  • Bifocals are a type of prescription eyeglasses designed for people who need both near and farsighted vision correction. Bifocals have two corrective lenses on each side of a pair of glasses, on top for far away and a different prescription on the bottom for near. Progressive lenses are used in eyeglasses to correct presbyopia and other disorders of accommodation. There are three basic ranges of vision. The near range is for reading and seeing up close. The mid-range is for seeing things at arm's length. The distance range is anything farther away like road signs.
  • Bifocals are most commonly prescribed to people with presbyopia who also require a correction for myopia, hypermetropia, and/or astigmatism. For reading is that they save the wearer from having to constantly switch between different pairs of glasses. If you are reading a book, and look up from reading, your focus will automatically be through the upper part of the lens – the distance lens.
    Progressive lenses are true "multifocal" lenses that provide a seamless progression of many lens powers for all viewing distances. With progressive lenses, you can look up to see clearly across the room and in the distance.
