The Eye Pupil – More Than It Seems

Share your love

Why do the eye pupils dilate or contract? Is it only a response to a change in illumination? Not.

It’s common knowledge that the eye pupils dilate and contract according to the light they’re exposed to. This body mechanism helps regulate the amount of light we receive, which allows us to see better in different light conditions.

Perhaps what you didn’t know is that your pupils react to visual stimulations, too – a positive or negative response represented in the eyes. Your pupils, involuntary, can dilate or constrict in their size according to whether or not you like what you see. Let’s see if we can get a deeper look…

Does Eye Pupil Size Matter?

So what does it mean? In general, the bigger the eye pupils the more favorable and excited the response. Your pupils dilate when you see something you like as if you wish “to grasp” more of what you see.

In courtship, for example, it can be a strong signal of affection – prolonged eye contact with dilated pupils is one of the first indicators of attraction. It can be a misleading signal, but more on that later.

Not only dilated pupils show a positive response in someone, but we also find them more appealing to look at. That’s why babies are ‘programmed’ to dilate their eye pupils when looking at adults – they get more affection points.

Toy manufacturers, understanding this, produce toys with really big eyes and pupils to draw the attention of kids, who naturally like them better. This also explains why kids (and adults) really like anime characters with their excessively big eyes.

The opposite is also true, constricted eye pupils show resentment, defiance, and general disliking. We also like them less. It’s really simple if you think about it – if someone seems not to like you, usually you won’t have much incentive to like him or her back.

As part of my job as a juggling instructor, I work with children. I get to see these reactions in eye pupils almost every day – when a child is happy about his success you can see his pupils turn to a sparkling sphere – he looks full of life! On the other hand, some kids, when being reprimanded, meet my gaze and I can see little defiant needles staring at me…

Eye Pupil Size and Attraction

So, when do our pupils grow the most? When we’re sexually aroused of course… According to an experiment done in pupillometry (the study of how pupil size reflects psychological condition) Heterosexual gender’s eye pupils were dilated in response to pictures of semi naked opposite sex. In females, the pupils were affected also by pictures of babies and mothers.

OK, so our pupils dilate when we’re stimulated, but is it also going the other way around?
Are we attracted to dilated pupils?

The researchers Tombs and Silverman found that guys have a straightforward approach to this question – the bigger the eye pupils – the more attractive they found them. For females however, it’s a little more complicated: they prefer either medium or big-sized pupils, and the tendency to choose bigger pupils is associated with the preference for ‘bad boy’ types of guys.

Advertising companies, taking advantage, often enlarge the pupils of the models on the covers of magazines to tempt us to buy them. Sex sells, and part of this sex appeal is dilated pupils.

If you think about it, it may also explain why we like dim lights in romantic places – it artificially dilates your and your date’s pupils and makes you look more attractive. It’s also a great way to make all of your surroundings ‘fade to black’ and concentrate on each other.

How accurate is Eye Pupil Size in indicating interest?

Thinking about these facts may make you wonder, if it’s involuntary and can accurately indicate interest and emotion, does it make the whole ‘does she like me?’ thing too easy?

Ah, but of course, there are some complications:

1. The biggest issue is that pupils first and foremost dilate and contract according to the lighting setting. Don’t take offense if you see your loved ones stare at you with beady eyes on a bright sunny day.

By the way, that’s why I said that this can be misleading in courtship, especially in a ‘romantic’ dimly lit place. Still, keep in mind that we like to gaze at dilated pupils so it’s not all bad.

2. You need to extremely observant to spot these changes occur, not an easy job when trying to focus on the many other aspects of communication. Besides it can be pretty hard to see the pupil size in dark eyes.

Takeaways

I don’t want you leave you with a feeling that it’s too damn hard to use. So let me remind you that while our conscious mind is busy focusing on the conversation itself, we perceive most body language signs subconsciously.

This means that you don’t need to check every moment what is the size of your date’s pupils but rather allow yourself to relax and become perceptive, knowing the signs will bring them to your mind when you see them.

I hope this post also helps to explain some intriguing scenarios from our life. Like why many poker players shade their eyes during the game – to hide the automatic dilation of their pupils when they get good cards.
