As you experience happiness, sadness, anger, excitement, and fear, your body releases oxytocin, a hormone that causes your pupils to change in size. As a result, the pigments in your iris spread apart or compress, giving your eye color a different shade.
Angry eyes are perceived as cold and sharp. They often look as if they're snapping or sparking as they glower, stare, or glare at others. Happiness, on the other hand, can result in eyes that are bright; they sparkle and "laugh" and can even tear up in extremely happy circumstances.
Certain emotions can also change the pupil size, such as anger, grief or happiness. This can cause the pigments in the iris compress or spread apart, slightly changing the appearance of your eye color. Also because the pupil is black, your eyes appear darker.
You might have heard it said that eye colors change with mood, but the truth behind that is the iris is responding to emotional and hormonal changes. This can cause eyes to seem lighter or darker in color as a response to an emotional situation, but this would not be a full change in the color of the eyes.
The pupil can change size with certain emotions, thus changing the iris color dispersion and the eye color. You've probably heard people say your eyes change color when you're angry, and that probably is true. Your eyes can also change color with age. They usually darken somewhat.
At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
The Death Stare
If you've ever angered a narcissist, this is one you won't forget. Their eyes go from their natural colour into something so dark, so devoid of any human emotion, you become paralysed.
Findings from a second study showed that the eyes provide equally strong emotional signals when they're embedded in the context of a whole face, even when the features in the lower face don't indicate the same expression as the eyes do.
Studies have shown that when you look at an object or person you love, your pupil size increases. Fear or Surprise Fear is usually indicated by wide-open eyes not accompanied with a smile but often an “O” shaped mouth. Surprise on the other hand is also usually shown by wide-open eyes along with a fleeting look.
The dilated pupils make the eyes seem black. They indicate that the person's brain perceives a threat and is preparing to respond with aggression. You don't want to be the object of possible aggression.
This phenomenon is called eye color associated mood shift. The reason behind it is not clear, but it has been suggested that changes in the eye color are due to a change in the size of the retina, which results in a change in the reflection of light. This effect is considered temporary.
The genetic switch is located in the gene adjacent to OCA2 and rather than completely turning off the gene, the switch limits its action, which reduces the production of melanin in the iris. In effect, the turned-down switch diluted brown eyes to blue.
You can still get a sense of emotions by focusing on the eyes. With happiness, the corners of the eyes crinkle. With sadness, the eyes look heavy, droopy. With anger, the eyebrows straighten and the eyes tend to glare.
Key points. The eyes express all the emotions and states of mind and body. Eyes soften in love, harden with anger, widen in fear, narrow in suspicion, roll in exasperation, glaze with boredom, and weep in sadness.
We dilate when we're attracted.
The bigger the pupil size, the greater the interest. You may notice someone's pupils growing when you stare at them. This is a good sign!
Facial expressions are deeply tied to empathy, which plays an important role during social communication. The eye region is effective at conveying facial expressions, especially fear and sadness emotions.
Mania (manic episode) is a psychological state characterized by extreme mood, behavioral, and energy changes.

The narcissist stares to gain dominance over you. The stare is meant to make you feel uncomfortable and make you feel as if you are in danger or doing something wrong. The narcissist never wants you to feel comfortable in your life because it will make you much harder to control and manipulate.
Narcissists tend to display exaggerated body language and facial expressions. The 1990 study on conversational narcissism also found that narcissists tend to be overly dramatic in their hand gestures and facial expressions. They may also speak in a loud tone of voice.
In particular, eyebrow thickness and a high density of hair were most likely to be used as an accurate judge of narcissism. They expanded on this by measuring how much perceptions of narcissism changed when swapping narcissists' and non-narcissists' eyebrows between faces.
