Progressive lenses Progressive lenses – without a visible cut, e.g. in bifocal lenses – the comfortable correction of presbyopia in combination with short-sightedness (myopia) and/or long-sightedness (hyperopia). The comfortable advantage is the smooth transition from near to intermediate and far distances, which largely complies with the natural visual process. The blurring on the edges of progressive lenses from technical contingencies varies and depends on the type of the progressive lens. This takes a certain amount of time to get used to. The goal of the progressive lens development is to reduce these restricting visual zones as much as possible, thereby increasing spontaneous adaptability. Through a combination of the most modern processing methods, e.g. freeform technology and incorporation of individual measurements and wearer requirements it is possible to provide progressive lenses like e.g. I´VISION. Compare the visual fields of the three different types of progressive lenses: Standard progressive lenses, modern progressive lenses and individual progressive lenses.
