Bifocal lenses combine distance and near correction in one lens, providing distinct viewing areas for everyday tasks. Our range gives independent opticians a choice of segment designs and specialist constructions to suit different visual requirements and wearer preferences. Unlike varifocals, standard bifocals do not provide a dedicated intermediate zone.

New Freeform Bifocal

Our freeform bifocal lenses combine distinct distance and near viewing areas with the precision of digital lens manufacturing. Computer-controlled surfacing allows the lens design to be accurately produced for the wearer’s prescription, while blended segment options offer a more discreet appearance than conventional lined bifocals.

For independent opticians, they provide a modern bifocal option for patients who prefer separate distance and reading zones.

Flat Top or D Segment

A traditional bifocal with a D-shaped reading segment, featuring a straight upper edge and rounded lower edge. It provides a broad near-vision area directly below the segment line, making it a practical option for reading and everyday close work. The distance and near zones have a clearly visible boundary. Available with 28mm, 35mm and 45mm segment.

Round Segment

A bifocal with a circular reading segment positioned in the lower part of the lens. Its rounded outline offers a less angular appearance than a D-segment. The usable reading width increases as the wearer looks further down towards the centre of the segment. Available with 24mm, 28mm and 38mm segment.

Blended Bifocal

A bifocal whose reading-segment boundary is blended to make it less noticeable, offering a more discreet cosmetic appearance. It retains distinct distance and near powers rather than the continuous progression of a varifocal. The blended area around the segment can introduce localised blur and does not provide a dedicated intermediate viewing zone. Available with 24 mm, 26 mm and 28 mm blended reading segments.

Curve Top or C Segment

A bifocal with a reading segment defined by a curved upper boundary rather than the straight edge of a D-segment. It offers a rounded, less angular segment appearance while retaining separate distance and near viewing areas. It remains a segmented bifocal rather than a blended or progressive design. Available with 28mm seg.

Lenticular Bifocal

A specialist bifocal construction used principally for high prescriptions, particularly high-plus corrections. The main prescription is concentrated within a smaller optical area, surrounded by a carrier zone that helps reduce lens bulk and weight. A near segment provides reading correction within this design. Lenticular describes the lens construction rather than the shape of the reading segment; the smaller optical area limits the usable field of vision.

Executive Bifocal

A bifocal with a straight dividing line extending across the full lens width, with distance vision above and near vision below. Its full-width reading area suits wearers who need extensive near vision, including some occupational tasks. The dividing line is prominent, making it less discreet than smaller-segment designs.

Choosing the right bifocal

Lens selection should take account of the wearer’s prescription, near-vision tasks, existing segment design and frame choice. Contact Insight Lenses for available segment sizes, materials, coatings and prescription ranges, together with
