Eyes hurting !!!?!

Eyes hurting !!!?

I keep getting strain in my eyes really bad!!

It comes on for between 15mins - 2 hours and feels like they are popping out (haha) and they also feel very sore and dry when i wake up?

It's so uncomfortable i just feel like i need to close them and i almost feel sleepy? (but it's not tiredness)

I work on a computer but had this even before i started this job.

i sometimes get a headache after it too.

what could this be?

PS I am short sighted and wear glasses.

Thanks :-)

I was going to tell you that it might be because of the excessive use of your computer since I feel that too when I spend hours in front of the computer, but then you said that you've had this before you got your job. So I think the best thing for you would be to visit an optician. Most likely it's not going to be something big and he'll treat it for you. Maybe you just need to change your glasses or learn some eye exercise.
And visit your optician quick, those are you eyes, your jewels - don't jeopardize their health!
