Yeah, you need a new UVB tube, either a 24" Reptisun 10.0 T5HO or an Arcadia 12%< and then a matching 24" T5 flourescent tube fixture. I can guarantee the reason your beardie's eyes are messed up is due to #1 that coil bulb, they always cause horrible eye damage, and #2 that sand you had. Thanks for getting it out of there...The tube UVB you have is no where near sufficient for a desert reptile. We're not saying you need a "10 watt", but rather the 10.0 T5HO which is actually 24 watts!!! 10 or 13 watts is hardly half of what a beardie needs to live. She will not survive long with either of those UVB tubes, you need to get onto Amazon.com and search " 22" Reptisun 10.0 T5 High-Output UVB tube" (their 24" T5 tube is actually a 22" tube, don't ask me why, but it fits in a 24" fixture). You can buy the tube for $24.99 or less. Once you select the UVB tube, scroll down to the package deal with the corresponding fixture they show you. This isn't optional, she isn't going to survive without it. And yes, please dust her feeders every single day with Calcium with D3 for now, until you get the new T5HO UVB tube installed, because she's not been manufacturing any vitamin D3 on her own with those UVB lights...AND PLEASE, THROW AWAY THAT COIL UVB NOW, IT'S HURTING HER EYES, I DON'T KNOW WHY THEY SELL THEM BUT THEY'RE AWFUL!
Also, do you have a digital probe thermometer or a temperature gun to measure her temperatures? If not and you're using a stick-on thermometer, you'll need to order a digital probe thermometer with a probe on a wire for $10 on Amazon as well, the stick-on thermometers are junk, and usually off by 20+ degrees!!! Once you get the correct UVB tube and the digital probe thermometer, you need to then work on her Temperature gradient.
