When dispensing such lenses the monocular pupillary distance (PD) and the face form angle (dihedral angle) are required to ensure exact centration.
We will use this to understand how single force-events are integrated at the scale of asters, how global forces may evolve will aster size, shape, in centration and de-centration processes, using various stages of development, and cell manipulation; and to compute aster friction.
Hybrid back-curve design The hybrid back curve design helps deliver a superior vision experience in two ways: first, the spherical periphery helps ensure centration of the optics over the pupil, and second, the aspheric center closely mimics the natural shape of the cornea to maintain the integrity of the complex front-surface optics.

This excerpt illustrates the concepts of egocentrism and how the young preoperational child "reasons" through imagination, transductive reasoning, and centration.
When testing the complex, the survey method (the accuracy of centration over points of the outer base, the method of determining the antenna height) and the subsequent data processing are assessed.

The XRD pattern in Figure 6 shows that increasing NaOH solution con centration favoured the formation of sodalite- and phillipsite-type zeolites, with a progressive decrease in peak intensity for the phases related to the minerals present in the starting materials.
Besides grinding and polishing these small lenses, Bern Optics also verifies the centration of each element before and after cementing.
