LINED MULTIFOCAL LENSES
Lined Multifocal lenses are lenses that will correct multiple fields of vision in a single lens. Unlike a progressive lens Multifocal lenses have a distinct line that breaks up each of the visual zones. The use of the hard line in multifocal lenses are used to break up each zone and to create distinct visual zones. Replacement Lens Express offers the following Multifocal lenses.
BIFOCAL LENSES
Bifocal Lenses- The Bifocal Lenses provide visual corrections for 2 fields of vision, which are Distance (always on the top portion of the lens) and Near (aka reading, which is always on the bottom portion of the lens)
Bifocal lenses are also known as Straight or Flat Tops segments. The Bifocal lenses will have a horizontal D shaped segment near the bottom of the lens that will contain the near vision power correction. We offer 2 sizes of bifocals, the FT-28mm segment and the FT-35mm segment. Please be aware that the Bifocal viewing areas and segment sizes cannot be changed. The top will always be the distance viewing area and the bottom will always be the reading viewing area.
EXECUTIVE BIFOCAL LENSES
The Executive bifocal lenses provide visual corrections for both Distance and the near vision. They have a visible line that stretches across the entire lens, along with being visible you can also feel the line. The line is called the segment line and is used to separate the distance and near vision zones.
TRIFOCAL LENSES
Trifocal Lenses provide visual corrections for 3 fields of vision, which are Distance (always on the top portion of the lens) Intermediate (always in the middle) and Near (aka reading, which is always on the bottom portion of the lens)
Trifocal lenses are also known as Straight or Flat Tops segments. The Trifocal lenses will have 2 horizontal segment lines that run partially through the lenses. We offer 2 sizes of bifocals, the FT-7x28mm segment and the FT-8x35mm segment. Please be aware that the Trifocal visual fields and segment sizes are NOT customizable. The Intermediate zone width of the trifocal lens is dependent on which size you order for the FT-7x28mm it is 7mm wide and for the FT-8x35mm the segment width is 8mm wide.
EXECUTIVE TRIFOCAL LENSES
The Executive Trifocal lenses provide visual corrections for 3 visual zones, being Distance, intermediate and the near vision. They have 2 visible lines that stretch horizontally across the entire lens, along with being visible you can also feel the lines. These lines are called the segment line and are used to separate the different zones and make transitioning between the zones more distinct.
