Fresnel lenses can capture more oblique light from a light source, thus allowing the light from a lighthouse equipped with one to be visible over greater distances. Fresnel lenses were later produced, being used for automobile headlamps, brake, parking, and turn signal lenses, and so on. In modern times,computer-controlled milling equipment (CNC)might be used to manufacture more complex lenses.
