Intriguing Eye Facts You Probably Didn’t Know
..................................................................................................... Our eyes can say so much about us, literally. You will be surprised for the amount of information our eyes, eye color, even our tears can demonstrate about our biology. Here are some fascinating examples: We Shed Different Tears : Tears aren’t all similar as they appear to be. We release many different kinds of tears in response to different alarms. The usual kind, basal tears, is normally coating our eyes for protection and moisture. There are also emotional tears that we experience when we’re really sad or happy; they contain hormones that help the body shed off chemicals released from excessive emotions. Similarly, other types meet different needs. Eye color and Trustworthiness : Eye color is linked to facial morphology. For example, brown eyed men, compared to blue eyed, are more likely to have broader chins with larger nose and mouth. Tests show that men with such features tend to appear more trustworthy.
