My girl is due to shed soon so I've been looking out for her eyes to go cloudy. The other day, they turned cloudy but it was more like a greyish green color rather than blue, and it cleared up pretty much the next day. This doesn't seem like normal shed process, but it's been a month since she last shed and her skin has been getting dull, and her belly scales turned pink, so everything else is consistent with the shed process.
(She's about 4 months old and this is only the second shed since I've had her, so...)
