摘要:
Progressive multifocal ophthalmic lens having a power addition (Add) and an astigmatism prescription, and having a far vision point CM, a near vision point NV, and an intermediate vision point IV positioned between CM and NV. The resulting astigmatism in the far and near vision zones is smaller than or equal to the resulting astigmatism in the intermediate vision zone, wherein the resulting astigmatism is the difference between the prescribed astigmatism and the astigmatism generated by the working lens under usual wear conditions. The lens provides good optical quality images in the far and near vision zones, and the resulting astigmatism in the intermediate vision zone encourages the wearer to use the far and near vision zones rather than the intermediate vision zone, thus reducing the risk of increasing the degree of myopia of the wearer in the long term.
