Pinhole Glasses are now a daily activity for Rookie. They have tiny holes all over the black lens. The purpose of them is to force central vision and cut out all peripherals. He only has to wear them 15 minutes twice a day so I typically choose to have him wear them in the morning during our signing time video and in the afternoon after nap. He does pretty well with them now, but I do have to keep an eye on him. Sometimes he likes to peek over the top.
