I've been really worried about Trevor lately. Starting about three months ago I noticed she was missing a lot when she would go after her roaches, and she would usually only strike at them when they were crawling around the wall of her tank outlined against her substrate. Then starting about three weeks ago, she just stopped eating altogether. At first I thought she was just impacted, so I did the impaction treatment and got out a huge mass of nothing but cocofiber; no insect bits. I thought that was pretty strange, but even afterward she wouldn't even look at her roaches or crickets. Yesterday I force-fed her a worm, and she did pretty well with that.
Tonight after working about 15 minutes to get her to eat (I hide so she can't see me and just reach in with tongs and dig the dubia roaches up when they burrow). Then I turned a pretty bright light on her so I could look her over, and noticed her pupils didn't constrict. Turned it off and on several times and got no flinch like normal and her pupils didn't change at all.
Then I took one of the silversides I have for my snakes (I'm familiar with them as a food, they have no salt content. Still I only fed part of one) and put it right in front of her face. She took it the second it touched her. Thing is, they smell horrible, so she wouldn't have to see to get it.
One more thing... To keep her heat up in our house during winter, she had a 100 watt bulb (It was the only way even with the heat pad, we lived in a really drafty log house and my room opened directly to outside). When I was at home I always made sure it was either not pointed directly at her or had a scarf over part of the cage so she was only getting 'twilight level' light. But then I had to leave for my last semester at school, and I'm not sure if my mother kept doing that. Could that have caused this over such a short time?

I'm thinking the pupil thing isn't neurological since she's still burrowing, eating her shed, and being generally grumpy like always. Does anyone on here have a frog with bad vision, and if so do you have any tips for feeding?? I don't want to stress her any more than I have to, and other than not eating she seems completely healthy.
