Final Of Anime Closed Eyes Trope Collection 2020. Eyes are big and round, every color is allowed for eyes and hair (not to mention hairstyle), etc. Milky white eyes make it impossible to tell which way an actor is looking and makes the effect of a blind, fixed stare more convincing.
Leo from jungle taitei (kimba the white lion), jungle taitei (1989), and jungle taitei: Usually done with a smile though. Its not realistic at all.
Its simply put as “eyes shut in” trope.
Yuuki ga mirai wo kaeru (jungle emperor leo). Back them up with references or personal experience. In my opinion, there's not just one specific reason/purpose why some anime characters have closed eyes. So much anime trope garbage doesn’t make sense when examined closely or put into the real world.
