Bifocals are lenses that have two focal points. At Readers.com, our bifocal readers have unmagnified lenses which also contain inserts with the magnification of your choice in the lower portion of the lenses.Click to see full answer. Also, how do bifocal readers work?Bifocal glasses use 2 types of lenses connected together in 1 lens. Typically, the top half of the lens is used to see objects from far away, especially when driving or walking. The bottom half is a smaller portion of the lens that is used to see objects nearby, such as a book or newspaper.Similarly, how do I know if I need bifocals? You experience headaches, eyestrain or eye fatigue when performing up-close tasks, like handwriting. When driving, your vision is clear when looking out into the distance, but blurred when glancing down at the speedometer. The quality of your vision changes throughout the day. One may also ask, are reading glasses and bifocals the same thing? Single-vision lenses are also used for reading glasses. Reading glasses may either be prescription or over-the-counter. Unlike single vision, bifocals and progressives are multifocal lenses that have more than one point of focus, such as distance and near.Why do I need bifocals?Though multifocal lenses usually are prescribed for adults over age 40 to compensate for presbyopia, in some cases bifocals are prescribed for children and young adults who have eye teaming or focusing problems that cause eye strain when reading. The rest of the lens usually is for your distance vision.
