Hamster left eye is cloudy

[Kevo]

So long story short, I just got off work and noticed that my hamsters right* eye is cloudy. It wasn't like that 2 days ago when I last saw her. She's still acting like her normal self eating, drinking, running on wheel, etc etc. I read that it could be a cataract but I just wanted a second opinion before I decide to bring her to vet which could possibly stress her out since she's still a little young
