2 STEP1) Select according to addition value2) Select according to specific needs

1) PD : Align web.lens Fitting Point with the near PD.

2) Eye point height : Align web.lens Fitting Point with the Eye point height for NV.

3) Minimum frame size : To assure the patient to enjoy the wide near vision of web.lens, we recommend maintaining aminimum of 15 mm between the FP and the bottom of the frame rim. A shorter distance will make it difficult to assure thesame Near Vision as reading SV lenses. The absolute minimum is 12 mm.Unlike PALs, web.lens has a Degression area above the FP. Be sure to check if the upper is not cut off. We recommendmaintaning a minimum of 20 mm between the FP and the top of the frame rim. A shorter distance will make it difficult toassure the same vision as what the patient has experienced with the web.lens trial lens. The absolute minimum is 15 mm.

Alignment of web.lens < basic method>

Recommended height

If it is impossible to measure the Eye point height for NV or near vision PD and the FarVision Eye point is used as the reference for framing, we recommend matching the "virtual"Far Fitting Point to the Eye point for FV.This is because that compared to Far Vision, Near Vision usually has a smaller PD and theline of sight is lower.

The standard expression of the Far Eye point is:Eye point for NV= 2 mm inside and 4 mm below the Eye point for FV.

It is not a very acurate measurement method, but, in most cases, web.lens Near Vision is wide enough to cover it.
