A few months ago, I was reading something on my monitor, and realized that part of the text seemed to have "disappeared". It's not that my vision got blurry, it's more like there was something blocking that part of the text. Eventually, that something developed into a rgb-colored "flash". I was afraid I had suffered a permanent burn or something of the sort, so the first thing I did was turn off the monitor. Eventually, the flash shifted positions, became bigger as it moved to the outside of my field of vision, then eventually seemed to go away, but I felt as though my peripheral vision wasn't all there. After a while (an hour or two) the phenomenon had ended, leaving me with a mean headache (not severe enough to be called a migraine, though). After this incident, I started using my monitor at a lower contrast setting, and taking periodical breaks. The flashes reappeared one other time a few days later, and again a couple nights ago, but this time I identified them early and all I needed was to step away from the monitor for a half hour or so. No headache this time, either. I had chalked all this up to eyestrain from the hours I spend working at my computer (the flashes have only appeared while using the computer), so I wasn't too worried. However, today I looked up at the clear sky and saw several "floaters", which frightened me, since I'd only had one that I knew of, and it'd been there since I was a child. Looking up, I saw about five, which I can't see at all except when looking at the sky. I did some reading on the net, and found that while floaters and flashes are not always symptoms of retinal detachment, they can very well be. I know I should get an eye exam to rule it out, but I won't have the money for it for a few more days. In the meantime, if anyone has experienced this, and could tell me what to expect, I'd really appreciate it.
