Persistent dot when blinking

[Markstorm]

I always see a dot when i blink, near the middle of my vision but slightly toward the upper-left. I tried closing one eye and I found that this only occurs when i blink my left eye. The dot disappears after a little bit, and comes back when i blink again. If I close my eyes entirely, i see a tiny bluish patch where the dot would be, which disappears after a little bit. What should I do?

Here's another problem I have. When I was in high school, i constantly worked with a monitor on in a pitch black room. Now, after any period of computer use, I get an "afterimage" when I close my eyes. This lasts for a few minutes or more, depending on how much I used my computer.

Am I screwed?

Marstrom.  Relax, take a deep breath, relax. The afterimage is a normal entoptic phenomena and the dot is likely a floater. If you have not had an eye examination within the past two years, see an ophthalmologist (Eye MD) for a comprehensive medical eye examination and an update on your myopic correction.

Also, I'm nearsighted and have floaters. I'm beginning to be able to guess the answer to my question.
