Monocular vision...

[Hitcher]

I don't think monocular vision can be corrected. At least not with glasses etc.

It's often caused by both eyes not working together. People can see quite well through either eye, but generally have a dominant eye that does all the work for them. That's why the one red eye in those family photos. I suspect that by adulthood there is bugger all that can be done by way of exercises that will make both eyes work as a team.

What is the most galling is that she has done the special driving course, passed it with a perfect score and has been driving the big white bus on and off for the last month when working shifts. All without any problems.

Had it all my life both eyes work seperately but in parallel. This gives me double vision, not a problem until you crash a bike and some spectator shines a torch in your face and pronounces brain damage, you explain that you have had it forever, "OH SHIT IT'S SERIOUS". One night or one weekend in hospital because someone with brain damage doesn't know what he is talking about!!!!!FFS.Only now my left eye is down a bit (only read to the 4th line) Nornally i can read to the second to bottom.At the moment I have an Inflamed Corotted artery and one of the symptoms is dould vision bugger I didn't see that one comming. I have great priffial (?) (side vision) and no depth perseption. Regards Richard

\Who has it? And how does it affect your life? Ever been turned down for a job because of it? Can it be treated?

- Me.
- Not much, eyes go skew when I'm tired, and I favour one strongly over the other.
- No.
- I tried surgery as I was also having headaches. Complete waste of time and money, my advice to anyone is the same situation is don't bother.

fail the eye sight test for drivers licence.

Really? When they ask you to read a line with 12 letters on it (you know by the size of the letters) read the left 8 with your left eye, shift focus to the right eye and read the last 4...

This means that she can't see in stereo - or 3D - and therefore has trouble gauging distance, determining the rate of approach of another vehicle. That sort of thing.

There's a third dimension???

Actually, I have pretty good depth perception and can judge speed of moving objects, etc, but am definitely monocular rather than stereoscopic. I reckon it's just "in software", rather than hardware: I choose to look at the same things at the same time because otherwise I scare small children, and at the same time I figure out the things the hardware isn't doing for me, like depth perception etc. Sorta simulated/assisted binocular vision.

Then again, maybe I have no real idea of "proper" 3D so don't know what I'm missing?

APPARENTLY.....virtual reality computer games have shown some promise in improving monocularity I read it on the internet so it must be true!!



I also found out, while searching on the internet, that the specialists have misdiagnosed my "condition" all these years. I don't have a lazy eye.... I have a lazy brain. Who'da thunk it

And for the record .......Autostereograms suck farken arse!!!

Monocular vision ..where both eyes work seperately rather than together.

I have monocular lenses inplants in both eyes, and you know how they twinkle...

Surgery worked for me....kinda. That and farking patches....I wanted to KILL my specialist at the age of 5!!! Improved the wandering eye a little, but when I am tired my left eye still tries to bury itself under my nose.

Yeah, like mine told me, I have brain damage LOL

I read a great article in a bike mag of all places. It was written in the late 80s & went along the lines of a chap who did well at his local MX races where he knew the track but always crashed his brains out in Enduros etc.

he went to this specialist who incidentally had done a lot of testing of top sports people to see the relationship between great eyesight (working together not just vision) in several categories, they tested top tennis players & all sorts. Top scorers in 2 of the tests were Eddie Lawson & Mike Bell.

Anyhoo they gave him a bunch of tests & worked out his dominant eye meant his vision was basically monocular. There was nothing otherwise medically wrong with him. He was given a heap of exercises & though they hurt one day he walked out of the office & realised he was seeing in 3D. He was happy but wished he'd done this years ago when he was young enough to make a break with his racing. He'd done ok at his home track because he learned it & was judging speed by size increase & familiarity. Something he couldn't do elsewhere.

Obviously this wouldn't be the case for everyone, but worth asking your optician if they do anything in this line. My old Optician gave me some exercises, basically covering one eye & focusing back & forward, but there were a bunch more in this article. I try to do this before riding sometimes to try & remind the other eye to join the party.

Hmmmm...interesting. Monocular but have depth perception. You should try the 3D butterfly thing I mentioned earlier.
YT tells me that what she sees for real looks no different to a photo or on TV.
There used to be a kid's toy - a binocular viewer that you put a picture in. If you looked at the picture through both lenses, it appeared to be 'real'...close one eye and it went flat/2D. This was because there was actually two pictures, slightly different to each other. The viewer sort of merged the 2, giving the illusion of depth. I think this is how 3D movies work. There's two pictures playing simultaneously, but you need the 'special glasses' to be able to see the 3D effect.
Sort of the same as our eyes. Each sees a 2D picture from a slightly different angle and the brain interprets the two images as one with depth.
Ever noticed how predatory animals have both eyes facing forward? They need the triangulation to accurately gauge distance. Same as us. I guess an animal that has the monocular problem is going to starve? Or learn to compensate in some other way.

As for gauging distance, I think it would be fair to say that most of us are fairly accurate over a short distance, because the triangle effect is greater? People who lose an eye have to relearn how to judge distance otherwise they'd have all sorts of trouble trying to grab the salt shaker at dinner...people with monocular vision would be the same, may have been clumsy as a child but eventually learned to compensate somehow.

Yes, I have it.

20 / 20 vision separately, but together looks like shit.

I can bowl at cricket bloody well, but can't bat for shit.

Wore glasses for a few years when I was younger, but haven't done for 20 odd years now. No issues with drivers license at all.

I don't get those puzzles you're supposed to 'see through' and 3D movies aren't.

Never knew it was so common until this thread.

As with others above, when tired (or drunk), left eye has a mind of it's own and some people don't like playing poker with me as a result. I'm definitely right eye dominant.

[bikemike]

me
I found out at 18 when I went for flying scholarship tests with RAF

'where does the horizontal line cross the vertical line?'-
er, it doesn't... long pause and some note writing... :-(
They invited me to do photo-recon as my eyesight was good. Not quite the same as throwing a Tornado through the skies though!

I don't find it a problem mostly as I don't play ball sports - though badminton I managed.

I don't like tree lined avenues at speed, the rapid oscillation left to right really messes things up.

I did eye exercises about 12 years ago, Bates method. I actually got a few glimpses of stereo vision, very emotional. But did not persevere, who knows if it would have made any difference long term.

I was told recently that it is a tendency that runs in family. My two boys have signs of it but look to be overcoming it.

FWIW I also thought that the new 3D TVs would be a fail for us Monos, but I saw one the other day and whilst I can't say I saw in 3D, it did look very deep and rich compared to a regular TV. Try it!

At my work, there was a 1 in 10 known incidence of this condition. I don't think it's that uncommon.

Oh, my right was dominant and my left squinted, but at about 30 years, the left became dominant (I guess the right was fading...) and now my squint is less obvious, unless I'm tired.

[ducatilover]

Erm, I think you'll find that astigmatism is a compression of the eyeball that causes lines at certain angles to go out of focus.

This is true.

I have interesting eyes, monocular vision, not so noticeable for me as my left eye is fairly lazy, I have astigmatism also. A score of 6/12 in my last eye test was fun, I have to see (Hah, pun!) a specialist and get a cert to sit my licence tests.
