Why is Dora the Explorer blind?

This stem comes from the children's cartoon Dora the Adventurer, which is an English teaching film. It tells the story of Dora, a little girl, and a little monkey taking risks everywhere, and teaching English to children through all kinds of things they encounter during the adventure. Recently, however, some netizens revisited and found that it is difficult for Dora and her friends to see things close at hand, because cartoons will repeat words many times to achieve the purpose of teaching, such as where are the keys, and repeat them four or five times before finding that there are keys nearby. The netizen named Dora Blind Dora. Dora is blind. She always turns a blind eye to what is in front of her. Dora means blind. In fact, this is teasing and pretending to be blind, just because I don't want to watch it. There are many props in the story. Dora always asks where this thing is or something. In fact, it can be seen at a glance, which causes many netizens to be very anxious when watching anime. I don't think this is actually Dora the Explorer, but actually Dora the Blind and Her Guide Monkey. Haha.
