Progressive lenses are the most evolved optical solution for your eyes, because they allow you to see in a clear and natural way at all distances, avoiding the unpleasant put-on/ put-off that doesn't value your image.
Technical structure of progressive lenses:
Area for far distance: the upper part of lenses is meant to vision at far distance, for example when you drive the car, you watch a movie to the cinema, or simply walking and looking at landscape.
Area for intermediate distance: the intermediate area, or progression corridor, is the central part of lenses, where the corrective power gradually passes from correction for far or close distance.
The width of this area depens on the powet, geometry, and on lenses choosen according to your lifestyle. Although it is the more narrow area of lenses, it allows to see clearly at intermediate distancesm for example the computer screen, or the car's dashboard.
Area for close distance: this area is situated in the lower part of lenses and it's menat for the reading or the viison of objects at a very close distance. In this area the corrective power gradually increases, up to reach its maximum in the lower part of the lens. This guarantees a wide and comfortable vision.
Peripheral areas: the so-called peripheral areas of progressive lenses are the more blurred areas of progressive lenses at the sides of the lenses. These areas cannot be completely eliminated, but, if you follow attentively the advices for theur use, this perception of blurring will be gradually reduced.
It will all happen in a natural way…
