Everyone has a dominant eye and not by choice. Nor is one able to train the other eye to be dominant.
Put your index finger up at arms length and, with both eyes open, sight down your finger and obscure something in the distance that appears to be about as wide as your finger. When you close your dominant eye, the object will come into full view and your finger will appear to have shifted away from the sight line. When you close your non-dominant eye, the object in the distance will appear mostly obscured and your finger will appear to be in the sight line.

I think I know too much about how my eyes work. That doesn’t work for me as
I see two of the target object. I know my left is the dominant one, but I
have worked a lot with both of them.
I’ve learned to look at stereo pictures that don’t use glasses, which took a
lot of practice to figure out. Then when they came out with thoses 3-D
“hidden” object pictures, I could eventually see those as well. I can hold
one eye still while moving the other one side to side, which leads to lots
of kooky/stupid eye tricks.
I’m the only on in my family that didn’t wear glasses. Both my brother and
sister had them at young ages. But my good eyesight is finally failing in
the near distances; I have trouble focusing on anything closer than 8" or
so. I hope this is not a result of looking at computer monitors at a fixed
distance too much…
No. My wife still has 20/20 as does my daughter who is 25. My son (21) and I both have 20/15 vision. However, I can’t see squat unless it’s over 36" away now. What you are describing is the encroachment of antiquity. That 8" will slowly drift away from you as the eye muscles stiffen and refuse to close focus for you. I have to use reading glasses to read a computer screen now. I like stuff that’s in big print.
Get this:
I’m right __ (fill in the blank) dominant,
I’m goofy footed,
and do most everything like throw and kick with my right foot
BUT I mount my uni with the left foot in back and hop with right foot in front.
I guess I’m kind of messed up, but i noticed something cool the other day. With only my left contact lens in, I can’t really see with my right eye. (i’m not blind but everything is blurry) the wierd thing is that my brain automatically switches eye dominance from right to left when I’ve only got my left contact in because when I hold my arms out in front of me and mak a triangle, whatever object I’m looking at is only centered with my left eye. (???)
My close-focus limit is drifting away (now for comfort at some 12"),
and my far-focus limit is nearing me at the same time. Oh well, the
good news is that I’m not predominantly short-sighted or far-sighted When I was little I could focus unusually close, like 2 inches or
so if I strained it. (Harper, it’s not stiffness in your eye muscles
but reduced “springiness” in your lens that reduces close-focus
capability.)
I can still do a couple of weird things with my eyes, including
unaided stereo photo (only small ones) and “magic eye” viewing, and
rolling my eyes one clockwise while the other goes counterclockwise.
After John’s post I discovered that I can hold one eye still while the
other goes to the inside and back, but not to the outside and only
very slowly. But you should hear my funny sounds repertoire!

Nor do I, but I noticed that if I read for some time, I have more
trouble with far focus as compared to when I have been out in the open
(looking farther away). This is a temporary effect but a tiny little
bit of it may be remnant.

I hate to continue an off topic thread, but it’s one that interests
me…sooo,
Vision measurements on the 20 scale (20/20, 20/15, 20/300, etc.) are only
for distance vision. Close up vision is not measured on the 20 scale.
What the numbers mean are how far a person with normal vision would have to
stand to see what you see. So, 20/50 means when you’re standing at 20
feet, you can make out as many letters as someone with normal vision
standing 50 feet away. (I say normal because that’s where the numbers came
from. There’s no such thing as “perfect vision,” although, at present, the
theoretical limit of optical resolution of the retina is around 20/8.)
Yup, once you hit 40 or so, prespyopia sets in. Then, when you enter your
60’s, cateracts will begin to develop (this is a normal thing, everyone
will get them, the only question is when) and your vision will improve as
the shape of the cornea changes slightly, before things start to fog up,
giving you worse vision, until you have to remove those foggy lenses and
replace them with artificial ones – and you get to chose if you want to be
near or farsighted. Isn’t technology cool?

