No Line Bifocal glasses also called progressive lenses will allow you to see at all directions including near, intermediate and distant vision. No Line Bifocal glasses have multi prescription powers in the same lenses, so people who get presbyopia and also need vision correction for nearsightedness can benefit from progressive glasses which allow them to see close-up objects and the distant objects clearly at the same time without changing glasses. The bottom part of the progressive lenses are used for close-up work and the top part of the lenses are used for distant vision.
