My bearded dragon has gone black all over it's body!!

My bearded dragon has gone black all over it's body should I be worried? She hasent moved from a sat up position for at least an hour now that I've been watching although she doesn't move oftn anyway. Also her eyes look droopy and half closed. We did, however, have problems with her eyes when we first got her although they did seem to get a little better as she's been growing. I know it's natural for their beard to turn black from time to time but should her whole body be turned black?! She's about 1 year old only about 4in long (including her tail about 7inches) and In a 48in vivarium. She has Reptiglo 10 UV lamp, a basking spot set to around 100 degrees. She is fed small locust and some greens. Please give me some advice I'm worried something may be wrong with her ): thankyou.

its the reptiglo change to the reptisun 10.0 the reptiglo has been known to cause eye problems and make them lethargic (talking from expirence)

Thanks alot I will get a new light for her. Does this explain the black colour she's gone though? She been in the viv for months now and her body has only just turned this dark. I'm worried she may be sick :S

yea its fine its just that shes stressed she should be fine as soon as u switch to the new light

She's a year old and only 7 inches long????

Did I read that right?

are you sure shes 1 year old? 7in is really small
