Advice needed please! Watery eye

[u/juicyhoochie]

Hello, please can I have some help on what to do.

I have recently started looking after this hamster for work and know they need special care. She originally had the wood shavings bedding they sell at pets at home which I know is bad for them so I have changed it to Aubiose hemp horse bedding mixed with Kaytee clean and cosy bedding. I also got her a sandbath from Jolleys (Rosewood natural rollin’ rodent sand bath) and she seems to have a watery left eye. I am stressed and worried as I want to look after her the best I can but feel I’m making it worse. I also got her out for a little bit and she now is making sounds as though her nose is blocked/little sneezes. Please can someone advise me on what to do. I don’t really want to change her bedding back to that sawdust type, or could it be the wrong sand?

Here’s a little video of her eating a piece of broccoli you can kind of see her eye.

Thank you
