Purpose:
To address the question, "How can we increase the bifocal contact lens market?"
Methods:
The design, lens parameters, and the results of a clinical study with this new bifocal lens are discussed. The contact lens market and current bifocal contact lens designs are reviewed and factors that should be considered in future lens designs are recommended.
Results:
The only hyper-oxygen bifocal available is the Menifocal Z (Menicon, Nagoya, Japan).
Conclusion:
Simultaneous vision, the optical design used in most soft lens bifocals, reduces visual performance. Industry and vision scientists need to develop new bifocal lens designs to help the bifocal contact lens market grow.
