What you actually "see" with progressive glasses The
narrow field of vertical undistorted vision lets wearers of progressive
glasses clearly see only a narrow vertical strip of text. Moving their
head lets them move that undistorted area around the page on the screen, but
the reduced peripheral vision makes it difficult to efficiently comprehend
text and concepts. (Yes, the distortion below IS exaggerated to make
the point more obvious.)
