How to choose lens index

Lens index reflects lens thickness, there is 1.56, 1.61, 1.67 index etc.

The higher lens index is, the thinner lens is. 1.67 is thinner than 1.61 than 1.56 at the same degree.

Lens thickness also depends on frame size. The bigger frame is, the thicker lens is.

 

1.56 index suggestion degree:

SPH: -0.00 ~ -4.00;CYL: -0.50~-2.00

SPH: +0.50~+4.00;CYL:+0.50~+2.00
