From that second video there doesn’t really look to be anything wrong
#Potential vision issues
flat vigil
The first video kinda just looks like she’s like 
wtf is happening
Kinda stunned
She’s not really moving much in that video either which is why it looks more like a “wtf is going on” kinda thing if that makes any sense
During brumation most of them do not eat
They’re asleep
They refuse food etc
She’s older yeh?
It may be possible it’s just an age thing but some leos seem to just have eh sight with bugs in general. I know my 3 sometimes struggle to discern what is a bug and go for the tongs
I have to shove a bug in apricot’s face cus she tries eating everything else otherwise lol
If she’s up and active I wouldn’t really say she’s in brumation
How long that been goin on
Hmm. Brumation season is coming to an end soon so idk if leos would choose to brumate this late into the season but I only have experience from Timbit that has been brumating since October 
I don’t think it would be hazardous but I don’t know what you would get vision wise from bloodwork
She really does look okay in the two videos
One she just looks stunned and the other girlie just walkin
You’d have to assess quality of life at that point
I imagine it varies per individual
I don’t know many blind leos
If it helps
Apricot will follow my hand and then if I move it continue to stare in the direction it was first in
She uh. Doesn’t catch on that it moved right away
