18: Moonstone

When Cecilia realised that Moonstone couldn't read the eye chart, she smiled and patted Moonstone's knee and said that didn't matter.
"Let's try a chart with shapes."
There were four large shape outlines, a square, a circle, a house and an apple, she ran through them a couple of times.
"Moonstone if we say something you don't understand. Just tell us. We can find ways to explain things. So far you seem incredibly healthy. This will help me find out how good those beautiful eyes of yours are."
