Exaustion may be your real problem (Score 1)

I discovered while at a LISA conference that my eyesight was going bad. I couldn't see all the way to the front of the class. I went to an eye doctor and got tested. The doctor said that my eyesight was just fine. It happened again the next time I went to a conference. After some troubleshooting, I discovered that as long as I'm reasonably well rested my eyesight is just fine. When I start getting tired (or exausted as in the case when I go to conferences) my distance vision deteriorates until I get a couple good nights sleep again.

I don't know if this is your problem too, but it's worth looking into. Get a couple good night's sleep in a row and see if things start getting better.

Good luck!
