• Cylindrical lenses bend around the face on an east-west curvature (the north-south axis is flat). In layman’s terms: It’s like a curved piece of film, right down to the way the lenses reflect light in neat little vertical strips.
• Cylindrical lenses appeal to the fashion sense because they eliminate
that ”bug-eye” look so common with larger frames—actually looking smaller than they are because they hug the perimeter of the face.
• From a technical sense, these lenses not only offer the sporty, high-tech look that’s so desirable, but also provide distortion-free vision.
