Monitor Strain - Brain fog, neck pain, fear of seizure(?)

Infinite I am on the lower end of testosterone as well.

Got mine checked and it is LOW. Mine is 160 ng/dL, where lab reference normal is 250 ng/dL - 827 ng/dL. I am mid to late 20's and a doctor told me even 250 is too low for my age! Going to see a doctor about other testing and treatment.

Am not sure it is related to our screen issue or not. I know that migraines are much more common in women and they suspect it may be related to hormones (but this is just a theory). This article claims that testosterone might help prevent headaches by "reducing swelling in the brain", "increasing levels of serotonin" and "stopping cortical spreading depression ". And an actual study here.

If I am given treatment, I will report back with my results as it relates to screens.

Anyone else get their testosterone checked? Here in USA, you can get it tested without a Doctor's order by using something like Quest Labs.

ryans Mine is low for a woman.
I also have migraines, but they have zero connection to eyestrain (If there was a connection I would be dead right now )

But for my personal case I strongly believe that something in light damages my eyes: I tested looking on the bad phone next to the mirror, I see little blood vessels immediately appearing, after 2 seconds.
If testosterone makes some impact here, it could only make this damage less painful, but not prevent it.

P.S. In Eastern Europe anything could be checked without any doctors orders; so I went to complete ophthalmological check-up with a lot of tests and my eyes are absolutely, perfectly healthy.
I went there in sunglasses though, cause after the phone I couldn't handle even a moody weather.

xelaos who knows.
I still tend to blame the light, cause muscle activation cannot give me any symptoms of extra light sensitivity (to irrational levels). The ophthalmologist who ran all the tests also do not know the reason; she said she have more patients with similar problems.
I have never had in my life any, even slightest, light sensitivity of any kind.
(just to give a context, I suffer only with modern smartphones)

xelaos yep
Just a subjective feeling that a closed eye better reacts to light afterwards. But everything else, including muscle pain, is present no matter what on both eyes.
I have no bvd based on the string test posted here, and I already wrote that the smartphone breaks my vergence immediately, it is the same with one eye patched. It takes time to "repair" it with exercises.
