Breakdown of Lens Index of Refraction

Below is a chat of the various lens options that we offer here at JINS (with their index of refraction):

*1.74 index is available only for single vision clear lenses, and it is not always guaranteed to offer to all prescriptions with sphere power -8.00 and higher. Also, depending on your selection of lens option, the high index availability is limited.
