The 1.67 is for use with powers over - 6.00 I don't know how Frank, calculates that, but it is 13% difference in thickness between the 1.61 and the The Lens Index number (1.50, 1.57, 1.53, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens.

Once you get close to -5.00 diopters, moving the index higher to a 1.61 is a good idea, if it fits your budget. From there, if you have a prescription over -6.00 diopters, a 1.67 high index lens is a worthwhile upgrade.

A higher refractive index indicates that light is more bended and spends more Jan 17, 2018 · For power around -4.00, choose 1.61 index, it will be around 3 to 4mm If your power is around -6.00, choose 1.67 index, it will be around 4 to 5mm For power more than that, choose the thinnest lens, 1.74 index. It will be around 5mm to 8mm.
