 English term or phrase: vertex sphere Come tradurreste "vertex sphere"? - "The fitting cross corresponds to a lowering angle α of 0° and an azimuth angle β of 0°. The point of intersection of the rear surface of the lens and the axis Q’F’ is the point O. A vertex sphere, of center Q’ and radius q’, is intercepting the rear surface of the lens at point O of the horizontal axis" - "This enables to calculate the object proximity within a thin lens approximation for all points of the vertex sphere, which is used for the determination of the ergorama."

Inoltre l’ottimizzazione dei poteri veniva determinata nel
punto del vertice della sfera (vertex sphere) alla distanza
apice corneale-lente: l’assenza dei valori biometrici oculari
non può sempre garantire una perfetta nitidezza e campi
visivi ottimali.
