Well I would have said ‘bloodpressure’ too, but actually I’m not so sure.
I know that glaucoma (increased pressure within the eyeball itself) may cause vision problems, as well as longterm damage, by partly occluding the micro vasculature of the retina, leading to tissue death.
However glaucoma is mostly caused by blockage in the drainage canal that leads from the eye.
If the pressure in the eye increases (and it’s not fed directly by the blood, so a rise in BP shouldn’t directly affect it - after all, there are shitloads of folks with high bp but normal vision) then it may slightly distort or displace the lens. Your manual pressure, by pulling the lid, etc, is enough to force the lens back into position, I guess, relieving the syptoms. Much like squinting assists the function of the small muscle that controls focus of the lens.
I suggest that anyone with vision problems, visit an optometrist (or optician, I suppose) and have them look in the eye to check for blurring of the fundus and/or other abnormalities - especially those on longer cycles.
On a side note, I remember reading that there is a steroid that almost exclusively binds to the little muscle that controls lens thickening in the eye for near vision.
This muscle atrophies with age, hence the need for reading glasses in some more mature individuals.
So, this steroid should allow the muscle to hypertrophy back to it’s original size, and be able to once again focus the lens properly, negating the need for glasses.
Off track, sorry.
That’s ok, it seems what you’re saying is that there is in fact anecdotal evidence that steroids exist that do effect vision…which is something.
I’m leaning toward the pressure theory since my face is a little bloated and I can see perfectly by seemingly relieving that pressure.
RJ - good to know It’s not just me.
