Abstract:
A bifocal lens is defined as a lens that has two parts of different focal powers. There are many types of bifocals: split, solid, embedded, welded and invisible. As the main disadvantage of image bounce, was due to the existance of prism in the movement of the gaze from one focus to another, they were replaced by multifocals. They have had great success replacing single vision lenses as well as double vision lenses. Over the years the popularity of multifocal lenses has stimulated the search for advances in multifocal lens design and manufacturing technology. Their evolution went from hard and soft type design to modern personalized design by modern CNC machines using Lasers and artificial intelligence.
