Genesis 3:6,7 - Then the eyes of both were opened

3:6

As noted in my comments on Gen 2:9, the fact that the fruit was “pleasing to the eye” was not the problem. The problem was the disobedience to God's command. In Romans 8 Paul talks at length about living by the flesh and living by the Spirit. Living by the flesh, the mind set on the flesh, is death. The mind set on the spirit leads to life. So the woman saw that the fruit was good for food, a delight to the eyes and desirable for gaining wisdom, so she ate some of it. She was living by the flesh. There had been a clear command from God and if she had obeyed that there would have been no problem. All our problems stem ultimately from our failure to obey God. She also gave some to her husband, and he ate it too.

3:7

When we sin it changes us, you can never be the same again. Now we all sin from day to day in what we might call relatively minor ways and we don’t notice anything much. But if a person commits a “big sin” they will notice a fairly immediate change and there will be no going back. Before the sin the man and the woman were innocent, but now they had experienced sin, they knew what sin was. Now everything looked different. They realised they were naked. They had always been naked, but before it had never been a problem. Now it was because of the loss of innocence.
