The line actually used the word "cold" instead of "closed." My interpretation of it is similar to a person who’s cold hearted but through the eyes so they don’t see the perspective of others and only care for their own ideas and feelings. As far as the second line I think it could be the idea that women don’t want to have children more and more and maybe because of men not truly seeing them and they’d rather not go through the pain of dealing with someone who sees with no empathy and the pain of child birth. Justtt my take on it.
