Here's a question I have procrastinated over.

I am right eye dominant and I perceive that the glyphs I am drawing look balanced with normal vision (obviously), or just my right eye. When I close my (dominant) right eye and look with my left eye my glyphs look skewed.

Does this mean that a right eye dominant audience perceive the glyphs in the same way as me, but the left eye dominant audience does not?

I just looked at a few other typefaces this way, I perceived them the same way, right eye balanced, left eye skewed.

Try it yourself and post your observations/thoughts.

(I guess this is a theoretical anxiety, after all, there's not much anyone can do to reconcile it!)

This is probably the most interesting question I’ve seen on Typophile. Hopefully someone has an answer!

Thanks, any thoughts yourself James?

What exactly do you mean by skewed?

I'm strongly left-eye dominant, but when I use my right eye, the letters are not skewed, merely blurrier (yes, with my glasses).

Do you move the letter so it's in the same position relative to your left eye that it was when you were seeing it with your right?

No, I didn't move the letter. That's an interesting idea – to ensure that I am seeing the letter from the same angle. Sounds hard to compensate for/calculate but it could very well explain what I am seeing.

By skewed I meant it looks less harmonious, for example an overhang appears to project more or the tension of the shape changes. Take a letter like 's' for example. I perceive it first as upright, then leaning forwards.

I looked again today with less tired eyes but the effect is still the same.
Now I am worried about my vision.

Go get your eyes tested.

Does this mean that a right eye dominant audience perceive the glyphs in the same way as me, but the left eye dominant audience does not?

I don't think so. I think the phenomenon you are experiencing is unique to you and peeple with the same or similar eyesite conditions as yours.

I guess this is a theoretical anxiety, after all, there’s not much anyone can do to reconcile it!

Wanna put money on that? I have had many eye tests in the last two years to find out more and more about the impairment to my eyesite caused by the cerebral aneurysm I had in January 2007. I think you would be very surprized by what opthalmologists can tell you about your eyesite and the things they can do to correct numerous types of distortion and malfunction.

What I don't get is what you mean by "right eye dominant". Dominant in what way? Sharpness, luminance, focal length, or what?

Eye dominance

Thanks for the link Craig. It's interesting that the article reckons approximately two thirds of "the population" (human population?) is right-eye dominant. I think what 1985 experiences is ". . .unique to you [1985] and peeple with the same or similar eyesite conditions as yours." because I don't experience dominance of one eye compared to the other, and neither do any other peeple I know. So, this is the first time I've come accross occular dominance, so I guess the two thirds of the population said to be right eye dominant are mostly mild cases.

. . .a question I have procrastinated over.

procrastinated > pondered?

I never knew about it until my son's pediatrician checked him. He handed him a piece of paper with a small hole in it and asked him to look through it. He looked through it with his left eye. I would naturally hold it to my right eye.

My son has mixed dominance. He throws with his right hand and kicks with his right foot, but very definitely prefers to sight through his left eye. Makes shooting a free throw the correct way difficult, as the ball will normally hide the left eye if you are right handed.

James, pondered over question, procrastinated about posting!

I had wrongly assumed that people were either right or left dominant, I had not heard of mixed dominance.

I think I will be taking another trip to the opticians, my left eye is lazy and I want answers!
I may be attributing problems to dominance when they are in fact caused by something else.

Thanks for all responses, interested in hearing more.

>>> my left eye is lazy and I want answers!

Join the other two thirds of the world!

If the image is skewing, then it may not be strictly an issue of dominance, but rather one of astigmatism in your non-dominant eye.

That is what I am beginning to think kentlew!

Astigmatism isn't really a big deal; it is readily corrected with prescription lenses. (I know, I have it.)

That's good to know, thanks to everyone who posted.

This is indeed an interesting topic.
Anything new on it, Andrew?

I have relatively high astigmatism (3.50), and from my years of visits to the ophthalmologist, I believe it gets harder to correct accurately once you pass 3.0 diopters. I've resigned myself to living with some level of distortion.

sounds like a defect on your left eye 1985, not a plus or minus but cylindrical defect,

"Astigmatism (cylindrical defect): When some-one has a cylindrical defect, the eye is not spherical. Mostly this appears on the cornea, but it can also be somewhere else. Because of this, the light is not broken in one direction, and because of that the sight will be distorted. Often this occurs combined with long- or short sightedness. It is possible to put this right by using cylindrical glasses, lenses or a laser treatment."

It’s not the eye that sees, but the brain. Images passed on by both eyes are processed into a representation and that is where it becomes muddy: the brain makes decisions about what we want to see and what not. Eg if you are focused on things being level, your perception gets tuned to that (the famous carpenters’ eye).

Most important is the fact that most people use two eyes and the brain mixes inputs. When you use just one eye it takes some time for the brain to adapt.

Example: a few years ago I had my eyes lasered. The right one has perfect vision now, which means it is perfectly suited for seeing far off. My left eye has been corrected to about minus 2.5 and is well suited for distances from 60 cms to about 120 cms (I can use my computer without needing glasses — reading is a different matter). My brain picks what it needs — learning that took just a few weeks.
Anecdote: My eye doctor told me that elderly people who have their vision restored (removing cataracts and such) sometimes can not adapt and remain virtually blind. Or fall over all the time.

This might very well be moot, but:
The retina is actually physically part of the brain!
It just extends all the way into the eye cavity.

Not moot, maybe veering off-topic, but wow this is a great piece of knowledge!
(Wikipedia says not part of the brain proper, but of the CNS? Just to be nitpicky.)

Thanks to all who reawakened this thread, interesting to read. I have no updates but will be sure to post when I do owing to the interest.
Anyone know of any decent opticians in London (UK)?
