You are totally right everyone have one eye bigger than the other. One of the most famous celebrities once said: you can never find two things are totally the same in the world. Not only are your two eyes different, but also one of your hand or feet is bigger than the other. Although you may see two eyes are the same, in fact, there are always differences between your two eyes. One eye is bigger than the other. The size of our eyes has a close relationship with the orbital bone, soft tissue and the eyelid. However, even in the same person, the orbital bone, soft tissue and the eyelid are totally the same, all those are decided by your DNA. In one word, everyone has one eye bigger than the other.
