Once, I saw one in my peripheral vision
, and it was followed by a severe headache. I have also seen what
looks like a shooting star. Just a small particle of light falling. Today, I was sitting down at my computer and saw about 8 sparks spread throughout my vision. They only lasted about 20-30 seconds. It was also followed by a headache, but I always have a constant, mild tension headache.
I have no insurance and I lost my job, so I can't really afford to see an eye doctor.
