1) Frame size
2) Interpupillary distance size
3) Degree level.
4) Refractive index
5) Frame material.
6) If there is astigmatism, the closer the axial position is to 180, the thinner it will be. For people with high astigmatism, the axial position of 180 will have little effect on the thickness. But people with 90-axis position have a great influence on the thickness.
7) Round ones are thinner than square ones.
8) Lens size.
9) Center thickness of the lens
