CONCLUSION Power mapping is a useful tool to evaluate relative sim- ilarities and differences in power profiles of aspheric mul- tifocal contact lenses. With varied viewing distances for digital devices, three distinct zones that concentrate light should provide excellent utility for advanced presbyopia. REFERENCES 1.
