Don't worry. I have asked the doctor the similar question when my bb was 4 month's old. The doctor used a torch shining towards BB's eyes and told me that since the lights reflected from BB's eyes were on the same direction, they definitely were on the right focus. Hence, she firmly says that BB has no 鬥雞 . She said when BB's nose bone becomes higher, more 眼白 will show up and BB would not look like 鬥雞 anymore. I think your BB'case is similar. You may ask your doctor or the doctor at 健康院 next time.
