For example , when eyes are normal direction, left eye 0.46 degree right eye -3.85 degree when eyes are inward direction, left eye 0.19 degree　　-> difference from normal -0.27 iright eye -4.16 degree -> difference from normal -0.31 The right side is positive value. I think , right eye negative, left eye positive, but the result was different.

The results were slightly different. I don't know which one is more accurate than the other.
