Essentially, the brain &#8220;prefers&#8221; one eye over the other. Of course, this is something that <em>ordinarily<\/em> goes unnoticed, but it becomes quite important in some things, including, apparently, firing a weapon. There are two easy tests to determine your &#8220;eyedness,&#8221; as Wikipedia strangely lists as an accepted name:<\/p>\n<ul>\n    <li>Focus on a distant (6-10 feet is plenty) object. Hold both arms out in front of you, overlapping, and form a golf-ball-sized circle between your thumbs, viewing the image through it. And then, do one of the following:\n<ul>\n    <li>Slowly pull your hands towards your face, keeping the image centered in the hole. Eventually, your hands end up in front of one eye. That&#8217;s your dominant eye.<\/li>\n    <li>Rather than pulling your hands back towards you and looking ridiculous, close one at a time. With one eye, you won&#8217;t be able to see the object: your hand covers it. (If you can see it through both, the hole through which you&#8217;re viewing it is way too big.) The eye you <em>can<\/em> see the object through is your dominant eye.<\/li>\n<\/ul>\n<\/li>\n    <li>Or, with both eyes open and without paying too much attention, point at a distant object. (Don&#8217;t look at your finger or you&#8217;ll screw things up and have to start over.) Hold your arm steady and close one eye at a time. One finger will be pointing (more or less) right at the thing. The other is pretty far off. The one that&#8217;s accurate is your dominant eye.<\/li>\n<\/ul>\n<p>Of course, I&#8217;m left wondering a few things:<\/p>\n<ul>\n    <li>Can you accurately use your non-dominant eye? With one eye closed, if you can align the sights of a gun with your target, isn&#8217;t it still going to be accurate? I&#8217;m trying to &#8216;test&#8217; this, but doing it with a flashlight isn&#8217;t accurate enough, and I don&#8217;t have a laser pointer. Further, I feel like a total goofball sitting here squinting with one eye and shining a flashlight at the electrical socket on the other side of the room. To align the flashlight and flashlight, I do shift the flashlight a little, but in both cases, it&#8217;s being pointed in the same place; it&#8217;s just a question of the angle.<\/li>\n    <li>Can you change your dominant eye through practice or the like?<\/li>\n    <li>What are the implications in daily life of having your dominant eye be your weaker eye? Uncorrected, I&#8217;m something like 20\/300 in that eye. Would my perception of scenes be better if my dominant eye was the one with better vision?<\/li>\n    <li>The Wikipedia page makes a cursory mention of the two eyes and how they&#8217;re processed by the two brain hemispheres. Does this related to being right-brained or left-brained? Is this like the spinning girl and seeing whether she spins right or left?<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>I mentioned in my previous post in passing about determining which was my &#8220;dominant eye,&#8221; something I&#8217;ve merrily gone 22 years without knowing I had.
