What is eyes sparkle attraction?

The term eyes sparkle attraction generally refers to the phenomenon when a person's eyes appear to be shining with happiness or excitement, which can be particularly attractive to others. This sparkling effect is usually caused by light reflecting off the surface of the eye, usually due to an increase in moisture or an enlargement of the pupil. The attraction factor comes in because people tend to associate the sparkle in someone's eyes with positive emotions like joy and enthusiasm, which can make that person seem more attractive or appealing. However, it's important to note that eye sparkle attraction is just one aspect of overall attractiveness, and should not be solely relied upon as a basis for attraction.
