- Pupil dilation is the pupil's response to light. The pupil is a shrinkable hole in the eye's iris. The pupil itself adjusts its size according to the intensity of the external light. The pupil with a strong light becomes smaller, and the pupil becomes larger with a weak light. This is self-protection for the eyes.
- The pupil not only responds to light and darkness, regulates the light entering the eye, but also affects the optical system of the eyeball.
- The doctor regards the pupil as a sensitive indicator of vital function. Everyone knows that when the light is strong, the pupils will automatically shrink, and when the light is dark, the pupils will expand-this is called the pupil's response to light. If the pupil's slow response to light or disappears, it means that death is imminent. In a comatose patient, as the loss of consciousness increases, the pupils will gradually dilate, and full dilation is the sign of the end of life.
- When a man meets a woman he likes, his pupils dilate, and conversely, when he meets a woman who is sick of him, his pupils shrink. This is the charm of the first impression of "beautiful beauty in the eyes of a lover."
- The delicious food presented in front of your eyes will also make your pupils larger, and hungry people will become bigger; when you listen to beautiful music or taste delicious drinks with your tongue, your pupils will also enlarge. In addition, the pupils dilate in the state of horror, tension, anger, affection, pain, etc., and they shrink in the case of aversion, tiredness, and trouble.
- What's more interesting is that the change in pupil size will reflect some mental activities. When there is a strong interest or pursuit of motivation, the pupil will quickly expand. The ancient Persian jewellery merchants sold jewellery based on the size of their pupils. If the sparkle of a diamond ring can dilate the buyer's pupils, the merchant will pay a higher price.
