Choose a lens shape: Cylindrical lenses look flat and are curved around the face on the vertical axis. These are cheaper to manufacture than spherical lenses, and when used on a large pair of goggles can offer a vast field of view. Spherical lenses are curved both vertically and horizontally and give the goggles a bug-eyed look. Spherical lenses help to open up more of the view, especially the up and down aspects. You’ll pay more for spherical lenses, but they can be truly impressive.
