Eye turns weird bluish color, eye problem or shed?

I noticed over the past few days that my 6 month old bearded dragons eye turns a weird bluish color for a split second and then goes right back to normal. I can't figure out what exactly is happening or why it's happening. Her head just finished shedding last week so I don't know if there's a piece of shed in the eye that Covers it causing it to look like that or if something is wrong with the eye and it's actually changing color. It's so fast when it happens, it's literally happens in the blink of an eye! She is currently being treatsd for gout and is just starting to show progress. I have a 100 watt mega ray 12 inches from basking rock and a t5ho 10.0 reptisun. She is on reptile carpet and her temps are 105 in basking area, 85 in middle and 78 cool end.

I was taking a video today and happend to catch the weird eye action and took some still shots from the video.

Here's her eye normally...

Here's the eye as it changes, within 2 seconds it's back to normal [XIMG]93630 4647276080[/XIMG]
What the heck could be causing this?

Thanks

Looks like the nictitating membrane. It’s a translucent eyelid many animals have....perfectly normal.

Oh that's a relief. Thank you! I was wondering if they had some type of membrane that they can cover their eye with. I searched the internet for information but of course couldn't find any detailed information on the bearded dragons eyes. Thank goodness for beardeddragon.org lol

Thanks So much!!
