I seldom think about that. My father has glasses, thick ones. What I remember is that his eyes were much bigger when he had his glasses on. That may affect how other people see you. Then the frame changes your looks. German people and especially women have a specific taste for frames that doesn't make them look more sympathetic.

It often surprises me when other people are resistant to wearing glasses later in life. I've had them since second grade, they are just a fact of life!
