i'm 22F and i'm experiencing the exact same symptoms, literally everything you mentioned about yourself, eyes don't look normal have become more veiny and red ever since I strained my eyes and migraine that never goes away, reading text is hard and always made me sleepy and now I can't read it at all without experiencing irritated eyes..I was diagnosed with astigmatism a few months ago after I started experiencing dry eyes/chronic eye strain from laptop/phone screens, my heart rate also increases at times like as if I'm having a panic attack, at night my symptoms are better…My new glasses are now giving me a headache so I'm not wearing them when I'm looking at the screen, I experienced that I'm better when I'm not using my glasses,
But it only ends up giving me a headache/migraine..apparently my new has prescription has failed me and My old glasses have started giving me severe dry eyes/eyestrain. (old prescription probably gave me eyestrain and slightly change my astigmatism after I strained them hard?)
My eyesight started going when I was 17 or something and I'm near sighted, I experienced ledstrain a few years back but it went away with breaks and a migraine medication (which is no longer available sadly) also a point to note is that I only experienced this when I tried looking at the same screen I had overused, my phone was giving me zero symptoms back then and now it came back strong, now I'm experiencing severe ledstrain, dry eyes etc after binging on my laptop and it hasn't went away for months..it has only gotten better but I still can't look at many screens or even focus on certain activities without feeling dizzy. such as a book reading/drawing or craftwork…
