(Concern) My vision often becomes blurry, so I'm worried about cataracts.

These days, I can't look at my phone for more than 30 minutes. If I look at it for a little longer, my vision becomes blurry and foggy. I also feel a bit dizzy. So, after using my phone for more than 30 minutes, I can't do other things well. I heard that early symptoms of cataracts include blurred vision, so I'm worried I might have cataracts. I'm unsure whether I should go to the hospital.
