i get headaches everyday for a year, im looking for a good solution for this problem

let me tell the chronology

june 2007 - sept 2007, at first i didnt have any headaches
but i got some kind of eye strain, a painful one
my eyes turned red, with slight headaches happened for almost 3 months
tried to go to optiometrist, bought new spectacles with new lenses, i even changed it 3 times, however the result is still the same, but surprisingly, when i put off my glasses, it cause less pain

sept 2007 - now, this is when the headaches came out
my eyestrain problem became softer, not as painful as before
i tried to go to many doctors, neuro doctors, eye doctors, optiometrist, eye nose throat doctors,i even tried herbal medicines and acupunctures
i tried to do CTScan, but the result were ,my head looks normal nothing wrong

the headache is located at almost every place in my head
but mostly, at the back, and almost every point where my spactacles directly contact with my head (near ears etc
that is why i primarily suspect spectacles and/or my eyes as the source of my headaches
however, even i put off my glasses right now,
the headaches will still be the same
i still dont know what to do,

ps: i used to like to play in front of the computer

can anyone tell me what kind of headaches this is? or who should i go to?
