Journal of the American Optometric Association
|August 1, 1984
Summary
This study introduces a novel technique for accurately determining bifocal lens size and decentration. The findings simplify the selection of multifocal lenses using provided tables.
Area of Science:
- Ophthalmic optics
- Optometry
Background:
- Accurate bifocal lens selection is crucial for effective vision correction.
- Current methods for determining bifocal size and decentration can be complex.
Purpose of the Study:
- To present a new, detailed technique for bifocal size determination and decentration.
- To simplify the process of selecting appropriate bifocal lenses for patients.
Main Methods:
- Detailed explanation of a novel technique for bifocal size and decentration measurement.
- Development of comprehensive tables correlating bifocal power, reading distance, and distance lens refractive power.
Main Results:
- The proposed technique offers a precise method for bifocal parameter assessment.
- The presented tables effectively reduce the complexity of bifocal lens selection.
Conclusions:
- The new technique and accompanying tables significantly streamline the process of bifocal lens fitting.
- This approach enhances the ease and accuracy of prescribing multifocal eyewear.
