As some people said, the right and left sides of our body are different, including eyes. Some features might subtle, while others are striking. Orbital dystopia can also cause eye asymmetry. Some doctor can perform an ultrashort incision cheeklift, not surgery but a physical therapy, to correct the situation. If the uneven situation is not quite obviously, do not worry. Ok, everybody's right and left side of face are not the same. Lift your lower eye 100times every morning and night. Make point massage around eyes.If your eyes are uneven seriously, you should consult your doctor ASAP.
