Frequently Asked Questions
Reading power is primarily based on age (due to presbyopia progression) and working distance. As we age, the lens inside our eye loses flexibility, requiring additional plus power for near tasks. The standard reading distance is 40cm (16 inches), but your specific needs may vary based on hobbies or work.
