7 Strange Facts about Your Pupils

The eyes are the windows to the soul capable of opening like a flower into a little universe of emotions and feelings. Have you every stopped to wonder what your eyes could be telling you?

Today on our site, we’d like to invite you to a take an exciting look into the dark, magical and intriguing centers of our eyes known as your pupils.

As you already know, this part of the eye is responsible for regulating the amount of light that enters the eyeball. But aside from this, it hides many more secrets. Discover them with us. We’re sure you’ll find them as interesting as we do.

1. Optography

Optography is a term that’s not well known today. However, in the 19th century this was a commonly heard term. It refers to the discipline that was developed by the physiologist Friedrich Wilhelm Kuhne in 1881. It was used to analyze the pupils of murder victims.

It was thought that the image of the murderer would be photographically impressed into the pupils of the victim. Numerous studies were conducted on the microscopic level to find out if this would be possible.

In fact, the pupils of some of Jack the Ripper’s victims were analyzed, but unfortunately, they were unable to obtain any clear results. Today, optography is grouped with the paranormal sciences.

2. Your pupils and emotions


Strong emotions like joy, enthusiasm and even sexual desire noticeably dilate the pupils. It may seem odd, but to confirm this theory, a now famous experiment was conducted at the University of California in 1977.

The study included 150 people and consisted of giving each subject erotic literature to read. Researchers observed how certain passages dilated the pupils in every subject, effectively showing this curious relationship.

3. Trying to solve a complex problem


When we find ourselves immersed in a problem or situation that requires a high level of mental concentration, our pupils are often dilated. Especially if the task induces stress or anxiety, a state where the emotions are involved on the one hand and mental absorption on the other.

4. Disgust


It’s a natural and instinctive reaction. Human beings feel immediate disgust towards certain things: unpleasant odors, dead or decomposing material and even unpleasant stimuli like violence, for example.

These experiences also have a direct effect on your pupils, causing them to dilate. Have you ever noticed this? The emotional impact is mixed with the natural physiological reaction of disgust and the need to escape.

5. Pain


You probably already guessed this. The autonomic nervous system reacts to the sensation of pain and activates our flight response. One of the first reactions of our body when experiencing pain is to dilate the pupils.

Do you know why this happens? When the flight response is activated, our brains need all the senses functioning at peak performance. Thus, vision needs to be 100% sharp to detect any potential danger in the environment. Interesting, isn’t it?

6. Your pupils and chemicals in the environment


We can’t ignore the fact that our eyes, and consequently our pupils, are really sensitive to chemical agents in the atmosphere. So, for example, if you wake up one day and notice that your pupils are constantly dilated, you should seek medical attention immediately.

In addition to a possible problem in the brain, dilated pupils can also be due to the following:

  • Poisons or other chemical agents to which you’re allergic. An example? Bark from the carob tree.
  • Jet fuel, chloroform and certain drugs like opiates tend to cause this reaction, which as we’ve mentioned, is a sign that you need to see your doctor.

7. Neurological disease


This information is really important. If after taking a blow, you or someone close to you notices that your pupils are dilated, it’s vital that you seek immediate medical attention. You may have internal bleeding or a neurological problem that requires immediate intervention.

Sometimes, dilated pupils are also a sign of a brain tumor or stroke. In this case, it could be permanent; the pupils are constantly dilated and don’t contract despite exposing the eyes to a direct light source.

As you can tell, our pupils are not only a reflection of our emotions, they’re also an indicator of our health, which is worth paying attention to for our own safety.
