If we leave aside the many different potential triggers, I was wondering if there are prevailing theories out there for the possible mechanisms or medical causes for these problems? I've seen some people talk about binocular vision issues but haven't seen much else if that's discounted. This seems to me to be at least as important as finding tech that might work for each of us individually but I know it's a minefield trying to isolate health issues on an internet forum. Still, it would be great to hear what ideas there are or indeed compare medical situations to see of there's any commonality.
Personally, I don't have any obvious eye issues as far as I know (having been checked out for eye health recently but only by an optician). I have perfect distance vision having had lasik 12 years ago but now need reading glasses due to normal aging (I'm aged 51). My doctor put me on beta blockers as a migraine prophylactic but I don't think it made much difference and I have since come off them (easier said than done!). My symptoms progress through tightness around the eyes, nausea and headaches that don't respond to over-the-counter analgesics, which can last multiple days. The pain is centered around the eye socket, with tenderness in the muscles responsible for eye movement and around the orbit. I am in good health otherwise, just some mild allergic rhinitis but nothing significant and without migraines from other sources. Triggers are phone, laptop and monitor screens, not TVs or light bulbs - any such screen since around 2016 causes problems, regardless of screen technology.
Be great to hear anybody's thoughts!
