Myop's name probably indicates that she is, figuratively, "short-sighted," or myopic. In Alice Walker's short story "The Flowers," Myop does not remain short-sighted but only begins the story that way.
At the start of "The Flowers," Myop is an innocent, carefree child living in a post-Civil War world where many African Americans in the South are sharecroppers. Their jobs were difficult and did not yield much financial gain, and they also still had to deal with the racism of the world around them. It seems that Myop's parents, however, have protected her from this reality. She joyfully prances around the natural world and seems to have an almost idyllic childhood.
However, Myop goes farther than usual one day, and she comes across a decayed corpse. It is implied that the corpse was a man—a sharecropper—who was lynched, as there is a rotting noose at the scene as well. This discovery opens Myop's eyes to the tragedies and the dangers of the world from which she has been thus far protected. The end of the story states that the summer was over, which figuratively means that Myop has grown up as a result of her experience. She is no longer short-sighted and understands something about the world that she did not know at the start of "The Flowers."
