That last bit goes for people too, it’s called Leukocoria can be am early sign of all sorts of eye disease. It’s a common way retinoblastoma (a thankfully relatively rare child eye cancer) gets caught - it shows up as a sort of white sheen in one eye in flash photos.
I know someone who had that. I remember their parents explaining how “red eye”, in photographs, meant a healthy eye and how their child had had a “green eye” which lead to the path of the initial diagnosis.
They are a healthy young adult now with a glass eye.
