The top portion of the lens provides long distance vision and the small section between the two &#; the so-called transition or progression area &#; ensures perfect vision at all progressive distances, for instance to see things displayed on a monitor. As a result of the manufacturing process, the edges of this area are out of focus &#; and the severity of this differs depending on the quality of the progressive addition lens design and the level of customization.
