I get really spotty vision when i look at the computer?

After looking at the computer for awhile i start feeling alittle like i am going to black out i see spots and cant shake them off i close my eyes and they dont go away. I dont feel sick but the spots are usually followed by a headache. does anyone know what might be wrong? im getting a little worried
Answer:
You should take a 5-10 minute break for every hour yo spend in front of the computer.. try using a tinted screen filter on the outside of you monitor to cut down the glare..Do you need glasses? If this continues, see an eye doctor...

Don't watch as long. If it keeps happening go see a doctor.
