22M, eye pain (and headache) with eye movement

Hi all,

Usually its fine in the morning, but as the day progresses my eyes start feeling tired and I have this pain in the back of my eyes when I look extreme up/down or sideways. This pain kind of travels to my head which gives me a mild headache in a few seconds. No other symptoms. Ophtalmologist says it’s a case of dry eye strain and prescribed moisturizing drops but it’s been 3 weeks since the symptoms first came.

I’m wondering it’s mild ON. I have no other visible symptoms and there’s been no deterioration in my vision(I wear glasses). Should I specifically ask my doc to look for signs of ON?

PS- I have a high screen time (~8 hours) and had a similar episode before, but my eye recovered in a day or two. Non-smoker.
