I just bought a mac the other day and I am already having piercing headaches and eye strain after using it only a bit. Could someone please tell me how to increase the standard fonts of the mac without messing with the resolution. I am hoping changing the font size in general (not just with some applications like safari) will help? Does anyone have other preventative ideas regarding this? Are there any third party applications or products that might help? I already tried messing with brightness, desktop image, sitting at a distance, color, to little avail. (fyi age and eye health are not factors, I'm in my 20s and wear glasses) Thanks!
