I would definitely suggest going to the vets first hand but in my experience, slight eye irritation can be solved using lukewarm chamomile tea and a cotton pad/ swab. Of course, this is only a temporary solution and due to hamsters being prone to deteriorate quickly, getting to the vet as soon as possible would be ideal. Some precautions you can take in the meantime is ensure that you are using dust-free bedding and absolutely do not use incense and diffusers around her. Often eye issues such as conjunctivitis, especially in dwarfs can be an indicating factor to larger raspatory issues. I hope this helps!
