I tried computer glasses a while back, and they just didn't seem to do much for me. Artificial Tears (or just good old saline eye drops) do the trick, but then I'm pretty iffy about putting stuff in my eyes. What I do now is just set a timer for 15 minutes, and whenever that goes off, start blinking like crazy. I read it somewhere, but apparently it's blinking that lubricates your eyes. Staring at anything without blinking dries your eyes out, and those crazy blinking sessions seem to lubricate them enough for me.
