Do I have to wear lined bifocals to read?
Lined bifocals are only one of many options available to people who require additional prescription power for reading. Lined bifocals have two focal lengths, distance (10 feet and beyond), and near (generally 12-18 inches), and there is a noticeable line differentiating these two areas. The modern spectacle alternative to traditional lined bifocals are progressive lenses, or no-line bifocals. As the name indicates, the additional prescription power for reading becomes progressively stronger from the top of the lens to the bottom. This allows for the proper prescription power at every focal length between distance and near. As a result, Progressives provide the most natural vision of any multi-focal lens without the line associated with traditional bifocals. Other alternatives to bifocal eyewear are contact lenses, either mono-vision or multi-focal contacts.
