what kind of glasses do we wear?

"Wouldn't you hate to wear glasses?" one small boy asked another.
"No, " said the other, "not if I could have the kind my grandma wears. My mother says she can always see when folks are tired or discouraged or sad. She sees when somebody is in need, and she can always recognize when you have something on your mind that you need to talk over. But best of all she can always see something good in everybody."

Those are called glasses of grace and we all need them.
