In which prescription should I order the glasses?


The visual acuity measured by the optician refers to the typical distance to a book while reading. Since a navigation device or map is usually further away than a book while reading, a visual acuity about 0.5 Dp (dioptres) lower can be selected. In practice, this means that you only need + 2.0 Dp instead of + 2.5 Dp (normal reading glasses).
