In brief

The purpose of this study is to learn more about abnormal body rhythms in blind boys and girls that keep them from falling asleep at bed-time or cause them difficulty staying alert during the day. The investigators hope to learn if there are any differences between the body rhythms of girls and boys. The investigators also want to investigate whether age or puberty have an effect on body rhythms.
