    Hi all.

    I tried to google this but didn't find what I was looking for and of course thought that "surely someone on sciforums knows this, so I don't have to bother with harrassing searchengines"..well..

    I'm redesigning my Pinkeye logo ( I once had a clothinglabel and company named Pinkeye) as a typography assignment, and instead of making the eye above the 'I' symmetrical I considered making it either a eye from the side, a right eye or left eye. So here comes the question:

    Which eye is dominant for the perceiver? Which eye do we prefer to look mostly at when looking at another person? Is the right eye, seen from the beholders perspective, more powerful ( as in catching attention) to look at than the left, or vice versa? There must be some investigation done around this, right? I just can't find it.

    For behavioural and commercial purposes such information must already have been gathered.

    Or is it individual, no norm detected? Or does everybody else aready know this but me?

    I want to know which eye is more powerful for the logo, obviously.

    My left eye is better, even after correction by glasses. Does that mean anything?

    I thought so. Honestly, I don't think you'll get a clear answer to the dominant eye question. There are left- and right-handed people, and very likely the dominant eye changes from person to person as does the dominant hand.

    You can research which brain hemisphere does what tasks and which eye is connected to which hemisphere (I belived the nerves are crossed, but also coupled), to finf out which eye will be more direct input to what function. But even then, you still face the problem that the femal brain is a bit differently organized than the male brain, and therefore the eyes are connected to differently used part of the brain. E.g. the average male brain has almost all speech processing in the right hemisphere, the female brain does it left and right. So even if you find that in males one eye has a "shorter wire" to the speech processor, indicating that it might be the dominant eye for catching headlines and logos, in females, it has not.

    All this says to me, it's fruitless to ask for the dominant eye. Too many aspects come into account, too many to give a clear "left" or "right" for everyone.

    And you still face the millions of people with eye problems, like me, where the "better eye" is just the better working one, regardless of brain and nerves. Actually this is often a problem of the retina and not the lense, so no correction can solve it. One eye probaly has a better retina, and therefore will see sharper, even if all optic problems are corrected to 100%.

    If one were to conduct a scientific experiment on a large enough amount of people to get a plausible indication on which direction it leans toward, one could find an answer.
    The ocular dominance is about which eye we use the most, but what I wanted to know is what eye catches our attention the most.
    Is it automatically then one straight across the beholders dominant eye? If so perhaps it is like right and left-handed, and how many are lefthanded, 10 %?

    What brainresearch are you referring to here? Doesn't sound valid at all. I seriously doubt the differences in male/female brains are that big that they wouldn't react similar when exposed to the same type of graphic illustrations. Individual differences are probably more common than genderbased.

    "In face recognition, a left side bias effect has been consistently reported. For example, a chimeric face made from two left half faces from the viewer’s perspective has been reported to be judged more similar to the original face than one made from two right half faces (Gilbert & Bakan, 1973), especially for highly familiar faces (Brady et al., 2005)."

    My wife has prosopagnosia (face blindness) from a head injury she suffered as a teenager, so facial recognition is something she accomplishes only with great difficulty. Most people who possess normal ability to recognize faces do so preferentially with the left side, particularly the eye and mouth areas.

    Does that help?

    Stroke victims. Males with a certain region in the right hemisphere often lose speech, while females witht he same damage retain speech. This lead to the idea that the female brain processes speech in more but only this one area. This was a purely statistic sort of research, though.

    But I have no sources at hand (and I'm too lazy to serch now), so if you think it's wrong, well, let's settle with that.

    Thank you, that was very helpful. Sorry to hear about your wife though, what other forms of recognition does she use the most ( just curious)? Sound of the voice or names? Smell?

    I think it is the "third eye" which is more powerful than the left or right eye. https://en.wikipedia.org/wiki/Third_eye

    The most recent pop-culture bit on dominant eye came through the local news last week; this is the recommendation:

    • Thumb and forefinger on each hand, make a triangle.

    • Look through the triangle with both eyes, focus on object in middle to long distance.

    • Close one eye. How much does the object move in your perspective?

    • Open the closed eye.

    • Close the other eye. How much does the object move in your perspective?

    • Open the closed eye.

    • Release triangle in your hands, do whatever you want with them.

    ↳ By which eye did the object move less in your perspective? This is your dominant eye.​

    The actual science, naturally, isn't explained in local news reports. But it's a pretty reliable result, and makes for a few fun minutes in which everyone in the room is peering through triangles and closing one eye at a time.

    People who take selfies more often photograph their left sides - regardless of whether they are left or right handed, studies show.

    Not sure what the implications would be for marketing.

    Yes, the eye in the logo is of course the third eye, but with more basic perceptual mechanics involed its impact can be improved, or do you think the symmetrical symbolic eye is to prefer in that aspect?

    Have to reschedule this exercise for tomorrow, right now it's both eyes closed..if only the wine effect would diminish so I can ditch the up and coming hangover ..I accidentally slurped down a whole bottle when I was supposed to stick to a half.
    But, the triangle is also a part of the logo.

    I think all the three eyes can be incorporated in your logo design.

    Hair style (and even doesn't recognize her youngest son at the airport when he lost his ponytail!). Instead of recognizing mouth and eyes like most people who are not face blind, she makes use of clothing, shoes, everything but features faces. Interestingly, in my wife's case, the color of skin doesn't enter the equation.

    The way I see it, in her line of work (a Speech-Language Pathologist), this is actually an advantage.

    Yes they can, but should they?

    I think they should because all the three eyes together represent our complete vision mechanism. With the two visible eyes we can see all the visible things. With the invisible third eye we can see the invisible things like intuition/insight etc. Third eye is also the sixth chakra in the chakra system of psychic energy centres in our subtle body. https://en.wikipedia.org/wiki/Ajna .
