What do Far PD/Distance PD & Near PD mean?

When we talk about PD (Pupillary Distance), we need to distinguish between:

Far PD/Distance PD: it is used for single vision eyeglasses and refers to the distance between the centers of the pupils, when the user is looking at a distance. This measure is often used for most prescription eyeglasses for example.
Near PD: it is used for reading eyeglasses and refers to the same measurement but when the user is looking up close, such as when reading a book.

For most people, the difference between Far PD/Distance PD and Near PD is about 2-3mm.
