Bifocal Lenses are prescribed if you need correction for two fields of vision and a line or “Segment” separates the two focal points.
- The upper part of the lens is generally used for distance vision, while the lower part is used for near vision.
- Occupational bifocals can be specifically designed with the Intermediate or “computer” distance in the upper part of the lens and the “Near” or reading power in the lower segment.
- Bifocal lens design offer a full field of view in the upper portion and either 28 or 35 millimeter width for the lower portion.
- Unless otherwise specified in the notes section of your order we will assume the bifocal will be to correct distance and near vision.
