The coil light I would say is the issue--- here is some info on UVB's
Which
UVB light should I use?
T
he best UVB light is a ReptiSun 10.0 fluorescent tube HO (Or Arcardia 12% in the UK). Compact or coil bulbs do not emit the proper amount of UVB light for a bearded dragon, and should not be used. Other brands, such as the Zilla Desert Series and ReptiGlo have been known to cause eye problems and other health issues with bearded dragons, and should be avoided. The reason that some UVB lights (Zilla, ReptiGlo, coils/compacts, ect.) are considered dangerous is because the wavelength of UVB that they emit is shorter and more intense than the wavelength of the "safe" lights (ReptiSun, Arcadia). UVB lights should be replaced every 6 months. The T5’s are a strong bulb and only need to be replaced once a year – the T 8 every 6 months--- where as the T 8 are not as strong—they need to be placed inside the tank the T 5 10.0 bulb approx 12-15 inches from basking spot – the T 8 approx 6-8 inches from basking spot—the cover needs to be off the bulb for full effect of the UVB rays-- I would shut the coil off and take her outside for direct sunlight if you can till you get it replaced - 15 minutes in direct sun is = to 4 hrs UVB-- you can use a plastic tote w/ no lid -- no glass it gets too hot-I would get it changed out ASAP--------------I also recommend replacing the sand -- it can cause impaction --- I recommend textured non adhesive shelf liner from your local hardware store its cheap and easy to clean - and insects cant get underneath --- is it possible she got sand in her eye as well - but my guess its the coil you have
