Multifocal contact lenses are contact lenses with multiple prescriptions all in one lens. There is typically a prescription for very close objects: one prescription for normal objects viewed at a distance, and then prescriptions for intermediate distances. This setup helps people with vision problems where the eye can no longer focus on objects up close.
Monovision contact lenses are one of several common ways that people correct for presbyopia as they age. In order to address the difficulty in changing focus between near and far, one contact lens is prescribed for near vision and the other contact lens for distance.
Toric contact lenses are often the best choice for contact lens wearers with an astigmatism, because they're specifically designed to address the problem. The special shape of a toric lens creates different refractive, or focusing, powers that can help correct either a corneal or a lenticular astigmatism
