===Multifocal===
Multifocal contact lenses (e.g. bifocals or progressives) are comparable to spectacles with [[bifocals]] or [[progressive lens]]es because they have multiple [[focus (optics)|focal points]]. Multifocal contact lenses are typically designed for constant viewing through the center of the lens, but some designs do incorporate a shift in lens position to view through the reading power (similar to bifocal glasses).
