If you're working near florescents, try moving or turning them off. If you made an unlucky draw in the gene pool lottery, the fast flicker from florescents can interfere with your eyes' ability to focus, which can lead to eye strain. Taking a periodic break to stare at something distant is good. My optometrist claims that getting a 15 minute dose of indirect sunlight (looking at something outside with a blue sky background) is even better. An eye exam will also rule out something like cataracts, which usually hit when you're a lot older, but may arrive early if you made a particularly unlucky draw from the gene pool.
