The correction does not go all the way across the lens but is shaped like an hourglass down the center of the lens. It is expected to take some time to get used to this lens type.

Progressive lenses in the history of the development of the lens for the first time in a very non progressive change of the lens. This change makes it easy for the designer to get the continuity of the different distances.
The design producers of the progressive lenses also designed different types of progressive lenses based on the different use environment of the wearers of the wide spectacle frames.
For example, such as progressive lenses designed for astronauts, we specially designed to see the lens area of the upper and the lower distance instruments, and the progressive lenses, which are designed for office workers, which are suitable for use in the near distance work. They are also called office films.
It is worth mentioning that in recent years, a new adolescent progressive lens has been developed for teenagers, which is specially designed for preventing and controlling myopia.
