Genesis 3:5

‘You will distinguish things clearly.’ This does not mean that they would see more clearly. It means that they would know the difference between good things and evil things.

v6 Then the woman saw that the fruit was good to eat. She saw that it was lovely to look at. She also thought that it would make her wise. So she took some of the fruit and she ate it. She also gave some of it to her husband and he ate it. v7 Then they distinguished things clearly. They realised that they were naked. So they sewed leaves together and they made clothes for themselves.
