I feel like eyes are like windows – you can tell a lot about a person from their eyes. How interested they are in something, how they’re feeling emotionally, things like that. That isn’t entirely related to this photo though – what is related is that when you put glasses over eyes those eyes instantly look smarter. Really, it’s a fact of life.
I chose to crop this photo to only show the left eye because we’re always taught that the brain is split into two halves – the left and the right – and that the left half is more intellectual.
