The Nikon Online lens is specifically designed for mid distance viewing. The lenses provide wide vision, and minimizes the need for head and neck movement found in other lenses.
Most progressive lenses are made up to give clear vision over all visual zones, however vision is not all about clear vision. Nikon Online lenses are specially designed for long time use for intermediate and near vision e.g. computer use; and minimise the head and neck movement that are needed for less specialised conventional progressive lenses.
Ordinary single vision lenses are often not versatile enough for viewing objects that are further away (three metres for Online) and progressive lenses are not specialised to offer the width of vision required for comfortable long period intermediate use; Nikon Online has been specially designed for this purpose and will give you the clarity of vision exactly where you need it.
