Hello!

As the title says, my left eye is blurry most of the time, and it has a weird spot in my peripheral vision (looks a bit like a circular afterimage). I went to an ophthalmologist, two times, and they see nothing wrong with my eyeball itself. So naturally, I think I have brain cancer/tumor now, because what else could it be. :(

If it doesn't go away in a week, I'll have to push my doctor to examine my brain or something, but I'm terrified!

Sorry for being annoying, and thank you for any advice you may have.
