ST 1.60 Acrylic High index is one of the most advanced lens material available today ( none MR material). When utilized properly it provides a thin profile, lighter weight and advanced optics to the patient.
The 1.60 High index plastic offers the biggest benefit to minus prescriptions, where the edge of the lens is thicker than the center and therefore, easy for the patient to notice. Plus lenses can also benefit
from high index materials.
Thinner: Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges than lenses with the same prescription power that are made of conventional plastic material.
Lighter: Thinner edges require less lens material, which reduces the overall weight of the lenses. Lenses made of high-index plastic are lighter than the same lenses made in conventional plastic, so they’re
more comfortable to wear.
The 1.60 Acrylic series is not suitable for rimless glazing.
