[degree selection]
No astigmatism
If your eyes do not have astigmatism, choose lenses according to your degree.

Example: Myopia is -5.0 degree,choose -5.0(-500) degree lenses.If myopia is -4.7 degree,choose -4.5(-450) degree lenses(There are no lenses with the same degree of myopia as you. Choose lenses with a lower degree of myopia than you.).

Has astigmatism

If the astigmatism of the eyes is high, please choose lenses that are -0.1 to -0.5 less than your myopia.
Because the refractive index of water is different, it is necessary to subtract 0.5(50) degrees to avoid excessive height, which will make people easily dizzy.

Example: Astigmatism is 1.0(100) degrees, myopia is 5.0(500) degrees, then 500-50=450 degrees, Then you can choose -4.5(-450) degree or -5.0(-500) degree lenses.
