I am nearsighted and was diagnosed with Posterior vitreous detachments about 5 years ago. I am now 32 years old. This past year I had had a lot of vision problems. One is I will suddenly not be able to focus. My eyes hurt and I am getting daily migraines. And then I will get a shower of black dots and it makes it hard to read. I've always had floaters and I can deal with those, but these are like i was looking at 5-10 suns and I get those black dots in my vision. I have had this before. It will last for a few weeks and then get better for a while, but it has returned again.
