With people increasingly working on computers either at home or at work, it is important to have the right lens for the job. The correct lenses have the following advanting:
Reading glasses cover a clearly defined distance (approx. 40 cm). They are not suitable for middle-distance and long-distance vision. If your customer reads a lot, recommend that they purchase this type of lens.

Vision up to approx. 4 m
