Import Tips
• Provide fitting cross-correlation data showing designed for standard frame fitting heights (16-22mm)
• Include manufacturing tolerance certificates (±0.10D power, ±1' prism) to verify optical workmanship
• Avoid generic 'multifocal' labeling; specify progressive design to distinguish from lined bifocals
