我猜测是这个原因: When Julie was young, she had a "wandering eye," so she wasdiagnosed with strabismus. She went through some treatments, but they didn't work.Also Julie got a book of eye exercises. She thinks that either she outgrew herdisease or that the exercises worked because she doesn't experience a wanderingeye, except for when she is extremely tired. Jules小时候斜视,长大后即使痊愈了在劳累时也还会出现这种情况。所以戴眼镜也是为了矫正吧。
