FOCAL bi-Multifocal Toric
FOCAL bi-Multifocal Toric – vision at all distances, even with astigmatism
FOCAL bi-Multifocal Toric combines a simultaneous-vision multifocal design with toric stabilization (peri-ballast) to provide sharp vision at all distances for wearers with astigmatism. The lens is available in two optical designs: Center Near (base curve 8.60 mm) and Center Distance (base curve 8.70 mm)..
- Simultaneous vision design with toric stabilization
- Available as Center Near (CN, 8.60 mm) or Center Distance (CD, 8.70 mm)
- Two add powers: Low (+2.25D) and High (+3.25D)
- Orientation mark at 6 o'clock for easy checking
