Eye pain likely due to neuro issue. Be!

I have been facing eye pain in my right eye only for a couple of months now. This happens mostly when I watch screen but in low screen light it's less. I had dialation tests multiple times and consulted various eye doctors, they found nothing unusual and all gave eye lubricants drops. But it didn't help with pain. I think this might be related to neurological conditions. In the past I consulted one neurologist who prescribed the following meds: Amitop 10, Napra D 500 and later betacap plus 10. After taking them I did feel some sensation  around the pain area but still the pain didn't go completely. If anyone can guide me and help me cure this issue I will be thankful as Its affecting my day to day life.
