I enjoy programming and working on my game for hours straight but my eyes just cant keep up. After about 2 hours I start misreading things and I cant focus my eyes without strain. After about 8 hours I no longer can even read the screen without being a matter of inches away from it. I have never had eye problems before I started programming. I think it may be the font but when I tried making it bigger it just made it harder for me to browse large numbers of lines of code.
Do you wear corrective lenses? If yes, you may want to go get your prescription double checked; if no, you may want to go get your eyes checked and see if they would help you.
For years, I knew I couldn't see far away things, but thought I could see close up things just fine. I finally went to the eye doctor to get fitted for glasses a couple of years ago (I can't wear contacts because you blink less staring at a screen and my eyes dried out), and I was amazed that they helped with my near vision (I went to get them only for my far vision). I have astigmatisms in both eyes, and correcting these actually helped with both near and far vision. Despite the fact that I got them to help with my blurry far vision, I now wear them all the time because they help with my near vision too (which I never thought was a problem).
Almost two years later, I went back to the eye doctor and it turns out my prescription has changed a bit, and the right lens of my glasses is too strong of a correction. This explains why recently my eyes have felt strained and sometimes I'd get headaches.
Anyway, I suggest seeing an optometrist and just checking things out.
You could try taking a break, going outside in the fresh air and relaxing, or exercising. You could also try exercising your eyes, by starring at different locations (without moving your head, your eyes actually need to move) and statically hold it in various locations for 10 or so seconds.
After all, you do blink less when you're starring at a computer screen for hours on end.
This might not be relevant for you but I think I don't get eye strain because I tend to look at the keyboard when I type. My advice would be to give yourself reasons to move your eyes as much as possible. Maybe keep some artwork near by that you can look at in between thoughts (or just stare off into space). Manually program your mp3 playlist to only 6 or 7 songs. I suppose the majority of my suggestions would amount to introducing distractions that aren't so distracting as to derail your train of thought. And remember to blink.

Have you considered that it's not the size of the font that is the problem, but rather the color and contrast of both the font and the background?
Personally I can barely work with the default white background/black text that comes with most IDEs. In Eclipse, for example, I use the "Recogneyes" theme.
A dark background and low contrast ratio between the background's color and the font's colors can really ease the strain on the eyes.

This. My near/far vision is good enough that I can do most things without glasses, so I never had them, even though I knew I had astigmatisms in both eyes from the big halos and spikes of light I see around street lights and car lights at night. But reading my computer screen got to be more and more straining and started giving me headaches, until I finally went this year and got some computer glasses. Now I find looking at the computer comfortable for a lot longer.
