　　Question: My eyes and head ache when I work at my computer for a long time. What can I do?
　　VisionIt could just be your eyes. Make sure that you’ve had them checked and that you’re wearing any necessary corrective lenses.
　　Screen Glare The light you read by may be too bright for your computer screen. Try to dim the light, and if you need to, get a desk lamp for other work. Also, if possible, move your computer so you aren’t directly underneath a light fixture.
　　Screen and Head Position
