Con riferimento alle gradazioni degli occhiali da vista, come si traducono?

UP+0,00, Down +1,50

Un po' mi inganna il segno positivo dopo il down, avevo pensato di tradurlo con +0,00, -1,50, ma non sono ferrata in materia e ho qualche dubbio.

Grazie per l'aiuto!

Reference: How to read eyeglass prescription

Reference information:
"When present, the amount of prism is indicated in either metric or fractional English units (0.5 or ½, for example), and the direction of the prism is indicated by noting the relative position of its "base" or thickest edge. Four abbreviations are used for prism direction: BU = base up; BD = base down; BI = base in (toward the wearer's nose); BO = base out (toward the wearer's ear)."
