2. WHEN YOU KISS WITH THE EYES OPEN, IT TAKES THE ROMANCE AWAY FROM THE MOMENT
Kissing is meant to be a very romantic exercise where both parties are lost in the moment, but that can only happen if both of them shut their eyes while at it. It would be so weird and empty for one to kiss with their eyeballs staring at each other.
3. IT’S UNHEALTHY FOR THE EYES TO NOT DO SO
The eyes are not designed to look at objects from such a close range (distance), staring at your partner’s eyes while you kiss them can expose your eye sight to danger.
