(Worry) I'm concerned it might be cataracts.

Hello, since the theme of this event is cataracts, I was a bit worried and wanted to share. My eyesight has slightly worsened compared to before, around 0.3, and sometimes I see foggy, blurry vision as if there's a mist. People around me say it's because of fine dust lately. I looked into it and found that the causes of cataracts include outdoor UV exposure, but I don't spend much time outdoors and mainly use a computer and phone for work. Can these also be causes? I'm worried, so I think I should visit a hospital, right?
