here let me give you some tips
I had the same thing before, a headache above the eye.
You need to take 20 20 breaks like every 20 minutes look at something 20 feet away
It's preventive though if you do it now it's worthless
The only thing you can do is lay down, close your eyes, try to nap
it gets better after you nap or sleep
If you keep looking at a screen it gets worse
but it's still gonna get worse if you don't lay down and sleep
