eye
telescoped and radially ballooned out.
He eventually lost the eye but he's always fed fine and targeted without a problem.
Yours may have suffered a hard fall and landed on his side injuring his eye
(mine did TWICE - I blame raging hormones for his risky behavior)
Yours seems uncomfortable with targeting due to inability to triangulate
he wants to feed so it's not a problem with hunger or protests.
Is he rubbing it against a branch or something due to irritation?
Not sure what the problem is, but it sounds like a lack of vitamin A
and or physical damage at this point (video / picts please).
I would switch to another supplement maker.
Some makers may leave out or substitute nonavailable synthetics
in their formulations when things get tight.
I suggest HERPTIVITE (BLUE label)
it doesn't use a synthetic form of vitamin A
but Beta Carotene that can be bioregulated by the animal.

I would also gutload his crickets carrots with carrot shavings.
This is a conservative approach until more is learned.
I doubt it has anything to do with calcium affecting his bones
his legs would give out beforehand and couldn't hold himself up.
IF it's a problem with vitamin A (absence or non-bioavailability)
that would cause symptoms as you describe them -including loss of color.