And I’ll bet if your right leg fell off, you’d use your left a lot more
Right Handed, Right footed, Right eye is dominant.
I start my mounts with my left foot (Rollback, static, forward, running, step over, reverse step over) except for my kick up mount which I have my right foot on the pedal to start and kick with my left.
Freemounting a giraffe is left foot on the bottom.
I idle with my left foot down, feels like i have more control from my dominant foot on top.
In running, I always put my right foot back to start.
In hopping on the uni, I’m a bit strange. I hold the seat with my right hand and hop with right foot forward. I learnt to crank/pedal grab and grind this way. My dominant hopping direction is to the left - im hopeless to the right and can get hardly any height.
And while I dont see how prfering manuals or automatics has anything to do with preference for feet, I’m a manual man…uses less fuel and feels like I have more control over the vehicle.
My brother and I are both:
Left-handed (our mum and dad are right-handed)
Right-footed
mount with our right foot back, left foot forward, and hold the seats with our right-hand. I jump better to my left, and he jumps better to his right. Therefore, we both crank grab opposite to each other. We can both jump around the same height (i’m about 5-10cm higher) which is really weird, coz u’d think that one way would be easier than the other depending on whether you were left/right handed, and depending on whether you were right/left footed.
Actually, this is one of the common ways to become nearsighted: doing a lot of close work without reading glasses. I wore glasses for distance (nearsighted) from when I was about 11 or 12 until I was in my thirties, when I had some bio-feedback training to learn to relax the focusing muscle, and now don’t need glasses for distance at 54.
The way it was explained to me was, I had over-excited the focusing muscle (singular) with close work, and it then, as with any muscle, would stay excited. All I know is the bio-feedback worked and it gives me a perfect excu . . . uh, reason to fly kites, travel to pretty scenery, and watch beautiful women (and 99.9999%+ are beautiful in someway). I convinced my wife to try weak reading glasses while she was doing computer work and she said that she had less headaches and her distance vision was better when she looked up from the monitor (instead of being blurred for a few seconds).

My distance vision has improved with age too. I have wondered around age 30 whether I needed glasses for driving, doctor said no after testing. Now at age 50 my distance vision has improved and I’m sure I don’t need them. And this was without biofeedback, meaning that it can be a natural drift in focal length of the eye lens. If I would have done biofeedback for the purpose I would of course credit it for the improvement!
I now have cheap reading glasses but I seldom use them. I think that if you use them regularly, your focusing muscles become lazy. That’s the other side of the coin (the coin being your argument).
>fly kites, travel to pretty
>scenery, and watch beautiful women
The inclusion of beaufitul women in that lists seems to imply that you look at them only from a distance. Is that age-related too? :-))

Reposted directly on the forum. After almost 24 hours my newsgroup post still didn’t show up.
being very clumsy I suppose I have two left hands!
I am right handed but:
fire pistol with left hand (fairly well)
play tennis with left or right hand (changing hands when needed, same applies for backstrokes) though I do not know to serve with left hand.
when I was younger and practising 100meters dash I started with my left foot
when I did high jump I used any foot (the same while jumping fences)
my right foot is dominant with uni (I can’t do anything starting wiht my left foot)
I drive a car with a stick (I used to hate automatic gear until I broke my left achille’s tendon)
No, I enjoy watching at any distance, of course it gets more interesting when you get really close, but that doesn’t help my distance vision. My biggest vision problem is when I’m doing tango or waltz (international style ballroom - body contact), I have to look were we’re going instead of at the woman in my arms.
My stats:
Right-everthing-ed.
Hop with right foot forward using left hand on handle, I have serious trouble going to my left.
Mount with right foot on pedal first, but I can side mount either direction.
Idle, 1-foot, etc. right foot down or … just better with right foot.
Write with right hand. Play tennis with same. Kick with right foot, etc … as I said, right-everthing-ed.
write right
throw right
learned to mount right down
perform 1 foot skills with right on pedal
hop to left with right crank forward(can hop to right but not as well)
hold seat with right hand(or left, again right feels better)
I have no clue what this says about me or does to the list. However i think in unicycling the body part you start with(when learning to ride or a new skill) is the one you will almost always use. That is unless you make a concious effort to switch.
I think it’s discouraging to learn a trick you already know on the other foot. I can freemount keeping the wheel still ( forget what thats called ) left foot on floor, right on pedal. A couple times I stood there and switched feet, and i’m like " how can I do that". I think i’d have to forget I can do it the other way and learn it over again. It’s kinda like that with riding backwards for me, forwards I can just go, but backwards I have to start back at the beginning.
