Is your vision blurry after using a viewfinder for awhile?

I have perfect vision so far as I know, but when I use a a viewfinder for more than 20ish seconds I have trouble focusing my eyes properly for a bit afterwards. My eyes just don't seem to be communicating with each other properly and it's as though I just woke up in the morning, it's a bit disorienting. It usually lasts about 20 minutes.

Is this a known thing that happens to other people?
 
Not here.
 
Not just 'good enough'. Your eye may be under strain.

If you're finding you need to swing the adjustment to the extreme and it's still not perfect, maybe it is time for that eye test.
 
Most viewfinders have an adjustable viewfinder focus to accommodate people with glasses (so they can look through the VF without glasses on). The similar setting on binoculars was called "diopter" but has been adopted by camera manufacturers because it works the same way, and "henopter" just sounds too funny. "Camera diopter" will get you excellent hits in your search engine of choice.

It is possible that you inadvertently adjusted it, I do that all the time as I stow it in a bag. If it is adjusted incorrectly it can have the effect you describe. Look for a tiny knob/dial near the base of the viewfinder, near the body.
 
Starting with blood pressure ? Then inner ear ?
See the optometrist afterwards.
 
I was prepared for the OP to say the effect lasted for 20 seconds, and I was ready to suggest eyestrain (and a diopter correction) or dry eyes (and some eyedrops-- this is a problem I have).

But 20 minutes may mean something fairly serious. I'd head to the eye doctor right away.

No problems with me but perhaps it is related to your EVF... anyway I recommend you look for a doctor.

Regards,
 
Try keeping both eyes open and make sure you do use the dominant eye with your VF.

A simple test to determine your dominant eye is to extend your arm and have your index finger over a small object in the distance (having both eyes open)

Now close one eye at a time, the finger will be closer to the object when you look through the dominant eye.

Mind you, this is assuming that it isn't your camera or VF setting that is faulty or incorrectly set.

Yes, same thing happens to me, but it generally goes away after a minute. I also get a headache if shooting for more than an hour with an EVF or OVF. I think it has to do with scrunching up the muscles to close my non-shooting eye.

I really prefer LCD framing for these reasons, but unfortunately mirrorless cameras don't cut it for me, for many other reasons. My Canon 70D is a good compromise.

EVFs can cause pretty severe eyestrain. If I am doing something where I will have to have eye to viewfinder for extended periods, I am not using my mirrorless camera, I am using my SLR.

You shouldn't do that. Keep both eyes open and learn the knack of ignoring one.

Those who use single-eyepiece microscopes have to acquire the same skill.

How old are you ?

Focussing gets slower as you age.

Quite correct.. I have a similar problem and an optician pointed out that as the eye ages, it takes longer to accommodate, i.e. adjust to different distances.

Apart from using a VF, I find a similar effect generally ,especially when browsing in a supermarket with a variety of distances to cover.

I began to notice this when aged about 65yrs. and it has become worse in my seventies.
 
Regardless of age. The OP has more than just age going on here.
 
go get your eyes tested

see a doctor

buy a Fuji X-T1

PROBLEM SOLVED LOL😄

Why would I want a downgrade (unless for a couple of the primes)?
