|'m not sure if this is related but I have poor vision in one eye (-3) and
average vision in the other (-2). I often wear contacts but when not wearing
them I try to avoid wearing glasses except for driving, tv etc. As a result I
often get strain in the poor eye - is this as a result of not seeing properly?
I also notice in photos that this eye appears to turn in.

Are these two things in any way related, I mean the eye strain and the eye
turning in?

  Yup, very related.

There's no reason to avoid wearing glasses.

Not wearing your glasses is a common reason for discomfort.

> I also notice in photos that this eye appears to turn in.

It probably doesn't, in the conventional sense.

It might if you weren't wearing correction during the photo. Your -3 eye
could be too blurry for the fusion reflex to work. That would be pretty
normal, not true esotropia.

Otherwise, when nearsighted people's eyes "turn in" it's usually constant,
present since birth, and they seldom develop stereo vision without surgery
and orthoptics. So if you can see 3-D illusions, it's unlikely you have
anything to worry about.

People who DO suddenly develop esotropia complain about double vision. They
complain a lot.

Sounds like you're getting more strain from *not* wearing glasses than if
you just left them on.

Which urban legend told you not to wear glasses?

Thanks.  Can you tell me what it is that causes eyestrain/discomfort? My
optician tells me shortsighted people don't suffer from it.

Actually I was wearing my contacts so that's not the reason, but I never have
been able to see those 3D illusions.

No double vision, thankfully.

No-one. I've always worn them for tv/driving etc then taken them off whenever
I finish doing something that's visually demanding. Is that unusual?
I told the optician about the discomfort and he couldn't find a reason which
led me to think about the eye turning in ...

There's no single, universal cause. Generally it's from trying to focus or
fuse at or beyond the individual's physiological capability. But what
bothers you might not bother someone else.

In general that's true, but it's best not to be dogmatic. Discomfort is
discomfort.

Some people can't make the random-dot illusions work, even with normal
stereo vision. There are other tests, and your optician should certainly be
able to tell if you have esotropia or reduced stereo vision.

Not with an indoor lifestyle.

Photos are pretty unreliable. Even face-to-face, good practitioners don't
rely on appearance because there are some pretty convincing "pseudotropes"
whose eyelids (epicanthal folds) create the illusion of esotropia.

Thanks so much for your considerate replies to my questions. If you're a
practicing optician (or similar), then your patients are very lucky indeed.

In other words.....

Sorry.  Rishi Giovanni Gatti (Zetsu), Lena102938, and Otis Brown are
trolls who haunt s.m.v.

Rishi has published, and is trying to sell worthless books.

Otis is pathologically dishonest and actually hurts people.
Following his advice can induce double vision in those
not working closely with an eye doctor.

Lena102938 uses anti-eye doctor rhetoric as a substitute for ANY
actual information.  It seems she now has to wear glasses and has
developed a pathological (and ILLOGICAL) resentment toward the
industry that "foisted these glasses upon her."

You'd do well to ignore them and wait for responses from the
caring, compassionate eye doctors who DO also participate in this site.
