Since the launch of the Brien Holden Vision Institute (BHVI) Extended Depth of Focus (EDOF) multifocal contact lens design, practitioners and presbyopes have found new opportunities for success in this growing category.
The BHVI EDOF design has proven effective in helping pre- and early presbyopes transition from single vision to multifocal contact lenses. This opportunity is not just available to those with a simple spherical presbyopic correction, it is available with an extensive astigmatic correction range including 1 degree axis steps.
