if you have a good vet in your area, maybe he could give you some advice on your glider and if her eyes are sensitive to light.
I have not seen a glider sensitive to light, but we have some that just are not into bonding with us all the much, we have some that are very bonded and nice with no biting and no running away and we can pick them up. we have 2 other that only want to be near us for a treat or during playroom time.
The best I can suggest is to keep up with the bonding, but also I would recommend during daytime when they are sleeping put your hand in the sleeping bag and let them sleep with your hand for an hour or so.
I also saw a video were with young gliders the girl would get the glider to pee on her hand, rub it around her hands, then get the glider to stay in her hand, and that seemed to really help with her bonding on young gliders.
