Eye spy ......

I have been seeing my optician for about fifteen years. We meet in a dark room about twice a year , my husband knows all about it .
He (the optician) gazes into my eyes, and shines bright lights at me, and asks me lots of questions. I shout my answers back, and he writes something down on a record card.
I haven't got a clue what he looks like, as without my glasses or contacts my world is a blur .
