I woke up today feeling better, however, in the middle of the day, I experienced light-headedness accompanied by headache. I bet it must be associated with my strained eyes again after minutes of staying online. I even made adjustments with the monitor's brightness and contrast features but it's still the same. It even got worst when I wore my eyeglasses which had long been prescribed to correct my being "myopic". For that certain reason, I decided to sleep hours before lunch. I was quite relieved when I woke up until now but...I still need to get an eye check up the soonest possible time. Better yet, I need to take some extra time away from the computer too! I guess that would really be of great help to me.
